The best waterproof fitness trackers for swimming in the pool

Fancy hitting the water rather than the roads? Check out these top waterproof bands
​The best waterproof fitness trackers

For many people looking for a fitness tracker for swimming, the waterproof rating is the most important factor.

That's why we've picked the best of the bunch of 1 ATM and IP68 rated bands that can survive a dip in the pool, which should be on the shopping list for any swimming enthusiast.

Essential reading: Waterproof vs water resistance explained

But we realise that while these kinds of buyers' guides are a decent introduction, you also really want to know just how they perform in the pool. That's why we've also put together the ultimate swimming tracker group test, to find out what they're like in the water. It's essential reading for anyone considering a purchase.

Garmin Vivoactive HR

best waterproof fitness trackers

The Garmin Vivoactive was the winner of our group test, and with the Vivoactive HR, you're getting more of the same in the swim tracking department. It's simply one of the best all-purpose trackers out there.

Garmin seems to take waterproofing more seriously than most other manufacturers, and this is the first of three devices from the company in our round-up. The Vivoactive HR has a 5 ATM waterproof rating — resistant to pressure at a depth of 50 metres — as well as a dedicated swimming app which collects data on distance, time, stroke, SWOLF, temperature, pace, speed and more.

Waterproof rating: 5 ATM (50m)

Fitbit Flex 2

best waterproof fitness trackers

Fitbit fans should be happy they've finally got a swim friendly option in the form of the new Fitbit Flex 2.

It's water resistant to 50m in the pool, ocean or shower and brings a five day battery life, LED light alerts and fancy accessories to the usual Fitbit features of activity and sleep tracking. On sale this autumn for the same price as the original, there's four default bands and also stainless steel and gold options.

Waterproof rating: 5 ATM (50m)

Moov Now

best waterproof fitness trackers

More than just a tracker, Moov Now is about built-in coaching, which is designed to offer metrics on improving your swimming rather than just feeding back on it. Waterproof to 50m, the new Moov app has a dedicated swimming mode that you turn on before you leave the changing room.

When you get back you'll see feedback on your stroke type, rate, distance and efficiency, as well as lap times and an overall indicator of your pool stamina.

Waterproof rating: 3ATM (30m)

Misfit Speedo Shine

best waterproof fitness trackers

We've already put the newer Speedo Shine 2 through its paces in the pool, but weren't all that impressed with the performance. So we'd suggest sticking to the original for now until some software quirks are sorted out.

The Speedo Shine can be worn on the wrist or attached to your trunks, so it's flexible as well as waterproof, and it carries a 5 ATM rating, which means it will survive continued immersion at depths up to 50 metres.

The collaboration with the swimming apparel giant means it also boasts swimming-specific algorithms that track laps and lengths as well as distance and calories burned.

Waterproof rating: 5 ATM (50m)

Garmin Vivosmart HR+

best waterproof fitness trackers

The Garmin Vivosmart HR+ is in our opinion the best fitness tracker for running and one of the most advanced trackers available. Yet in this list it's the 5 ATM of waterproofing that's the icing on the cake.

While it doesn't have a dedicated swim mode like the Vivoactive HR or more expensive Garmin wearables, you can take it into the pool and workouts will count against your daily goal. You can also check out your notifications when you return to the locker room.

Waterproof rating: 5 ATM (50m)

TomTom Spark

best waterproof fitness trackers

The Spark is more watch than fitness tracker, but it does have a dedicated swim mode that helped it earn second place in our big swim tracker test.

There's a surprising amount of data on board here including miles, speed, lengths and swolf scores. You can choose pool sizes to ensure lap counting is accurate, record split times and pick from a bunch of training modes including intervals. There's also a Goal mode which offers an excellent in-pool view of how far your session you are along with extra buzzes should you surpass your expectations.

Post-swim analysis is not great, but elsewhere this is a solid tracker to go swimming with. The new TomTom Spark 3 also includes the same swim tracking features so it's worth keeping that in mind.

Waterproof rating: 4 ATM (40m)

Garmin Swim

best waterproof fitness trackers

While not strictly a fitness tracker, if you're a serious swimmer and want to track your pool performance more than any other type of activity, the Garmin Swim is top dog. It tracks the distance you've covered, the number of strokes you've made, plus the stroke type, and with a 5 ATM rating it can withstand continued immersion at depths of up to 50 metres.

Waterproof rating: 5 ATM (50m)

  • davidac says:

    jawbone had informed me that the up 3 is not water proof but only splash proof

  • kat72 says:

    This information is good in theory but what about warranty information.  I have heard of some of these devices breaking when worn swimming or surfing and did not go beyond 2 meters let alone 10.  Also information on app interface would be nice since many are lacking.

    • hskonk says:

      I have a Garmin Vivosmart that stopped working one day after swimming (it was great for about 6 months before that). I returned it to Garmin and they sent me a new one right away.  It was great warranty service!

  • Diverjake says:


    thanks for the infos, just a correction 2 ATM doesn't means 20m depth, it means 10m.

    2ATM = 1ATM at sea level + 1ATM at 10m depth.

    5ATM means 40m depth.

    I am a diver and I know what I am talking about.



    • DMFreeman says:

      Common misconception. I used to think the same.

      5 ATM (atmospheres) is 50m of water pressure.

      You're thinking of ATA (atmospheres absolute): where you add the water pressure (ATM) to the existing atmosphere above sea level.

      So 5 ATA would be 40m.

      They don't take these things diving, they test them in a water pressure chamber to simulate the 5 ATM, but if you were moving at that depth it would exert far greater pressure... so even the Garmin's aren't really tested to go to 40 or 50m.

  • SwimmingTony says:

    Bought the Polar Loop 11 months ago.  Battery Life between charges is WAY too short.  Only way to download to computer is via USB wire and now the connection between loop and USB fails so the download function no longer works and the loop itself is useless as the data "file" in the loop is full.  And try getting someone at customer service????  Not even one year old. Instead of perfecting the device, they've decided instead to make sure we can see what another Loop owner in Denmark is doing with their Loop instead.  Don't buy it.  

    • nelsongruber says:

      You can send the data to your iPhone or Android device via bluetooth. Also do a Factory Reset and you´ll have amazing battery life again. I´ve had mine for over a year now and I love it.

      I´m looking to buy a new one but only becuase I need Heart Rate when I´m swimming and the Polar Loop + H7 can´t do it.

      Hope it helps!

      • neta says:

        Hi, which one would you recommend for heart rate tracking.


    • Loubee says:

      I have had my Polar Loop for 19 months. No trouble at all. No trouble downloading. I download and charge every two days. Takes about 15 minutes.

  • Cderickson says:

    the basis does not track swimming activity. Got one for Father's Day it's waterproof but doesn't track laps or any other functions while in the water.

  • JogBikeSwimGirl says:

    Don't bother with the Misfit Shine.  It does not stay in it's cheap plastic band,   nor will it stay in the expensive ones they sell.  It constantly pops out and will attach itself to anything vaguely magnetic.

    • Walker says:

      I agree. I lost a Shine with the expensive band and almost lost one with the cheap one. After complaining (a lot) to them, they sent me the sport necklace and that has done the trick. I wear it constantly, day and night, without any problems or near losses. It even tracks my steps better than with the arm bands because it isn't as dependent on arm swing. Of course, if I want to swim or bike, I have to wear a band or use the magnetic clip. 

    • Piksea says:

      And, the Misfit Shine paperwork says that it gets ruined by prolonged contact with salt and/or chemically treated water.  So, not really good for swimmers. I've been through 4 of them at this point and the longest one has lasted is about 9 months.

    • Bendita says:

      Absolutely true. Misfit is no good. Mine stopped working altogether after just half an hour of swimming.

  • lnewstadt says:

    Garmin Vivoactive any thoughts on this watch, pity it does not have built in heart monitor?

    • smileman says:

      Two ways to go with the waterproof Vivoactive: 

      a) activate the activity tracker to record time and then add the swim distance, estimated calories burned, etc later in the Garmin Connect web app, 

      or b) use the Vivoactive swimming with either a Scosche Rhythm + or Mio Link (although I've read mixed reports on how well the Mio works compared to the Scosche) to track your heart rate and get the accurate calorie burn from the swim.

      • Oceanlv says:

        I love my Vivoactive. I initially got it to track my running sessions, but because you can download apps for specific use, I have gotten into circuit training, swimming etc. I downloaded an app called work out genius. You can customize the app up to three different types of workouts, including open water swim. I live in Florida so in the summer I am either at the beach or the pool. My Vivoactive never leaves my wrist. I always clean my Vivoactive because I know that both the salt water and chlorine can be corrosive, but I haven't had a problem yet and it's been two years. I usually pair it with the Garmin chest strap, but since I would like to track my swimming, I am on the hunt for a heart rate monitor that I can wear on my wrist. I looked at both the Mio Link and the Scosche. I ended up buying the Mio. I haven't even received it yet so I will have to come back to let you know how it works.

        • offbyte says:

          I'm on the same hunt too, how is the mio going so far?

  • onealioop says:

    I have the Misfit Shine. I love the waterproof and sleep and watch function. Tracking laps is non existant... tracking swim time is accurate. I concur with Jogbikeswimgirl, the bands are an issue.  Im on my third black sports band.  They pop out with catching on items sliding down your wrist. The magnet clasp works on shirts only. Feet and pants it pops off with centrifugal force. The bands with the metal bung work best. Plastic ones fail and colors weaken the rubber ring that holds it in place.  Anyone try the speedo sponsered one yet?

    • LMH says:

      thinking of getting one, could you not glue the thing into the band?

  • iAndy says:

    I have read loads of articles, I'm just after a good swim tracker! I think I have settled on Moov Now, claims to be a coach as well as tracker giving feedback on your swim stroke as well as the usual. It's available for pre-order now

    • Swimmer says:

      Moov is total garbage. It has never once worked because there is simply not enough information on the screen to indicate that it is actually tracking anything. Every single time, when I synched to my phone after my swim, it was messed up. Total waste of money. 

      • Storm8 says:

        Works for me, tracks quite accurately only for the calories burnt which once was tracked as over a thousand calories for a 30 minute swim. After the recent update it's tracking about 700 - not too sure if this is accurate but it does count / recognize laps accurately.

  • LifeTrak says:

    • HueyDueyDuck says:

      Is it available? I walk against the current in a Lazy River pool.

  • sdanzger says:

    This is a really useful article.  I'm still having trouble figuring out an affordable solution that will enable me to track both my heart rate and workout with intervals.  Any suggestions?

    • j.stables says:

      TomTom Spark is worth a look.

  • Jayesh says:

    thanks for the info but pretty contradictory comments. Is there a latest scoop for these?

  • lynne says:

    I bought a Fitbit Flex and it was supposed to be water resistant to 1 meter but it's not. Water resistant according to the manufacturer help line is 'Splash proof' and even then not advised to be taken into the shower. 

    • Acorp928 says:

      I've been wearing my Fitbit Flex in my pool and shower for 4 years now and purchased a new one for my wife last year.  We still have had no problems.

    • Neil says:

      Same here . . . wearing Fitbit Flex for 18 months in the pool [twice a week].  No problem.  Still works with no problem.

  • nayers says:

    Just bought my husband the iFit Vue for Christmas.  It looked good initially, as it tracks steps and laps, but when he went to download the app everyone said that it was horrible.  any reviews out there on the iFit Vue?  if you were to recommend one of the above for him (former swim team member, would rather swim for cardio than do anything else), which would you recommend?

    • m.sawh says:

      Unfortunately, we haven't reviewed the iFit Vue. If I had to make a recommendation, I'd say the Garmin Swim or the Moov Now would be a good fit from this list. If you wanted something that's capable of heart rate monitoring in the water, then the Suunto Ambit3 Sport is worth considering as well (

      Hope that helps,

  • TAT says:

    Enjoyed the article. I'm looking for something I can use in and out of the water. Swimmimg lap, aerobics and walking the dog. Recommendations?

  • moovover says:

    why is tech journalism so bad? Bought a mood now based on the review here - an utter rubbish piece of equipment. It is inaccurate on lengths and distance - one every 5-7 swims i smash olympic records according to this thing. And you cannot override the data. on looking on their forums available via their app i learn many have same/similar problems. Why is wareable not doing proper testing?? Are they just being paid by these companies.. Sloppy product and sloppy journalism. Waste of 100 dollars. recommend not to buy or trust the reviews on this site 

  • Strupo says:

    I bought the Garmin Vivosmart HR so I could track my heart rate while swimming. I was having issues with getting a good reading so I asked Garmin, and while the and is suitable to swim with, the heart rate feature does not work underwater. Just an FYI for anyone considering this band to use in the pool.

    • Suyash says:

      Hi Just read ur post. Wanted to know rather reassure myself that is Garmin Vivosmart HR is it good for Swimming as I am planning to buy one. As per ur post it appears to be yes. Ps update me.

  • Tibor says:

    So guys, which one would you recommend? I`m doing swimming (interested in laps=distances mostly, others are welcome) and mostly running (distance, route would be nice too=gps if possible; calories etc.). But don`t want a sport there a band or like withings watch looking tracker at all?

  • Tibor says:

    Hi there,

    so guys what would you recommend as my activities are mostly swimming, running and working out, rarely volleybal.

    But I`m looking for accurate measurement, in an app is fine, no need for a display..

    I`m not looking for a sport professional watch, unless it looks cool as withings activite..

    Is there a tracker like that at all?

  • Kaydub says:

    Particularly interested in a waterproof tracker for swimming in an endless pool. Laps mean nothing. Looking for heartrate and calorie burn for durations of time. Any thoughts?

    • sedgy says:

      Not sure about how it would work but one of the garmins that are comaptible with their HRM swim/tri hear rate bands might do it these count strokes, laps (or not in your case) and the stroke you are performing, the open water app they have might prove better than the pool swim and just turn off the GPS.Alternatively wahoo do a HRM that works in the pool and then syncs with an app on your phone for HR and estimated calories take a look over at DC Rainmaker site for coverage of most of this stuff and more :)

  • AmyS says:

    I am a novice and after a fitness tracker for swimming and cycling that communicates with Strava if possible. Any suggestions? 

  • Nfritts says:

    I am wondering, how well do these things track calorie burn for water aerobics? 

    • j.stables says:

      You'd need a tracker with a heart rate monitor for that really – and of course, something waterproof. Vivosmart HR would be best – the Shine would do an OK job of guessing.

  • Skinz says:

    A reasonable simple summary but ...

    Optical heart rate monitoring, in my experience so far doesn't work too well in the pool, yet.  This leaves only a few options if that is what you want / need and for a bloke that means a way to keep the heart rate band secure while you swim.  And in my experience that means wearing a Tri suit as that is better than using tape. If you want / need this functionality there are options, though not many (DC Rainmaker' site has loads of detail) but I've ended up with Polar and a realtime HRM display with swimming metrics and activity monitoring on a V800 / H7 combo - which does the metrics even without the HRM.

    The Misfit Speedo Shine works well, especially with the newer activity clasp that keeps it more secure, too.  And the results for calories and effort are not noticeably different to the complex answer, even for a bog standard Shine either.

    Bottom line, unless you have a real need for HRM in the water it's not a deal breaker and most more complex Eco systems (Polar, Garmin, Suunto etc) have ways to add it in.

    Still no "love" for the Basis Peak....

    • Fr8Broker says:

      Wait!  I scrolled to fast and I can't figure out how to delete my comment!  There is "love" for the Basis Peak!  My faith is restored!

  • Raja says:

    caution. My six month old vivosmart is looking pixels.  Looks like a common problem too.  Don't recommend. 

  • Andea says:

    Anyone try the Waterfi waterproofed Fitbit charge HR wireless activity tracker with heart rate monitor? Waterproof for about 64m. 

  • Peer200x says:

    I had the poor loop for the last three or four summers.   It was great being able to wear it out in the ocean for my swims.   Having to connect it to my PC was painful but the activity tracker was spectacular.  I really enjoyed being able to monitor my activity level throughout the year and compare months from year-to-year and seeing the difference of summer activity versus my winter activity.   Unfortunately the bat became weak. Eventually on my fourth summer the battery completely died. Frustratingly I tried to call or contact their customer service to receive a replacement battery and could not seem to get through to polar Loop customer service. 

  • fiona says:

    I'm a little confused now after some comments contradict the article... Help!

    I'm pregnant so monitoring my heart rate whilst swimming is important so I don't let it get too high. It's hard when you don't quite feel the sweat in water as you do 'on land'! I'm looking for a heart rate monitor that can constantly measure my HR underwater and beep when it hits my manually entered limit. At this stage I don't care whether it measures it at the wrist or I need an extra strap, but it needs to still work underwater....and beep at me!!! Was leaning towards the garmin vivosmart then saw a comment that it doesn't actually measure HR underwater.

    I would really appreciate some help with this, budgets are tight with little one on the way so if anyone knows of a cheaper option that's been released post this article that would be great too.

    Thank you

    • j.stables says:

      To be honest there's very little out there that can fulfil this reliably on a budget. And for such an important task. Garmin Vivoactive HR might be best but I'm not sure there's an alert for high heart rate. What bpm are you looking to stay under?

  • sandrinefnyc says:

    Just bought the shine 2 because it said that it was better and improved and that it didn't pop as much ! BIG MISTAKE !  First of all i had purchased shine 2 with a sports necklace that NEVER CAME . So i paid $49 and no product , but the shine 2 stopped working after only after 4 days and had already popped like 4 times, and lets not talk about the fact that the customer service is NON EXISTENT . I emailed them and have yet to get a response . so if you are considering buying something do it with a company that has a telephone number because now looks like i spent $150 for NOTHING .... SO UPSET !

  • LucyCave says:

    I am a casuals swimmer but I swim in a static pool so there are no lengths. Is there an all round  fitness tracker that could cope with this?

  • laurenbolda says:

    Basis Peak has now been found to burn either the skin with contact or the charging puck on a few devices - anyone still reading this post may want to consider another model.  I personally submitted mine for a refund, and the company will no longer make them until they have resolved the problem.  I was very happy with this product during the time that I had it though!

  • Abk says:

    somebody help me I want an waterproof all around fitness tracker.Any ideas

  • swoman says:

    I swim in open water. I am not an open water swimmer. I poddle. I enjoy the birds and the feeling of the water. All I want is one device that will tell me the temperature of the water, the distance I have swum, and that is completely waterproof. Please someone make a suggestion.  Thanks.

  • Janet says:

    I'm exhausted just reading all these comments - and still non-the-wiser, really.... Just want a simple waterproof tracker for cycling, exercise classes and occasional swimming, with a heart monitor - and a colourful, reliable band, ideally... Surely, that's not too hard to find?...

    • GaryAnton says:

      I feel exactly the same!  I want a waterproof tracker for swimming, with a heart monitor.  Seems that the technology is not exactly there yet!  - Gary

  • doghiker says:

    I don't care about the HR or the sleep monitor, because there is no way I am wearing a watch to bed.  All I really want is the swimming and the hiking, and a GPS would be nice.  I really don't want notifications of texts, I'm not that attached to my phone.  But the GPS units are reviewed as bulky, which is hard for a lady with a kid.  Are we expecting these things to only last a year?  Because if they are so disposable I can just get the cheapest one and hope for a proper upgrade one day.  

  • Selkie says:

    I've been using the Fitbit HR for the past year (had to be replaced once due to the charging bit falling out). But I love to kayak and swim in the pool and ocean, so I'd like a tracker I can leave on in the water - and be able to check the time - but can also take a beating from the waves, boogie board, and (eventually) surf board and SUP. A couple of trackers not mentioned here: Fitbit Flex2 just came out, but despite being affordable, "swimproof" (site does not state depth) and able to pretty-up with a variety of bands, does not have a watch and the band looks like it will snap off with the first wave. Samsung Gear Fit2 has great bells and whistles for the price, but also has a band that looks like it will snap right off and "P68 rating means it’s water-resistant in up to 5 feet of water for up to 30 minutes".  I'm in the water a lot longer.

    So I'm leaning toward the Garmins:  Vivoactive or new Vivoactive HR (but they look huge for a slim woman's wrist and are pricey) - or the less expensive and slimmer Vivosmart HR.

    I've read the article and the comments and still cannot decide. 

    Any other waterproof favorites for a great tracker with a watch that can take an active lifestyle?  Any other comments on the Garmin choices?

    • mfar11 says:

      Yeah, got muddled reading all these reviews too. Came down to these two based on intended use (simple to use tracker for walking, swimming and running): Polar A300 + H7 strap or Polar M600 + H7 strap. Both will track HRM in water if used with the H7. (may be possible to pair A300 with H1 strap which also works in water to track HRM).

      I chose the M600+H7 strap because I wanted a combo smartwatch/tracker. In hindsight, for the reason that I can always check data later once synced with my PC after the event, I should have gone for the simpler and cheaper A300+H7 strap. And the screen is always on and battery lasts for quite a bit. I also have an older Polar FT4 with bundled H1 that will track HRM underwater but my eyesight is not as sharp as it used to be.

      My friend has a Garmin Vivoactive. I looked at the Vivoactive HR+ but pulled out cause I really wanted an HRM.

      • mfar11 says:

        Should have reviewed last para. I didn't go with the Vivoactive HR because its optical HRM is not able, as I understand it, track heart rate in water and can't be paired with Garmin's own "swim" strap that can do that (only certain units like the dearer Fenix 3 will pair with that strap). 

        • neta says:

          Hi, which one would you recommend for heart rate monitoring (for swim)?


  • ELTON says:

    I had a Basis Peak until it was recalled recently by Intel not to be replaced. Because I wear my trackers constantly, shower, swimming etc. I needed a waterproof model. I ended up buying the FitBit Blaze from Waterfi. They take the Blaze and fully waterproof the watch. You do lose the altitude feature but that was not something I looked for anyway. I have had it for two months now and no problem. I do hope they come out with more watch faces, one with just large digital numbers for telling time that can be read in sunlight like I had with the Basis Peak. The only complaint I have is battery life. They advertise up to 5 days but you only get that using minimal features. If you use all the features offered battery life is about 60 hours.

  • dm33 says:

    I currently have the Moov Now, Garmin Vivosmart HR and Polar A360.

    For swimming I vote for the Polar A360, ~$150 @ Amazon. It has a heart rate monitor which has been very accurate for my uses.

    The Moov Now does an excellent job tracking laps, pace, strokes, distance per stroke, but its lacking as a general fitness tracker. Doesn't track steps. Poor general tracking. Buggy.

    The Garmin is temperamental in the water. Heart rate is erratic. You have to record a swim as a walk or something else then switch it to a swim after syncing with your phone. It then loses the heart rate graph but keeps the erroneous max heart rate and average heart rate. The Polar does much better. The Garmin touchscreen also goes nuts when water hits it.

    In summary, take a look at the Polar A360. Its sleep tracking is poorest of the three, notifications aren't as good as the Garmin, but for heart rate monitoring, its the best, especially in water.
