Google Fit wasn't much to write home about when it first appeared in 2014, but it's slowly been gaining extra features and functions over time, and there are now dozens of apps and wearable gadgets that plug straight into the platform offered by Google.
Google Fit is focused mainly on collecting stats — on activity, sleep, weight and so on — rather than providing the comprehensive, all-in-one overview of your health and medical records that Apple Health wants to be. Fit is more basic, but it's easier to use.
The Google Fit app is free to download for Android devices and once you've got it up and running it can use the sensors in your phone to track your progress. You can also add activities manually, or use one of the following apps or gadgets for the job instead.
Best Google Fit compatible devices
Fossil Q Founder
For those of you who prefer a bit of style with your step counting, give the Fossil Q Founder a look: it blends Android Wear with the style and expertise of Fossil to come up with something that looks good and works well. And of course, there's Google Fit integration.
Moto 360 Sport
Any Android Wear smartwatch is going to provide seamless syncing with Google Fit (and indeed you can use a Fit widget as the watch face if you want), and the Moto 360 Sport is one of the best: lots of customisation options and a sportier look than most of its rivals.
Sony SmartBand 2
This rather plain-looking fitness tracker from Sony may not win any best-in-class awards but the integration it offers with Google Fit may tempt you to choose it over its rivals. It's affordable too, and has an integrated heart rate monitor as well as all the essentials.
Under Armour Band
Fitness experts Under Armour have a new wearable this year that works fine with Google Fit (via the UA Record app). It's a tracker worth considering if you're keen on the rest of the Under Armour Healthbox pack or don't want a full-on smartwatch on your wrist.
If you want to get serious about your sleep tracking then this smart light and alarm from Withings fits the bill. An optional accessory monitors your tossing and turning and sends all the data back to the Withings Health Mate app, and thus through to Google Fit.
Xiaomi Mi Band Pulse
If you don't want to shell out hundreds of pounds on a tracker then this wearable from Xiaomi will do the basics for a lot, lot less. Okay, the supplied app isn't the best in the world, but you can get around that by syncing all your data to Google Fit instead.
Best Google Fit apps: Fitness
Adidas Train and Run
You can use Adidas devices as well as the app that goes with them to pass all your stats over to the Big G, should you wish to. The app covers real-time coaching, voice feedback and personalised strength and cardio plans, so it's one of the most complete.
If MapMyFitness is your running app of choice then you'll be pleased to hear that it's also fully compatible with Google Fit, sharing stats on your runs, improvements in your fitness, calories burned and all the other vital statistics supported by Google's health platform.
Nike's had a bit of a patchy record when it comes to playing nicely with Google, so it's pleasing to see the company has updated its running app for Fit. No prizes for guessing that run stats are the order of the day, which Nike's app has always been strong on.
PlexFit for Pebble
Alongside Pebble's latest update to include Android Wear-style actionable notifications on its smartwatch, it also announced compatibility with Google Fit via the PlexFit app, a fitness tracking app on the Pebble store that logs walking, running, biking and more.
The running app of choice here at Team Wareable, Runkeeper covers all the statistics you want to record at any speed from a walk to a full-on sprint. Having all of the key data backed up in Google Fit as well makes the app even more of an appealing choice.
Runtastic is compatible with nearly every app going, so Google Fit support is no surprise (it's good news too for users of the companion running band and Moment watches). The Runtastic Me app can also suck in Google Fit data obtained from other sources.
The running and cycling tracking app is one of the best social fitness experiences you can get, and its data can now be automatically shared with Google Fit. Set up the connection inside the app to see details of your workouts next to your step data and activity logs.
Best Google Fit apps: General health
And... relax. Calm focuses on meditation, sleeping and relaxing to make sure your body is running at its optimum level for most of the time. There are a choice of meditation guides to choose from as well as some premium options if you don't mind paying a little extra.
Cinch Weight Loss
Weight tracking in Google Fit is a bit of a clumsy affair, so use Cinch to do the job for you automatically instead — the app is brighter, prettier and more intuitive than your average weight loss program, though some of the better features do require in-app purchases.
The most obvious option if you're looking to keep tabs on periods and ovulation on Android, Glow is a well-designed app packed with features and has been developed with help from fertility health experts. The Google Fit integration is a welcome bonus.
Instant Heart Rate
You don't necessarily need an expensive chest strap or smartwatch to track your heart rate, because this clever little app can do the job using your phone's camera: it uses the lens to detect how fast the blood is flowing under the skin of your fingertips.
The popular weight loss app has fully integrated with Google's platform so details of your plummeting pounds and shredded stones can be recorded on the dashboard. It's satisfying to see workouts from other apps benefiting your waistline within Google Fit.
Sleep as Android
Sleep as Android is pretty much your only option for sleep tracking in Google Fit right now — Fit itself has only just been updated to accept this type of data, and Sleep as Android will pipe all of your logged slumber times straight into it to combine with your other stats.
Withings Health Mate
The Withings Health Mate app is fully compatible with Google Fit, which means you can suck in a range of fitness data from a variety of devices — smart scales, sleep trackers, blood pressure monitors and more. The app itself is tidy and well presented.
