Over two years on and still going strong, Apple's dedicated Health app now works with a growing number of apps and gadgets, allowing you to feed in and read data in all kinds of ways.
The main aim of Health is to provide a single point of reference for all your aggregated health and fitness data, and so the more third-party services you can plug into it, the better. Info is also captured via the motion co-processor nestled inside your iPhone, and the integrated sensors in your Apple Watch.
Working out which gear and apps work with Apple Health isn't always easy, so we've done the hard work for you to come up with a comprehensive and current list of the best options out there.
Best Apple Health compatible devices
Apple Watch Series 2
As you would expect, both the original and follow-up Apple Watches work with Apple Health — it would be a big surprise if they didn't — so if you're in the market for a wearable that seamlessly syncs activity data back to the built-in iOS Health app then that's one more reason to buy Apple's timepiece. The Series 2 does have one major advantage over the Series 1: It's waterproof.
Take a look at our in-depth Apple Watch Series 2 review.
Misfit Shine 2
Misfit's budget tracker device is actually a lot more advanced than its plain exterior might suggest. The Shine 2 (like its predecessor) logs steps, different types of activity and sleep, and can feed all of this data back to Apple Health as well as the regular Misfit app.
If you want something in a slightly different style, the Misfit Ray works perfectly well with the Apple Health app too.
Check out our Misfit Shine 2 review.
Wahoo Tickr X Heart Rate Monitor
A chest strap monitor is still the best way to measure your heart rate, even if it's pricey, and this premium model from Wahoo has the benefit of syncing seamlessly with Apple Health for you. 16 hours' worth of data can be stored between syncs too.
Have a read over our full Wahoo Tickr X review.
Reddit 3 Sleep Monitor
Apple purchased Beddit, which may be the ultimate endorsement of its products. The Beddit 3 Sleep Monitor is a favorite at Wareable, and it's easily one of the best sleep trackers you can buy. You just slip it under your sheets and sleep away, using the companion app to handle all of that data.
Xiaomi Mi Band 2
Xiaomi's latest wearable comes with its own stats app but you can just as easily sync it with Apple Health as well, and if you want a basic wearable to go with your iPhone then this is one of the best value options available at the moment... if you can get hold of it.
Check out our detailed Xiaomi Mi Band 2 review.

All about the apps
It's all right there in the name. AutoSleep automatically tracks your sleep. It is best used alongside your Apple Watch, but once you've got it all paired up you really don't have to worry about a thing. Well, except for checking how you slept in the app. You can also check your sleep in Health, but it's not as comprehensive.
Best Apple Health apps: The rest
Qardio Heart Health, Weight and Blood Pressure Monitor
If you've got a Qardio tracker to hand you can use the accompanying app (optimised for iOS 10) to log everything in Apple Health. Qardio goes beyond basic fitness to take a detailed look at blood pressure and most aspects of your cardiovascular health.
Requires device, Qardio
A more unusual addition to the Apple Health family, the popular golf app sits quietly in the background monitoring steps, calories, and the pace of your play, while you find new ways to ruin a nice walk. You'll need the premium app to get Health integration though.
