Two years on and still going strong, Apple's dedicated Health app now works with a growing number of apps and gadgets, so you can 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
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.
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.
Pebble Time Round
Pebble's round smartwatch, like the rest of the Pebble range, works with Apple Health (and indeed Google Fit), so if you want an independent smartwatch that's going to beam your sleep and your step stats to any flavour of smartphone then this is one to consider.
Have a read of our Pebble Time Round review to see what we really made of it.
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.
Withings Aura Connected Alarm Clock
Any bit of Withings kit works with Apple Health (including the incoming Steel HR) but it's worth highlighting the Aura Connected Alarm Clock as something a bit different. This intelligent light wakes you up naturally, senses your movements during the night and helps you to optimise your bedroom environment.
Read our full Withings Aura review.
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.
