That Health feature Apple unleashed on every iPhone that uses iOS 8 is an odd and confusing beast that doesn’t appear to do much on its own — but that doesn’t mean it isn’t incredibly useful.

Its true value shines when synced up with other health and fitness apps, creating one well-being super-app. Through its underlying HealthKit software, you can get an overall health profile that shares data across apps. So your workout recommendation app can refer to info on your weight, sleep patterns, and blood pressure to give the best results, or your meditation app can check your stress levels and adjust its settings accordingly.

The entries below prove that Health is anything but worthless. If you want to explore more, just search in the App Store for apps compatible with the Health app, wait for them to ask permission to sync with it, then open Health and select the “Sources” tab to determine how they send and receive information. Different apps may have different settings, so play around to make sure you’re getting everything you can out of them.
