Among other improvements and fixes, support for Apple watch has been the most significant feature of the recently released iOS 8.2 update.
New in this is the Activity app for viewing fitness data and achievements from Apple Watch (pairing with Apple Watch is required).
The Activity app provides visual snapshots of your daily activity with three rings such as Move, Exercise and Stand.
The Move ring shows how many active calories you have burned, whereas the Exercise ring shows how many minutes of brisk activity you have completed, and the Stand ring shows how often you stood up to take a break from sitting.
The Activity app is a stock app in iOS 8.2, but it will remain hidden until you connect to Apple Watch, confirms developer Hamza Sood.
iDownloadblog has shared a guide using which you can unlock the Activity app on iOS 8.2. Also, you do not need to have a jailbroken device to unlock this app on iOS 8.2, and it can be done by adding a couple of plist files.
