Fitness Challenge

Pursuing your fitness goals is fun together with friends. Challenge your friends for daily activities and see who's leading. You can use any fitness trackers such as Apple Watch, Fitbit etc. Sync the tracker with Apple Health / Google Fit. The app reads daily activities from Apple Health / Google Fit.

Features
