Nudge is a great little app that syncs seamlessly with the Health app that's already on your iOS or Android device, plus other leading health apps and wearables like Fitbit, Jawbone, Runkeeper, Moves, Garmin, Nokia, iHealth and many more. Nudge syncs all these while providing a central hub to consolidate and record all your general activity, sleep and nutritional targets.
A cool new feature of Nudge as of April 2015 is the “Coach” feature that lets you work with a qualified health professional to help you set goals and keep you focussed. Nudge also has a “Clubs” feature that lets you follow the topics that interest you and see all the latest posts right within that clubs feed.
This is an amazing and quite addictive little app that delivers on the promise of one central place for all your health and fitness data.
