Very promessing !

The app gives you a very good overview of your activities during your day and a good sleep analyser.
A fiew glitches but devs are working and releasing updates frequently.
Probably not a long way to have nothing to envy fitbit and co.
Missing networks connexions (runkeeper, withings...) and interactives graphs on ios app, and maybe some help from m7 of iPhone 5s. Is it on the way ?
Anyway, good app, fair price ! Thanks.
