User reviews

Broken

Daily activity will stop if you move off app to play music or any other source. It is horrible for tracking time for the day.

Phone calls

I love the app, but I do wish that when I answered a call it wouldn’t pause. I always forget to start it back and lose time.

Not so bad so far

I just started using this app. So far so good.

Definitely not for a couch potato

Says couch to 21.1k but first workout is a 40 minute run. Seriously!!!

Useless

Rubbish app
