HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (13 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ I struggled the first few days. Then I struggled for the rest of them and now I can regularly hold a four minute plank. Any chance you'd allow self- designed workouts?
★★★★★ Just what I was looking for to build plank stamina.

Fine, fine

Nice Challenge app

I completed the 40 day plank challenge ending with a 5 minute plank. 65 yrs old male. It was tough to finish but got it done. This app is keeping me in the routine and doing the job.

★★★★★Aug 17, 2024
Simple but effective

Does the job

The app does a great job of timing and giving you the goal, but it would be nice if it didn’t pause music every time a round ended
