HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (5380 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. 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.

★★★★★Oct 17, 2026

was great a few years ago but has now become hard to use and impractical

★★★★★Oct 17, 2026

I used to use this a few years ago. I logged in, opened the app, and instantly got hit with a popup to subscribe to premium with no way to close it. I'm never going to use this again because I literally can't without subscribing.

★★★★★Oct 15, 2026

I WAS CHARGED DESPITE I HAVE UNINSTALLED AND UNSUBSCRIBED BEFORE THE FREE TRIAL! PLEASE PROCESS THE REFUND ASAP! PLEASE RESPOND TO MY EMAIL

Intermittent fasting also encourages healthier, more conscientious choices around what you eat. Finally, intermittent fasting enables your body to tap into its fat stores for fuel so that you burn fat faster.
