  • Can’t even use app on non iOS 16+ devices

    I loved using this app. Tracking my fasts, activity, and sleeping quality. The fasting timer is really top notch. Very disappointed to see that the company decided to only offer the app to devices running iOS 16+. My device is on 15-something, but I can’t even USE the app, even though I had used it on pre-16 versions just fine before. I can understand no longer providing help support for older devices, but removing access entirely is a crappy move. My device works just fine for what I need, but now I need to buy a whole new device to meet your arbitrary decision? Shame.
  • Great App - Account Erased

    I love this fasting app. Been using it for years now. I’m a Zero Plus subscriber and some how my account and data was erased. I opened the App, had to sign back in, when I did, it said, Welcome as a new member. I clicked restore purchase, but it simply has me as a new account. All my years of fasting and completed challenges are gone. Starting anew in 2025. Truly!!

    I had read great reviews about this app and I liked that it was actually free, or so I thought. The second I created my profile it tries to force you to pay for a subscription and you can’t x out of it. Just another money racket.
  • Not free!

    As others have said, this app is not free and does not have the option to only use some features or have ads for a free version. You don’t find this out, though, until you have given the app a lot of detailed information on yourself. What a scam! I just want somewhere to track my daily fasting times, but this is not that app!

  • Misleading

    I wouldn’t have wasted my time downloading this app if I knew came at a cost.
  • Premium ads insanely annoying

    I never leave reviews for apps but I found this app so freaking obnoxious with a banner and pop up every time I opened it to get me to pay for premium that does very little other than a couple extra status indicators and videos you can find on YouTube. I almost paid for it tbh, but found the harassment so obnoxious that it left a bad taste in my mouth and I switched to another app.
