I really can’t relate to all the comments saying it’s not for free. They give you a free trial, learn to read. Super happy with the app, love the new timer 🔥

Lacking

2 stars for core functionality. - 2 stars for the on obnoxious, predatory subscription ads. - 1 star for missing Shortcut connectors (cus not using the widgets would cause you to miss premium subscription ads)

I used to have the free version. I have now made a new account to re enter all of my data but now there is a big screen popping up telling me to pay the subscription and I cannot close it.

Have been using Zero for years and love how it has advanced. The only thing I'd like to have is more stats on meals and mood. Esp mood logs just disappear 🫥 Just tiny complaints for an overall fantastic and educational app! Well done, keep up the good work!

Why is this app forcing me to Buy a subscribtion?

I used to have the free Version and redownloaded the app. Now a big window pops up whenever i open the App and i cannot close it.

Super app!

It‘s a very nice app. A little bit of a bummer that the weight graphs longer than a week are not included in the free version (the iOS Health app features one as an alternative). But for the fasting it‘s a neat support!

Synchronisation just not working

Stoani on

If you run that app on more than one devices, be prepared to constantly change and edit fasts!

ui and ux quality droped!

shimakk on

Austria

i used to like zero alot but since the latest design change and face lift i feel the whole app started to be pool of advertisment and money trap instead of helpful tool for people. The poor UX and So many wrong and misuse of UI elements droped the app quality hugely. I hope they would think about of going back to those times where the simplicty of the app was made it one of the best apps. I couldnt resist anymore and therefore unistall it and will use something else.

Since the last update
