App helps, but has major bugs

kommaardoor64 on

Netherlands

First of all, the app helps a lot with my fasts. So I’m very postive. But considering the price, the bugs it has are not acceptable. App runs in less than 60fps, I suspect because of the ‘ai’ chatbot visuals. Also when you press a notification like ‘click to see your week in review’, nothing happens. No week in review. Other notifications only open a website, not the app.

Started using this app years ago, loved the user friendliness. Over the years the app has gotten worse, adding annoying notifications, pop ups, and other unnecessary things. And now they’ve made payment mandatory. Bye Zero.

Scammy

You have to pay a subscribtion to use the app

Great app (if you pay) but pushy

Zero is a great app and I have been a subscriber in the past. I know merely use the app for tracking fasting hours. But it's pretty annoying how hard Zero pushes you towards becoming a paying member. It makes me not want to.

Not usable

You can’t use the app without paying 79 euro.

Helpful app, but recently drained in “subscribe now”

The app itself is pretty useful, I recommended it to several people, but every evening/morning I now have to click the 40% off advertising away before I can press start/stop. Another great app commercialised oh and… uninstalled.

you have to pay??
