I’ve used Zero daily for 11 months and it has helped me keep to my fasting goals. I love the simplicity of it, the colors, reminders, the widget! I enjoy looking at my calendar view to see how I’m doing over time. I love that I can sync Zero with other apps. Zero developers obviously love their product because they keep improving it all the time. ❤️?

I signed up for the $5.99 subscription and was charged the yearly amount. When you go to support for a refund (pain in the a**) it takes you to Apple support to see what is wrong with your phone not the app. Grrrrrrr

Absolutely love this app even though I had been doing Time Restricted Fasting on my own for a month, after changing to One Meal A Day I thought it would help to keep track of my meals, time and moods. The app keeps me on track, the articles are super helpful and it’s simple to use. Highly recommend it!
daz it!
I just started using the app really nice. But I hate that it’s restricted to some features.

You put in your info and click on start fasting and nothing happens, even when you click on other options nothing happens. Try to restart the app and put in your into till you get back to that page and everything seems to freeze again. Disappointing

Promise of trial with year subscription, but charged $70 immediately, with no apparent time for trial. I loved the app until now. I cannot abide or endorse such deception.

I like Zero and I use it. That said, it needs two major improvements: (1) The UI is confusing. Text is too small, non-essential info clutters the app, far too many options are displayed. Keep it simple! And make it easier to read at a glance! (2) The entire fasting paradigm is backwards. No one cares about when to start/stop fasting… we care when should we start/stop EATING. Flip the paradigm and this app will be the best!
