my own fasting companion

So far so good, tutorial videos are super helpful and concise I need to get to know all the other features but that’s on me

My fasting companion.

My fasting journey, my lifestyle change and weight loss would have been unachievable without the zero App. I lost 20kg in 4 months and I have stayed very close to the app for a year and a half. I have named the App my irreplaceable companion.

Pretty buggy! A disappointment so far.

Can’t manually enter data anymore. Says it’s syncing with Apple Health, which I don’t want and never connected to. Support is ineffectual other than to say that the bug has been reported. It looks like I bought an expensive timer program.

Won’t save weight

I’ve used this app for months with no problems. Suddenly this morning it won’t save my newly logged weight. Frustrating. iPhone 12, iOS 14.4.2

This is NOT a free app!

When you open it, you get to a screen where you have no choice but to subscribe. Janky, to say the least!

Fasting with ZERO

This is my first time to do a “real” fast. I love it because ZERO leads me every step of the way. I envision using this app everyday for a very long time. ZERO encourages me and keeps me motivated. Great guidance and information from the messages and videos. I’m fasting to lose about 4 pounds (not a big deal) but primarily to improve my overall health and stamina. By the fourth or fifth day it all clicked. I feel fantastic and my clothes fit again. Yep!! I’m going to make this my lifestyle ❤️Thank You to everyone at ZERO!!

Not for beginners

This offers very little information as far as diet is concerned. It’s basically just a timer. There are articles and videos for your perusal, but nothing that can’t be found on google. I overpaid for an app that is basically just a timer. It should at least include nutritional information and tracking.
