Testimonials
Having done intermittent fasting without the app before, I’m happy I’ve found it. The interface is great, the facts are helpful and so far have been feeling motivated and loving its gentle nudge.

Easy to use and customize. The timer is simple, which I like almost as much as the privacy of my information (meaning there is no social media like attempt to connect with others who are fasting.)

Very easy to start fasting or to adjust it if you forgot to start it right at the moment. Also, the alerts and reminders make it very simple, and it’s great to be able to see a graph chart it against bodyweight. Does exactly what it needs to do, without being over-complicated.

A fasting app doesn’t need a ton of complicated features. The app will remind you when you’re close to reaching your goal, but you can easily go past the goal or stop early if needed.

This app shines for its simplicity and also its versatility! I’m new to fasting (few weeks now) so I can’t always make it to a “set time”, but that’s ok! You can set a goal (16hrs for me) and then click start when you’re done eating.

Seeing my fasts on a weekly timeline has really helped me see the overall picture of how I’m doing and motivated me to beat my best times.

Never been into intermediate fasting until I tried the free week on this app. It definitely motivates you and explains generally what your body is going through, like burning fat instead of carbs and your sugar going up or down and how that affects you. It’s an amazing app and they continue to update it regularly ! Have lost 20lbs doing fasting so far! From 190lbs to 170lbs.

The most awesome part about the process is that it explains what’s happening to you as you go along. You want to push yourself to the next phase every time. I think it also makes you eat less by focusing on what’s happening to your body. The daily tips are also awesome and well presented.
