No editing?

We have to sign up now and we can’t edit fasts anymore. Going to look for a new app :(

Fasting companion

I do full extended fasts, and I’m always alone. This app is a personal cheerleader and companion during your fast. And you get to see that other people on this planet are fasting too—you’re not alone. You can tract your stats, even your mood and see your progress. This is huge for motivation.

This app is a must have for anyone fasting.

It makes a huge difference.

One function I wish this app had was a pop up of the physiological milestones that occur during a fast, ie: Day 2 you are now suppressing the hormone Ghrelin and autophagy is commencing...something like that would be hugely motivating. And I’ve not seen it anywhere.

Love this app.

Was good, once

Hooray, unneeded update to add a pay version. Only reason I chose this app to start with was that it was simple.
