5 stars: I heard about Zero from a group of online fitness acquaintances. I was not familiar with intermittent fasting, but I was intrigued. This app makes tracking your fasts so easy. I do not have anything with which to directly compare it, but as far as tracking apps this one of the best!
3 stars: I like the app before the update, now I had to tap the fast goal a lot to get to edit it and then the hour fast are overlapped. I liked the old version where I can easily see the elapsed time below the remaining time but now I had to click remaining time in order to see elapsed time. Anyway, overall still good job and still love it 👍👍
3 stars: Quite buggy - sometimes upon opening it, my fast is overwritten and I lose all progress. Some of my fasts are saved as duplicates e.g. 2x 16hr fasts on June 28 🤔. Useful aside from the bugs. Update October 2020: the same bugs have been persistent for about a year. The app is slow and laggy. Every time I hit \
5 stars: Great tool. I didn't think this was going to help, but when I think about stopping my fast I remember the countdown is ticking. Not sure why, it makes me want to reach that final count. This seems better that randomly stop, and tracking my mental state as I fast helps me to recognize when I hit a slump. This helps me push forward.
4 stars: The timer is really convinient, but the notifications need some work. I'm sick of getting notifications on the middle of the night that I'm halfway through my fast. Had so...
