The app is a nightmare to navigate. I can't figure out how to set schedule for fasting and to set up notifications, so I'm reminded to start and end my fast timer. Those seem like very basic functions of an intermittent fasting app and maybe they exist but finding them is not easy. I don't understand why we can't just make an easy app for intermittent fasting.

"You already have a fast saved during this time period" Yea if you want to fix this, error bug that doesn't let you edit the time period, the only way is to uninstall and re-install the app. Apps are supposed to be intuitive and convenient. Having to uninstall and reinstall is not convenient. Thus making it easier to just keep track on my own. I don't normally write reviews, just ones for exceptionally bad apps with quirky bugs like this.

Excellent app, for beginners especially, because it teaches you why fasting works, why you should eat healthier, and all about metabolism. The daily lessons are interesting and informative. I like that there are daily tasks to complete. The social circles are good to have if you aren't into FB, however, don't expect a lot of comments on your posts. I don't care about that, but some might. But there are several groups you can try if you're into that. Very easy to use, and visually appealing.
