Have questions?
Can intermittent fasting help with weight loss?
Absolutely! Intermittent fasting naturally reduces how often you eat, inadvertently leading to consuming fewer calories. It also promotes mindful eating and encourages healthier choices. Additionally, fasting enables your body to tap into its fat stores for fuel, aiding in weight loss.

I've been using this app for a couple years, and have loved it. I agree with many of the others that the loud ads are annoying, but I just close out as quickly as possible to shut them up. My problem is, I went to break my fast and the app only partly loads. I updated it and it still won't load my fasting history and says I have it set to 20hr fasts when I have it set at 16hr fasts. Not sure what is going on. Editing to add, I logged out and now I can't get past the white fastic screen.

Just reduced my rating to two stars since it still provides the intended purpose, but the ads have gone too far now. I know they need revenue, but I don't need a loud full screen ad when I update my schedule while at the office. Now, they are pushing a dialog to promote their AI every time I start the app. Again, you want to earn money, offer a one time upgrade to premium (not monthly). At this point, I'm trying to find an alternative, or I'll just schedule daily reminders on my calendar

The app was once really great. However recent LOUD FULL SCREEN ADS are not. Fastic can deliver ads in much less intrusive way and still keep it "free". I suspect there is a lot of competition by similar apps now and Fastic wants to get as much revenue as possible while they can. I was able to find a alternative app to track my times without much effort. Goodbye Fastic, you were once good. No hard feelings but we must part ways, please donate my frosties to a good cause. Uninstalled.
