This app helped me take control

I was fasting on my own without an app for about a month before I found this app. I was writing down my fasts on a calendar and it was really hard to kinda keep track of when and where of everything. When I found this app I tried it for the basic version for a few days and I really liked the features of scheduling out my week and being able to plan ahead. I did decide to do coach and I’m super impressed with the new things that were unlocked! This app has been making it so much easier for me to set my fasts around my work schedule (I work at different times each day, so I wouldn’t be able to eat at the same times each day). I really like being able to see where I am at with my fasts, and how it’s working within my body! It’s super interesting and being able to know what exactly is happening helps motivate me! I also really like that this app is more than just a fasting timer. It allows you to track your fast, track your water intake, track your weight, track your body measurements, and the challenges that it loads up during your week keeps the fast fun. I totally thought that this would be all smoke and mirrors but seeing the physical results, it’s one of those things that, if you feel like you have tried everything, you can’t stop yourself from yo-yoing, and you’re looking to put in the hours, this is definitely for you, and this app is worth it!!!

Great App & Very Helpful

So far so good I just started doing intermittent fasting and when I typed it into my browser to learn more this was the first app that came up. I like that it not only helps with keeping a schedule it also gives you an option to pay for a coach or not (a lot of apps don’t give you a choice you either pay for the service or you don’t use the app lol). Granted most of the app isn’t open unless you pay for a coach, but for what I need it for and the basics are all free so if you’re like me you can at least use it without having to pay for a coach and whatnot. The other thing I really like is during fasting it has a list of everything you will go through after whatever time frame you’re at. It tells you what your body is doing at this particular milestone (4hrs, 8hrs or whatever) and how you can fix it. That alone is helpful because if you’re just starting out it’s refreshing to see what you may be experiencing at that particular moment. All the other stuff like keeping track of water intake, weight and other fitness stuff is cool too but it’s kind of expected.

Helped me lose +30lbs

This app is perfect for people who are new to intermittent fasting. I moved away to college and ended up going from 132lbs to 165lbs at my heaviest.

I tried other diets that failed miserably and made me gain all my weight back instantly, and never found a workout routine that I consistently stuck to. Intermittent fasting was admittedly hard to stick to at first, but with enough persistence and getting myself back on track I was able to get my weight down to 130lbs. Intermittent fasting has “reset” my stomach or rather how much food I can intake in one sitting. You should be warned that in order to see real weight loss results, you have to pair intermittent fasting with healthier eating and moderate to light weekly exercise.

I have been using this app for two years now and have never purchased anything on this app, I was able to lose all the weight by just using the free services provided. I would recommend this app to people who are brand new intermittent fasting or people who are seasoned to fasting.
