"I tried a handful of fasting apps for my intermittent fasting life and none of them was the right one for me. I then tried this one and it’s been the one I have stuck with. It’s simple yet complex in a good way. Great app. Recommended!"
"MyFast is the best intermittent fasting tracker and weekly scheduler app available. It quickly guides you through the overall concept of fasting and will help you completely manage your fasting and eating windows. With over 200,000+ fast trackers, we are the most complete and trusted IF timer."
"Favorite app for tracking fasting / weight loss. I’m terrible at counting time and that’s the whole reason I have this app. I can set my goal by deciding I want to do an 18 hr fast and it tells me when to stop fasting. I can edit my goals on a daily basis when starting IF, OR set up a regular schedule. You can track water intake and weight loss and easily compare weight loss to fasting length on the same screen. Minimal, noninvasive ads and no required ‘plans’. I recommend this to everyone!”

What Is Intermittent Fasting?
What usually comes to mind when most people hear of Intermittent Fasting (IF), is that it is just another crazy fad diet to lose weight with little effort. However, it isn't a diet at all, but rather an eating pattern. It’s not what you eat, but when you eat it that is important.
Depending on what type of fasting you schedule, you generally will have a time window where you are allowed to eat all the food you want. As soon as that window is over though, you don't eat ANYTHING until the window comes up again. For example, a common approach is 16 hour fasts with an 8 hour eating window every day.
There are dozens of different type of fasting diets, and with MyFast you can utilize any plan such as:
16/8 - Lean Gains
5:2 - Eat normal for 5 days, and IF the remaining 2
20/4 – The Warriot Diet
24/0 – Full Day or Alternative Day Diet
Alternative Day Diet - (every other day you will be fasting for 24 hours.)
Any other zero calorie fasting plan you can think of is possible
MyFast can be used free of charge, and within the app, you can choose to buy a subscription. With Subscription you can all premium features.

Perfectly Simple and Customizable, Best Fasting App

I must've downloaded 10 or more different fasting apps with tons of bells and whistles, yet not a single one has the simple functionality of MyFast, thank you! You can adjust duration AND start time, can measure fasts longer than 24 hours (why is this even an issue with other apps?), love it, don't need anything else. I'm working the Catalina Wine Mixer this weekend and will show it to all my buddies.

Not great.

If you’re on schedule mode, you can’t press start or stop fasting when you actually do. Just works like a clock telling you whether you should be eating or not. In the manual mode you can press stop/start fasting and it’s more realistic, however it doesn’t store your history whatsoever and if you transition from schedule to manual, the app is very confused and just assumes you’ve been eating the whole time since forever ago.
I needed a simple free app without reviews, etc, but this one is no better than your phone clock/alarm/timer. Used for a few days, looking for a different one.

Simple and customizable

I downloaded all of them and this is the best simply to use fast timer that goes over 12 or 24 and is customizable without paying! Good job to the developer for putting the customizable option and let you edit the start time if you forget to start the clock or were too busy to do it. Thinking ahead is the way to go!
