No matter which diet you follow – from Paleo to Keto – or even if you don’t have a specific eating plan, intermittent fasting can have some serious fat-burning and gut-healing benefits. Intermittent fasting itself is not a diet, but rather a lifestyle where you only eat during a specific time window.
There are different daily time windows to choose from with an intermittent fasting lifestyle – including 12 hours, 10 hours, or 8 hours. Or, there are patterns like one meal a day (OMAD), every other day fasting (fast one full day, then eat normally the next), alternate day fasting (36 hour fast, 12 hour feed), and the Warrior Diet (20 hour fast, 4 hour feed).
Without getting too sciencey, a daily fasting cycle can balance the fat burning hormone leptin by syncing your body clock with your circadian rhythm. When you are constantly eating day and night, your body has a tough time with the leptin signals, and you can end up feeling hungry even though you have plenty of energy stored. When your body gets the leptin signals, you feel satiated.
There have been numerous studies about the benefits of intermittent fasting. But, instead of getting into all of those details today, I’m going to assume that you have already read about those benefits, and now you are looking for the right tool to help you make the transition into the intermittent fasting lifestyle.
You’re bound to find an awesome intermittent fasting calculator in this list.
1. BodyFast

Available for both Android and iOS, this app has a free option, or you can upgrade to a coach subscription for $1.35 per week. The free option includes:
- 10 different fasting plans like 16-8 or 5-2

This app already has five million users, and the reviews are overwhelmingly positive. It is a simple-to-use app that focuses on the eating windows, so if you are wanting to get details about calories and macros you should download a companion app like MyFitnessPal.
2. Vora

The most popular intermittent fasting calculator on Reddit, Vora is available for Android and iOS. This cloud-based fast tracker supports different types of fasts, but you do have to register before using this free app. Once you get that out of the way, you will have access to the fasting tracker.
The tracker allows you to monitor your fasting progress every day, and the app connects you to other users for support, and to exchange tips and ideas. This would be a great option if you’re using it with a fat loss system centered around IF.
3. Zero

Created by Digg co-founder Kevin Rose, this app is available for both iOS and Android, and it has a killer 4.7 rating on both the Apple AppStore and the Google Play store.
Zero is a simple fasting tracker used for intermittent, circadian rhythm, and custom fasting. Once you choose your favorite fasting protocol, Zero will track your ongoing progress and you can export your data to a spreadsheet for complete control.
Zero supports the 16-Hour Intermittent Fast which was popularized by Hugh Jackman and Dwayne “The Rock” Johnson as a fast to shed pounds, and it also supports Circadian Rhythm Fasting. With this fast, participants are encouraged to fast 13 hours per day, starting each fast at or before sunset.
This app also supports 18:6, 20:4, and 36-Hour fasts, and there is a custom fasting option.
You can log previous fasts that you might have missed, see all your fasting history in the Journey screen, check all of your fasting stats on the History screen, and even keep track of your fasting streak.
4. FastHabit

Whether you’re just starting out or taking your fasting program to the next level, FastHabit’s features will keep you consistent and motivated so you can tame your cravings, shrink your love handles, and get healthy.
This app is free and only available for iOS, and it is customizable to work with all fasting programs and your preferred tracking views. FastHabit has reminders and notifications, can sync with an Apple Watch, and allows you to see your stats and progress.
5. LIFE Fasting Tracker

Created by LifeOmic, this intermittent fasting calculator is simple and easy to use to keep track of when and how long you fast. One of the features users love the most is the visual graphic of when you go into fat burning mode using your stored body fat.
The Life Intermittent Fasting app is free and allows you to track your progress on any fasting schedule. You can set the start and end time for each fast, and there’s a clock that counts the minutes and hours you have fasted.
This app keeps track of how many total hours you’ve fasted and your total number of fasts. It also monitors your progress and allows you to connect with your fasting friends on the app for support.
6. MyFast

MyFast is a free app available on both Android and iOS that offers unlimited fast lengths and the option of a 12-hour or 24-hour clock format. It also offers pop-up notification when your target fast is completed, and it allows you to add, edit, and delete completed fasts.
While the rating is high for this app, the only negative is that it doesn’t allow you to customize your fast. Instead, you have to use one of the options, the most popular being the 16-hour fast.
7. Fitstinct

This option is not an app, but I wanted to include it because it has a handy calculator that calculates your meal timings, macros, and supplementation details inside your fasting window. Once you enter all of your fasting info, the Fitstinct calculator will generate your specific results and email them to you in PDF format.
