6 best Intermittent Fasting Apps in 2020
for beginners and advanced

Do you feel confused about fasting and eating windows when doing Intermittent Fasting?

Thinking of starting Intermittent Fasting but not sure what time you should start or stop eating?

Maybe you’re looking for the best way to track your fasts and lose weight?

Yes, I get you – I felt the same. 

Luckily there are a bunch of intermittent fasting apps (a.k.a. time-restricted eating apps) available that come to rescue.

In this fasting app review, I will share with you what I consider to be the 6 best intermittent fasting apps as of 2020.

Top Intermittent Fasting Apps Review: Criteria

When doing research on which apps to review, I went to the app stores, Google, Reddit, Quora, friends, and Youtube and chose the 6 best fasting apps below as my favorites.

I’ve tried to look for more fresh, perhaps a bit less known (but still very good) apps, but you’ll recognize some of the most downloaded ones as well.

Also, the first 4 of my chosen apps were happy to collaborate and make this review possible, so big thanks go to them.

Then I looked at the following criteria:

  • Features
  • User Experience 
  • User Interface 
  • Premium options

Note: All data regarding functionalities and price is as of February 2020. 

Top 6 Intermittent Fasting Apps

1. DoFasting*

Main features:

  • Personalized to your weight-loss goals
  • Easy-to-use Fasting Tracker
  • In-app meal plan with macros and recipes
  • Workouts plan with video-demos
  • Weight Tracking

PRICE: From $1.25/week to $2.50/week

The first fasting app on the list is called DoFasting. Available on both Android and Apple devices, DoFasting is one of the best intermittent fasting apps I’ve tried. While most of the fasting apps are just fasting trackers, DoFasting is really sort of your personal intermittent fasting assistant. 

These are the main reasons to get DoFasting app:

  • Personalization. It all starts with a short quiz right at the beginning, which tailors the app to your needs and goals. It will ask you about your level of fasting expertise, eating preferences, fitness level, and a few other questions.
  • Fasting Tracking. You can choose the fasting schedule you’d like to follow from 6 available presets based on difficulty as well as set your eating window times.
  • Personalized meal plans. Based on your answers on the sign-up quiz, you get your daily caloric intake. It also includes recipes and macros that make following a meal plan really easy. A super handy feature if you want to improve what you eat, not only when you eat.
  • Workout Plan. Based on your fitness level settings, you get workout suggestions with the full exercise plan and video demos. What’s great is that exercises are short and can be done in a home environment.
  • Tips. DoFasting has a section called ‘Tips’; that is what it says – it gives you tips and knowledge on intermittent fasting. Lots of knowledge that is easily accessible at all times. Pretty standard, but really handy feature.
  • Weight Tracking. Finally, you can track your weight, fasting and workout history in your PROFILE tab. I like how visual it is, shows your current weight and how much weight did you lose.
Also – thanks to this close cooperation while undergoing DoFasting app review, I was able to get some insider knowledge that the DoFasting team is working on a major app uplift. From what I’ve heard, it’s really gonna be one of the must-have weight loss apps in 2020.

2. LIFE Fasting Tracker*

Main features:

  • Flexible fasting tracker
  • Advanced tracking features
  • In-app community – Circles
  • Knowledge Base on Intermittent Fasting
  • Feed feature for sharing & following others

PRICE: Free (additional Premium features available)

Last year when reviewing best intermittent fasting apps, I included LIFE Fasting Tracker in the ‘up and coming’ category. This year I’ve decided to put it in the Top 6, because of all the extra features they added and a huge community they managed to build.

These are the main reasons to get LIFE Fasting Tracker app:

  • Flexible fasting tracker. When you open the app, the first thing you see is a very clear fasting tracker. What’s great is how flexible setting the fasting time is. Just press the + and – buttons and easily set the number of hours you want to fast that day.
  • Various tracking features. Besides fasting, you can also log your weight, waist circumference, glucose, and ketones. Probably one of the most advanced trackers as well!
  • In-app community. Another feature that makes this fasting app really stand out is called Circles. It’s basically an in-app fasting groups that allows you to see other users fasting, their overall fasting statistics as well as send them a DM. You can join one of the 60k existing circles or create your own with the people you know. I’ve created our own circle called 21 Day Hero Fasters – feel free to join this one!
  • Collection of intermittent fasting articles and videos. Under the ‘Learn’ tab, you will find the ‘Learning Library’: plenty of science-backed information on intermittent fasting and other similar health topics and how to make this journey more successful.
  • Feed feature. You also have your feed, which will fill up with posts from your fellow fasters in your circles. You can post your own updates, interact with others and simply follow each other’s journey. One of the key components needed to achieve the results you’re looking for!
  • Your fasting statistics. In the ‘Profile’ section, you will have your fasting statistics all in one place. It even shows the hours in ketosis part, which is basically the part during which Intermittent Fasting does its magic.

The main version of this intermittent fasting app is free, but it also offers premium services like biomarker blood tests and real-time health coaching.

Finally, little birdies from the LIFE Fasting app told me that soon they will have a scale integration, which will make weight tracking automatic. Also, you can use the login of LIFE Fasting app to their other app called LIFE Extend, which helps you to track a lot more than just fasting.


3. Fasten*

Main features:

  • Custom fasting presets
  • Fast with Friends (coming soon)
  • Weight Tracking (with reminders)
  • Hydration tracking (with reminders)
  • Mood Tracking (with reminders)
  • Integration with Google Fit
  • 200+ low-carb recipes

PRICE: Free (Premium features for $9.99/year)

One of the underdogs in the game of fasting tracking apps, but with many unique features, I can see it becoming one of the most popular apps in the near future.

These are the main reasons to get Fasten app:

  • Fasting on your own with custom presets. You use the fasting tracker to fast on your own and choose from 8 different protocols, including Circadian, OMAD and “custom” up to 7 days.
  • Fast with friends (coming soon). One of the features that the developer of Fasten was really excited about is called ‘Fast with Friends’, which will introduce the concept of Live Fast. Soon you will able to fast at the same exact time and for the same duration together with your buddies/other app users and hold each other accountable. Really excited to see this coming and try it out!
  • Weight tracking. Weight is part of your tracking setup too – just set your current weight in pounds or kilos and log your weight as often as you like.
  • Tracking of water intake. You can activate hydration tracking, which will help to ensure you stay hydrated. It can help you track your water, tea and coffee consumption and will also remind you when you didn’t have enough. Not drinking enough water is one of the most common intermittent fasting mistakes, so this will help you to avoid making it.
  • Mood Tracking. Tracking your mental health is as important as physical. With the mood tracking, you can keep a log of our emotional state during the fast, so you could draw some conclusions and make decisions.
  • Google Fit integration. The app also integrates with Google Fit, to have your fasting data synced with your physical activity. Really handy, because weight loss is a balance of a great diet and proper physical exercise.
  • Access to 200+ low-carb recipes. Super useful feature and what’s great about it is that you can only access them during your ‘eating’ window, so the pics of a perfect cheese-cauliflower pizza doesn’t make the fasting any harder than it should be 🙂

Fasten is part of the Welzen App bundle that includes apps like Welzen for meditation and Waten for hydration tracking. The latest update has made all 3 apps integrate with each other seamlessly.

Simple Intermittent Fasting app logo and review

Main features:

  • Personalized fasting tracking
  • Additional tracking options
  • Simple & easy to use
  • Guidance & tips on intermittent fasting

PRICE: Free 7-day trial and then from $2.99/month

The other fasting tracking app that I really love is called Simple Fasting Available on both – Apple App Store and Google Play Store. Simple stand out among other best fasting apps with the number of great features and their strong focus to help you build a foundation for a healthy life.

These are the main reasons to get Simple app:

  • Personalization. Once you open the app for the first time you’ll go through a short personalization setup. You are able to set your fitness level, height and weight measures, goal weight and finally choose the type of fasting you’d like to go with. All of this will be reflected in profile stats, personalized insights, and weight tracking.
  • Extended Tracking. It’s amazing how many things you can track with Simple. Fasting, weight, fluid intake, moments of hunger and even meals you’ve eaten. One of the most unique features I’ve seen is being able to track body progress by taking pictures of yourself and being able to compare how your body changes over time. It all gets tracked in your personal fasting journal which is an amazing way to keep a record of your journey.
  • Simplicity. They really stand behind their name. I’ve been using this app for a couple of weeks now and I must say that everything is very straight-forward and clear. The usability of the app is one of the best I’ve seen. They have some nifty design solutions as well, which makes it easy to reach a number of important features with just one click. The average app store rating of 4.8/5 definitely proves that other users enjoy it as well!
  • Guidance. If you’re a beginner in a fasting world, you’ll love this app. App tells you when to fast and when to eat and you get help at each step of the way. And it doesn’t just tell you what to do but also explains WHY you should do it or HOW to understand your body better (e.g. emotional hunger vs. physical hunger).
  • Insights. It’s not the usual ‘same for all’ type of info. Part of the insights you see in the app are completely tailored to you. And the best part is that they change over time to help you gradually build better eating habits and get rid of those that don’t serve you well.
