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.
  • 20 different diet types. Combine Intermittent Fasting with Keto, Paleo, Mediterranean, and any other diets to reach maximum results; DoFasting has more than 20 different diet types available within the app. 
  • Calorie tracker. Easily log calories of each meal consumed. Tracking your calories has never been easier!
  • Step tracker. Track your activity (steps), set goals, and see how many calories you have burned
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 2021.

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 services available)

Last year when reviewing best intermittent fasting apps, I included LIFE fasting app in the ‘up and coming’ category. This year I’ve decided to put it in the Top 10, 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 LIFE 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.

FAQ on intermittent fasting apps

Which is the best free intermittent fasting app?

It’s all the matter of what you’re looking for. From my experience, Life Fasting Tracker is definitely one of the top fasting apps overall. It is completely free to use unless you are looking for additional services, for example, personal coaching sessions or blood tests.

But feel free to scroll through the list and find what would work the best for you. Almost all the apps on the list have a free version with all the necessary features to satisfy most intermittent fasting fans. Even if you opt for a premium version, it won’t cost you much more than a cup of coffee.

Which would be the best prolonged or water fasting app?

To track your water fast or extended fast times, any fasting app will do the job. All of them either have various fasting schedules to choose from or manual fasting tracking where you can add your own eating and fasting windows.

A handy feature for water fasts would be hydration or water intake tracking. My favorite apps like DoFasting have a feature to track your daily water intake and these apps offer various fasting schedules, which would make them the perfect water fasting apps.

How does Life Fasting app work?

Overall, Life Fasting App is easy and straight-forward to use and has all the necessary features you need to do intermittent fasting. Plus, their fasting tracker is the most flexible and easy to use I’ve seen – you can fully customize your fasting and eating times.

The one feature that makes Life Fasting Tracker stand out is the in-app community circles. You can join various groups of other like minded-people doing  fasting (like “First time fasters”, “Keto Fasters” etc.) or create a new group to meet new people or add your IF friends.

Life Fasting Tracker is also very useful for people doing Keto – you can log and track ketone and glucose levels and even see hours spent in ketosis. These features I haven’t seen in any other free fasting apps.

As I said, Life  fasting app is free to use, so you can try it out yourself and see if this is the fasting app you’re looking for. You can try it here.

How does Do Fasting app work?

After trying DoFasting, I have to say it’s definitely not “your regular fasting app”.

At first, you fill the DoFasting quiz and get a personalized fasting plan that will help reach your chosen weight loss goal. You also get an easy-to-do workout suggestions, healthy meal plan (you can even choose your preferred diet or note any allergies) and of course access all the typical intermittent fasting app features like – statistics, various tracking options and fasting schedules. And that all comes in a nice and easy to use design.

Overall, if your goal is to get fit and lose weight, this is the app that can get you there. You can download it here.

I'm looking for a do fasting app review. Can you share your review?
