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 2023.

FAQ on intermittent fasting apps

Which is the best free intermittent fasting app?

It’s all a matter of what you’re looking for. From my experience, CLEAR app is definitely one of the top fasting apps overall. It has a top-notch design and all the necessary features you will need in an intermittent fasting app.

But feel free to scroll through the list and find what would work 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 fasting 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 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 easy-to-do workout suggestions, a 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?
