Top 5 Best fasting apps for Android and iOS

In many countries, people observe fast for the entire day or week. When they do so, the only thing that people eat is raw fruits or a meal cooked without oil or spices. According to Harvard University, fasting can reduce bad cholesterol in the body, and it can also help you control or reduce weight without exercising.

If you’re healthy and practice fasting, you should continue your routine. If you’re unhealthy, you can use the fasting apps I’ve shared below. The applications have features that will help you achieve your health goals via the simple and effective route of fasting.

Best fasting apps for Android, iPhone, and iPad



Fastic displays 11 basic questions one after another and prompts you to choose an answer. Some of the questions are as follows:

  • What do you want to achieve with fasting?
  • How can the app help you in accomplishing your goal?

Fastic will build a plan once you answer each question. The program is based on your answers. Once your plan is ready, the app will open its main interface, where you’ll find options to:

  • Start the Fastic program.
  • Invite your friend to use the application and see his fasting plan.
  • Set water drinking reminders, etc.

The plans in Fastic include challenges. To participate in the challenge, you must buy the “Plus” plan of Fastic. The Fastic application ships with a timer utility. It allows you to set the duration for which you’d not eat food. Once you set the duration and tap the “Start” button, the timer will stop after N hours. For example, if you set the duration to 9 hours, the timer will stop after 9 hours. You must not eat food for 9 hours. The only thing you can intake is tea/coffee without milk/sugar and water. Fastic can import the step counter data from popular health apps such as Samsung Health, Google Fit, Fitbit, Garmin, and Polar. It enables you to track weight, fasting hours, and water you’ve drunk.

It displays an option to upgrade to the “Premium” version in the settings interface.

On its main interface, FA shows a list of programs. The programs display the fasting time in hours. Once you select a program/plan, FA will show a “Start Fasting” button and some valuable tips. This Fasting app for Android, iPhone, and iPad will start its timer if you tap this button. FA lets you track water intake, and it generates various types of graphs from the fasting data it has collected. FA divides the fasting hours into various levels.
