An Insight on How to Develop a Best Intermittent Fasting App

The tough times that the world has seen in 2020 due to the pandemic act as an eye-opener for many. A year that helped us realize how important our health and fitness can prove to be. Millennials nowadays like investing in playing sports, gym, yoga, and meditation practices, and much more. This wave of fitness has given a platform to the health and fitness industry and started a healthy revenue stream.

The concept of ‘Intermittent Fasting’ has taken the spotlight since apps like ‘Zero’ received success. Intermittent fasting or IF is a process of improving one’s physical and mental health by introducing patterns in the way one eats. It focuses more on ‘when to eat’ rather than on ‘what to eat’.

What is Intermittent Fasting App?

Fasting has been a part of human evolution. In the hunter-gatherer phase, we didn’t have the luxuries of a refrigerator, ready-to-eat foods or supermarkets. The availability of year-round food was also scarce. This tuned our bodies to stay hungry for longer hours. Fasting also holds religious importance in Hinduism, Christianity, Islam, Judaism, and Buddhism.

Intermittent fasting can be carried out by trying several combinations of eating and fasting. For example, one can choose the conventional 16:8 schedule. Here the individual would have to practice a fast for 16 hours while s/he can eat their desired meals in the remaining 8 hour period. Different fasting regimes can be inculcated by people as their bodies start getting used to the fasting process.

Several IF apps have experienced unprecedented success in recent years. Let’s learn the statistics that would help paint a clearer picture.



Statistics provide us with numbers that portray the way customers respond to a particular service. Here are some intriguing stats for health and fitness apps.

  1. At the start of 2019, the number of health and fitness apps on Google Play had reached 37, 154.
  2. In 2018, the global health funding for digital platforms amounted to 14.6 billion USD.
