Fasting with Zero
Intermittent fasting is an eating plan where you switch between eating and fasting on a regular schedule.

Intermittent fasting, currently one of the world’s most popular health trends, is not concerned with what you eat, but rather when you eat. There are a number of apps and services that can help keep track of your fasting. One of these apps is Zero.


Zero is available on the App Store and the Google Play Store. While it’s free to download and use, it also has a subscription plan that enhances the fasting experience.

Launching the app takes you through a 5-step onboarding process that introduces the app, guides you through choosing a fasting plan, setting the timer and creating an account to track your fasting.

Zero gives you 5 fasting reasons:

Fasting suggestions and summary.

Once you’re done with the previous step you’ll be provided with the fasting type that applies to you, as well as the option to create an account for tracking your fasting sessions. You can also log into your account if you’ve got one already.


Since intermittent fasting tracks when you have your meals, a reliable timer is integral to the whole process. Zero delivers one that does just that in the timer screen.

The total number of people fasting at the current time is displayed at the top, with your current fast displayed under it, which you can tap to change the type of fast you’re doing.

The large circular timer is displayed at the center of the screen, and it has two states:


This displays the time since the last fast, as well as the upcoming fast duration. You can also change the type of fast, set a fasting reminder as well as start a new fast.
