Zero - Fasting Tracker

By Courtney Circle

Open iTunes to buy and download apps.


Zero is a simple fasting tracker used for intermittent, 5:2, and circadian rhythm fasting. Choose your favorite fasting protocol and Zero will track your ongoing progress. Export your data to a spreadsheet for complete control.

Zero supports the following fasting types:

Circadian Rhythm Fasting: Based on the research from Dr. Panda (Salk Institute), participants are encourage to fast 13 hours per day, starting each fast at or before sunset. Zero uses your location to calculate the daily sunset time for the best possible accuracy.

Custom Intermittent Fasting: Setup a custom program to meet your fasting goals. You choose your fasting hours per day, and days per week.

5:2 Fasting: Based on the 5:2 fast diet, participants partake in five days of normal eating, followed by two reduced calorie fasting days.

What's New in Version 1.1

- Receive notifications when you meet your fast goal
- Change your fast start time before you stop fasting
- Other bug fixes

Important App

This app is very useful for keeping track of my fasting/eating-window goals; however, I would like to see a couple improvements made in future updates. First, I would like the option to edit previous fasting records for those times when I have forgotten, or it was otherwise inconvenient, to start or stop the app at the proper time. It would also be nice to be able to set a reminder in advance of the start of my normal fasting period in the evening. Other than that, I would like to thank the developer for a great app with a useful purpose in mind. This app has already helped me to achieve some personal BMI goals that I had been struggling with prior to finding this.

Awesome Tool for Fasting!

I love this app, and it I find that it really helps me stay committed to my fasting plan. When I finish my evening meal, I tap the button on the app to start tracking my time. Somehow that simple act makes it official and I am not tempted to cheat. I love how easy Zero is to use, too. I appreciate being able to edit my starting and stopping times because I sometimes forget to start and stop the app exactly when I start and end my fast. I also love being able to set a daily goal and seeing that I have reached it on the bar graph. Thanks for making it free!

Needs work

I realize this is a free app, probably written mainly for the developer's convenience, but I'd be willing to pay for it if there were some improvements made.

Free or not, the accounting of hours fasted needs to be fixed. For whatever reason, the app decided I fasted 28 hours on Monday, which is both impossible and confusing.

As for improvements, I'd love to see different options for time frames to be displayed (a month of results, etc.), the ability to edit more flexibly, alerts and timers — especially a timer that runs for a selectable amount of time after ending a fast and/or a warning alarm an hour (or whatever length of time I choose) before sunset.
