Zero - Fasting Tracker

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.
