What Zero - Intermittent Fasting Is Used For

Zero - Intermittent Fasting appears to be a phone app for tracking intermittent fasting routines and related health goals. Based on the metadata, it is used to set fasting windows, start a timer, and follow progress over time, which makes it relevant for people who want a structured way to manage fasting without manually counting calories. The Health & Fitness category and the title suggest its main focus is weight management and routine tracking rather than general nutrition logging.

The app also appears to support progress review through statistics and journaling, and it may connect with Google Fit to show related health markers such as weight and sleep. That suggests it can be used as a personal wellness tracker where users monitor how fasting fits into broader habits. Several permissions, such as activity recognition, fitness data access, notifications, alarms, and network access, fit a timer-and-tracking app that sends reminders, syncs data, and updates progress in the background.
