# Dayfast

> Dayfast is a mobile intermittent fasting tracker for 16:8, 18:6, and custom plans, with a live countdown, gentle reminders, and progress tracking.

Dayfast is a **HealthApplication** for iOS and Android — a fasting *timer and habit tracker*, not a calorie counter, meal plan service, medical device, or clinical program. Core tracking is offered as a **free service** (see Terms); treat store listings as source of truth for any commercial terms.
