ONE - Your Complete Intermittent Fasting Tracker & AI Protein Calculator
Fasting made simple. Start a fast in one tap, watch your body move through
each stage, and build the streak that actually changes things.
ONE is an intermittent fasting timer and tracker built for people who want
the habit, not the homework — a simple fasting app that helps you lose weight. No account. No clutter. Just the timer, the stages, and your
progress.
Whether you're starting fasting or already experienced, ONE keeps you
consistent — ideal if you're looking for a bodyfast-style fasting
experience without the clutter.
