LeanFast-Fasting & Weight Loss

One tap starts your fast — then it counts down on your Lock Screen and Dynamic Island as each metabolic stage unlocks. No guilt trips, no 20-question sign-ups.

LeanFast makes intermittent fasting simple, honest, and sustainable. Start a fast in seconds, watch your body move through each metabolic stage, and see real progress — without guilt trips, dark patterns, or 20-question sign-ups.
