KNOW YOUR PHASE.

The ring tracks your window; the label tracks your body. Fed, fat burning, autophagy — grounded in established fasting science, shown live on the timer.

NOTHING TO SELL.
NO ONE TO TELL.

Fasts, streaks, and meals are stored locally on your phone. No servers, no accounts, no analytics — we couldn't read your data if we wanted to.

FOOD PHOTOS: ANALYZED BY A SECURE API → DISCARDED IMMEDIATELY. NEVER STORED. NEVER USED FOR TRAINING.
