Pick a plan like 16:8 or OMAD, tap Start, and follow your fast through fat-burning and ketosis in real time. And it respects you: no account, no social feed, no notification spam. Just you, your fast, and a clean tracker that does its job. Open it only when you actually need it. WHAT YOU GET • One-tap fasting timer with progress ring, countdown, and Live Activity on the Lock Screen and Dynamic Island • Popular plans — 12:12, 14:10, 16:8, 18:6, 20:4, OMAD — plus fully custom schedules • Metabolic zones — see when you enter glycogen depletion, fat burning, and ketosis • AI Coach (premium) — ask anything about your fasting, get answers tuned to your goals • First-meal log — snap a photo to capture what breaks your fast • Weight and body measurement tracking with trend charts and personal records • Progress photos with optional Face ID lock (premium) • Hydration tracking during your eating window • Streaks, weekly consistency, and milestones • Apple Watch app and Siri shortcuts: "Start a fast in Omady", "Log a glass of water" • Widgets and Live Activity for instant progress at a glance HOW IT WORKS 1.
