About

Ember

Most fasting apps just count the hours. Ember shows you what those hours are actually doing. Start a fast with one tap and a warm, living timer fills toward your goal. As time passes, Ember tells you exactly where your body is — easing out of digestion, tipping into fat-burning, crossing into ketosis, and reaching autophagy, the deep cellular clean-up so many people fast for. A fast stops being a countdown and becomes a journey you can watch. Choose the rhythm that fits you — 14:10 to ease in, the classic 16:8, 18:6, or push into 20:4, OMAD and 36-hour fasts. Ember keeps your streak gently (miss a day and it simply starts again), charts your weight over time, and lets you note how each fast felt. A home-screen widget keeps your time remaining a glance away, and everything syncs privately through your own iCloud. Ember is free to use, with an optional Ember Pro subscription that unlocks every fasting stage, unlimited history, full weight and insight charts, the advanced schedules and the widget. Pro starts with a 7-day free trial. Begin your first fast today — and finally see what's happening inside. Auto-renews unless cancelled at least 24 hours before the period ends; manage in your App Store account settings.
