Ember - Fasting Tracker

Start free for 7 days. Track your fast through 5 metabolic zones, keep your streak alive with Streak Shield, and see honest science — no pseudoscience, no guilt.

Ember is the fasting tracker that tells you the truth. No pseudoscience. No guilt. Just your journey, visualised. Try Premium free for 7 days.

Track your intermittent fasting with beautiful, real-time zone visualisation. Ember guides you through five science-backed metabolic zones — from post-meal processing to deep fasting — with honest language about what's happening in your body.

REAL-TIME ZONE TRACKING Watch your progress through five metabolic zones with a stunning journey-map visualisation. Each zone is backed by published research, and we use honest language like "likely" and "research suggests" — because your body is unique.

MULTIPLE FASTING PROTOCOLS Choose from popular intermittent fasting schedules:

• 16:8 — The most popular daily fast
• 18:6 — A step up for experienced fasters
• 20:4 — The warrior diet approach
• OMAD — One meal a day (Premium)
• 36-hour — Extended fasting (Premium)
• Custom protocols (Premium)

BEAUTIFUL TIMER A warm, minimal timer with a circular progress ring that changes colour as you move through zones. Long-press to end a fast — no accidental taps.

FASTING HISTORY View your fasting calendar as a heat map, inspired by contribution graphs. See your patterns at a glance with four intensity levels based on fast duration.

STREAKS & STREAK SHIELD Build a daily fasting streak and watch your flame grow. Miss a day? Streak Shield (Premium) lets you repair a broken streak so one slip doesn't erase weeks of progress. View your total fasts, total hours, average duration, and longest fast.

WEIGHT TRACKING Log your weight and see trends over time with a clean area chart. Your weight data stays private and secure.

POST-FAST REFLECTIONS After each fast, capture how you felt, what broke your fast, and any notes. Build a personal journal of your fasting journey.

OFFLINE-FIRST Ember works without an internet connection. Your data syncs to the cloud when you're back online.
