The fasting timer that respects your time and your wallet. Ember is a beautifully crafted intermittent fasting timer that just works. No account required. No ads. No dark patterns.

Your progress is always a glance away. Start and stop fasts right from your home screen. BEAUTIFUL & FAST Launches in under a second. Your body runs multiple metabolic processes during a fast: fat burning, ketosis, autophagy. They overlap and build on each other gradually. Ember tracks your progress with smooth animations and warm, purposeful design. Choose from 10 curated color themes or set your own custom accent color. Pick from 8 app icon styles to match your aesthetic. METABOLIC INSIGHT (PRO) Fasting isn't a series of stages you enter and leave, it's overlapping biological processes that build on each other. Pro unlocks live metabolic process tracking: see fat burning, ketosis, and autophagy ramping simultaneously with intensity indicators. Tap the info icon during any fast to see exactly what's happening in your body. EVERYTHING YOU NEED, NOTHING YOU DON'T - All 5 popular protocols: 16:8, 18:6, 20:4, OMAD, or create your own - Streak tracking with milestone celebrations - History with weekly calendar view - Basic stats to track your progress - Smart notifications for fast completion, zone transitions, and daily reminders HONEST PRICING The full fasting timer is free.

About

FastLine

Read full description

FastLine is the intermittent fasting timer that does the one thing you actually open the app for — beautifully — and doesn't charge you $70 a year for a countdown. Start a fast and a clean count-up ring shows your elapsed time, your current stage, and how long until your goal. It lives where you'll actually see it: on your Lock Screen and in the Dynamic Island as a Live Activity, and on your Home Screen as a widget. No need to keep opening the app. HONEST PRICING The timer, fasting stages, history and stats are free, forever. Pro is an optional upgrade at a fair price — about twenty dollars a year, or a one-time lifetime unlock — not a $70 subscription hidden behind a countdown. WHAT YOU GET, FREE • Count-up fasting ring with time elapsed and time remaining • Popular protocols: 16:8, 18:6, 20:4 and OMAD • Live Activity on the Lock Screen + Dynamic Island • Home Screen widget • Educational fasting stages as the hours pass • History, current streak, averages and a 14-day chart PRO (OPTIONAL) • Custom fasting goals — set your own hours • Mood & energy notes on every fast • Weight trend from Apple Health • Export your history to CSV ON YOUR WRIST Glance at your fast on Apple Watch and start or end it without reaching for your phone. PRIVATE BY DEFAULT No account. No backend. Your fasts stay on your device. FastLine reads your weight from Apple Health only if you turn it on, and never writes your data anywhere. A NOTE ON HEALTH FastLine is an educational tracking tool, not medical advice. Fasting isn't right for everyone — talk to a doctor before making changes, especially if you are pregnant, nursing, taking medication, or have a history of disordered eating.
