No account. No ads. Close the paywall and keep going.
FAST YOUR WAY
• Plans from 12:12, 14:10 and 16:8 to 18:6, 20:4, OMAD (23:1) and 5:2
• Longer fasts: 24, 36, 48 and 72 hours, 5 days and 7 days
• Or set your own length
• Started earlier? Backdate it. Ate early? Edit the end. Or pick an end time instead of a length.
SEE WHERE YOU ARE
• A ring that shows your fast and the stage you're in, from digesting and blood sugar settling to switching fuel, ketones rising and beyond
• Each stage has an evidence label (established, likely or emerging) and sources you can read
• Stage timings are typical averages from research, not measurements of your body
ON YOUR LOCK SCREEN AND HOME SCREEN
• Live Activity and Dynamic Island while you fast, and while your eating window is open
• Small and Medium Home Screen widgets, plus Lock Screen widgets
• Controls for Control Center, the Lock Screen and the Action button
• Siri and Shortcuts: "Start a fast in Sunwick", "How long have I fasted in Sunwick"
• Reminders for your usual start time, the last hour, your goal and each new stage. Act right from the notification: start now, +1 hour, finish or log your weight.
YOUR HISTORY, ALL OF IT
• Every fast on a calendar, with weekly charts and totals
• Streaks with freezes, so one off day doesn't wipe your progress
• Badges for milestones
• Weight and mood log
• Export everything as CSV, or delete it all, any time
HELP WHEN IT GETS HARD
• Craving SOS: a one-minute breathing break when hunger hits, with no guilt if you decide to eat
• Check-ins on long fasts, plus electrolyte and gentle refeed tips
• A Learn library of short reads on fasting, sleep, nutrition and more
OPTIONAL EATING WINDOW LOG
• Off until you turn it on
• Log meals by barcode, typing, a nutrition label photo or a meal photo estimate
• See how much protein is left for your window
• You check and edit every entry before it's saved
A BUDDY, NOT A NAG
• Name your flame buddy and pick an accessory
• It reacts to your fast and cheers when you reach your goal
• No "you failed" messages. Ever.

Everything above stays free. Plus adds:
• Your weight trend insight: how your 16h+ fasting days line up with your weight

SAFETY FIRST

Talk to a doctor before fasting longer than 24 hours, or if you have a medical condition or take medication. If you feel unwell, eat.
