Sunwick is a fasting timer for 16:8, OMAD and 72-hour fasts. The timer, every plan, your Home Screen and Lock Screen widgets and your full history are free, forever. Your little flame buddy glows brighter the longer you fast.
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
