Sundial

One meal. One ring. No subscription.

Sundial is a local-first intermittent-fasting and OMAD tracker for iPhone. A golden sun crosses a dial as your fast deepens — that’s the whole interface. The timer, every protocol, zones, history, stats and export are free, forever. One optional $19.99 purchase unlocks cloud backup, Insights and the full Field Notes library — once, not yearly.

Frequently asked

I bought Lifetime on another device. How do I restore it?
Open Settings inside the app and tap “Restore purchases”. The unlock is tied to your App Store account, not the device.
How do I export my data?
Settings → Export. You’ll get a CSV or JSON file with your complete history — free, no account needed.
I forgot to stop the timer. Is my history ruined?
No. Open the fast in your journal and edit its start or end time. You can also log past fasts manually.
Where is my data stored?
On your device. Nothing leaves your phone unless you turn on the optional cloud backup. See the privacy policy.
