FastRing

iOS · Lock Screen & Dynamic Island

A fasting timer you glance at, not one you open.

Start the fast and it moves to the Lock Screen and Dynamic Island, where a ring fills as the hours pass. No feed, no coach, no streak guilt — just the time remaining and a clean log of what you’ve done.

Features

Everything on the glance screen.

Live Activities
The fast lives on the Lock Screen and in the Dynamic Island through fasts as long as 36 hours. End one without unlocking your phone.
Any protocol
16:8, 18:6, 20:4, OMAD (23:1), 36-hour, or any custom length — with backdating in two taps when you forgot to start it.
Streaks that stay honest
A GitHub-style history heatmap with current and longest streaks and your 7-day average. A record, not a scoreboard.
Stage notes, optional
Notes on commonly cited fasting milestones — blood sugar, glycogen, ketosis, the autophagy window — if you want them.
Recurring schedules
Set something like “Every Tuesday,” pre-armed with a reminder an hour before it starts.
No account
No analytics and no third-party anything. Your history syncs only through your own private iCloud.

On device

A timer has no business knowing your email.

FastRing has no sign-up, no server of mine and no analytics. Your fasting history lives on your device and syncs only through your own private iCloud. The timer itself works fully offline, permanently.

Pricing

Free, then one payment.

The full timer, every preset, and your last 7 days of history are free, always.

A one-time Lifetime Unlock adds unlimited history, recurring schedules, Home Screen and Lock Screen widgets, stage notifications, and CSV / JSON export. No subscription, and no trial that flips into a charge.
