Pick a protocol, start the timer, get pinged when your eating window opens. Private by design — no account, no cloud.
Open fasttimer — it’s freeruns in your browser · installs as an app · works offline
The big fasting apps charge a subscription for a timer, then upsell coaching and trade in your “insights”. fasttimer is the opposite: a clean timer you buy once, with your history stored on your device — and nowhere else.
Start a fast and forget it. When you hit your goal, you get one notification — on Android even with the app closed. No streak-shaming, no push spam. One ping, when it matters.
