Fasting Timer — Aayushnitya

Intermittent fasting timer: toolbar countdown, metabolic stages, streaks & alerts. Private, free, no account.

Fasting Timer is a clean, private intermittent-fasting clock that lives in your browser toolbar. Pick a protocol — 16:8, 18:6, 20:4, OMAD, or your own custom hours — hit start, and the toolbar badge counts down to your eating window. Open the popup for a full progress ring and your current metabolic stage. WHAT YOU GET • Live toolbar badge counting down your fast — and your eating window. • Progress ring with your real-time metabolic stage: Fed → Catabolic → Fat burning → Ketosis → Autophagy. • Custom fasts — start an ad-hoc fast without saving a preset. • Forgot to start? Edit or backdate your start time in one tap. • End-of-fast and eating-window alerts, plus optional metabolic-stage notifications. • Streaks and a 14-day history so you can see your consistency at a glance. • Switch between time remaining and time elapsed with a tap. PRIVATE BY DESIGN • No account, no sign-up. • No analytics, no ads, no tracking. • No servers — everything stays on your device. • No access to the pages you visit (no host permissions).
