Intermittent Fasting Timer — No Signup Required

Most dedicated fasting apps require creating an account before you can start your first timer. This tool is different: open the page, select your protocol (16:8, 18:6, 20:4, or OMAD), enter your last meal time, and your countdown starts immediately. No email, no password, no subscription tier. Your session history is stored in IndexedDB — a private database inside your own browser — and you can export it as a CSV at any time. The tool works offline once the page has loaded, making it a practical daily companion without the overhead of a native app. Add it to your home screen on iOS (Share → Add to Home Screen) or Android (browser menu → Add to Home Screen) for one-tap access without installing anything from an app store.
