A beep plays when time is up (browsers require one interaction — like pressing Start — before audio is allowed). Keep the tab open; background tabs can be throttled. For reminders that survive closing the tab, use your device's alarm instead.

Private by design

This tool runs 100% inside your own browser using local JavaScript — your input never touches a server. That makes it instant, offline-capable in many cases, and private even for sensitive data.
