About this timer app

TightTimeLog is a free web app that runs in your browser: choose presets (30 seconds, 1 minute, 3 minutes) or set any duration with minutes and seconds. Completed sessions can be saved as a dated log with optional short memos in IndexedDB on your device—nothing is uploaded to our servers.

Use it offline after the first load as a simple PWA, export logs as JSON for backup, and switch between English and Japanese. Typical uses include speech drills, plank holds, cooking timers, Pomodoro-style focus blocks, and quick routines you want to remember.

This is a personal productivity aid, not medical, legal, or employment advice. For official records or compliance, use tools and processes approved for your situation.

Haptic feedback

Adds a short vibration when you tap Start, Pause, or Reset on supported devices.

Depending on your device, browser, and system settings (silent mode, battery saver, accessibility, or vibration off), feedback may not occur even when enabled.
