Airplane Chime Timer

Airplane Chime Timer is a free Chrome extension for hourly reminders, short breaks, and everyday routines. It plays airplane-style chimes without interrupting your screen with notifications. Choose how you want to be reminded: - Single timer: every 15 or 30 minutes, every hour, or a custom interval from 1 to 1,440 minutes. - Specific time: a one-time reminder or a daily repeating chime. - Dual timers: different sounds for short and long intervals, with the long chime taking priority when they coincide. Make the sound work for you: - Choose from the included chimes and test the sound before enabling the timer. - Adjust the volume, including mute. - Add your own MP3 or WAV file, up to 1 MB. - Check the next scheduled chime in the popup. Getting started: 1. Pin the extension and open it from the toolbar. 2. Choose a sound and interval, then test the volume. 3. Turn Timer Active on. The badge changes to ON. An English/Korean quick-start guide is available from the popup. For a 25-minute reminder, choose Custom interval and enter 25. This is a repeating reminder, not an automatic 25/5 work-and-break cycle. Chrome must stay running and your computer must stay awake. Chimes can play while another app is in front, but sleep, a closed browser, or system scheduling can delay or prevent playback. Timing is not guaranteed to the second. No account is required. Timer settings and uploaded sounds are stored locally in Chrome. The extension does not send your browsing history or timer activity to an analytics service.
