Make time up impossible to miss. Train Horn Timer plays a bold five-chime train horn when your countdown finishes, with a large STOP button to end the sound.
Set hours, minutes and seconds, or choose a quick preset from one minute to one hour. See the countdown at a glance, cancel it with one tap, or use Test the horn to hear a short preview.
The timer uses Android exact alarms so it can finish while the app is in the background. The horn plays through the alarm audio channel and vibrates until you stop it. The app attempts to raise alarm volume while the horn plays and restores the previous volume afterward. Your device settings and Do Not Disturb can affect what you hear.
Free, no ads, no account, and no Internet permission. Timer settings stay on your device.
Set a countdown and let a loud five-chime train horn announce time is up.
