Timer
All audio is synthesized on the spot with WebAudio — nothing downloads or uploads. If you hear nothing, raise the phone volume and tap a button again.
Frequently asked questions
- Where do the sounds come from?
- They are generated live in your browser with WebAudio: there are no audio files, nothing downloads, and there are no loops to notice.
- Is it free?
- Yes, completely. No signup, no account, no time limit.
- How does the timer work?
- Pick 15, 30 or 60 minutes. When it runs out, the sound fades over ten seconds and switches itself off.
- Does it keep playing with the screen off?
- On most phones it keeps playing with the screen locked as long as the browser stays open. If it stops, allow background playback in your browser settings.
