Frequently asked questions

Will it ring if my computer is asleep?
The alarm relies on the browser tab staying open and the device awake, so it is best for times when you are nearby with the page open. For waking from deep sleep overnight, a dedicated phone alarm is more dependable.
Why do I need to interact before setting it?
Browsers only allow sound to play after you have interacted with the page, which is what arming the alarm does. That single tap unlocks audio so the tone can ring when the time comes.
How long is a snooze?
Snooze re-arms the alarm for nine minutes from now, the familiar interval, then it rings again. You can stop it for good at any point.
Does it work offline?
Yes. Once the page has loaded it keeps running with no connection, because the whole tool runs in your browser. You can install it to your home screen and open it like an app.
Do I need an account, and is anything tracked?
No account and no sign-up. The tool runs on your own device, so there is nothing to log in to and your settings stay on your machine. No popups, no clutter.
