A sleep timer counts down to a time you choose, then alerts you so you know to put the phone down and settle in. To use it, open the sleep timer, set how many minutes you want, switch on the gentle fade if you like a soft cue, and press start. When it reaches zero it plays a quiet tone rather than a jarring alarm.
It runs in your browser, free, with no sign-up, and keeps working offline once loaded.
Set it and settle in
- Choose how long you want, with presets like 20 or 45 minutes or a custom number.
- Turn on Fade out gently if you want the alert to ease off rather than stop sharply.
- Press start. The display dims to keep glare down while the time runs.
- When it ends, a soft tone plays. Stop it and turn in.
The fade is the part that makes this a sleep timer rather than a plain countdown. Instead of one loud beep, the tone softens over a few seconds, so it nudges you toward sleep instead of pulling you out of it.
Good uses for a sleep timer
- Winding down before bed. Give yourself a fixed window to read or scroll, then let the timer signal lights out.
- Capping a nap. Set fifteen to twenty minutes so a short rest does not turn into a groggy hour.
- Quiet listening. Use it as a reminder to stop a podcast or playlist rather than drifting off with it running all night.
- Relaxation sessions. Time a breathing or stretching routine with a calm end cue.
What it can and cannot do
This is a timer with a soft alert, not a media controller. It cannot pause your music app or stop a video, because it only manages its own countdown. Treat the tone as your signal to stop whatever is playing, not as something that switches it off for you.
The count itself is reliable. Because it tracks a fixed end time rather than a tick that could pause, it stays accurate even if your screen dims. Keep the tab open so the tone can play, since some browsers quiet audio in fully hidden tabs.
When an alarm fits better
If you need to wake at a specific time of day rather than after a set number of minutes, the alarm clock is the better fit, with a louder tone and a snooze. For timing a single task during the day, a plain online timer keeps things simple.
