Sleep timer for Mac
A sleep timer for your Mac.
For years macOS could put itself to sleep on a schedule, through Energy Saver. Apple removed that from System Settings in macOS Ventura, and there was never a one-off "sleep in 45 minutes" timer like the iPhone's. Sleepr brings sleep timing back: a small menu bar countdown that puts your Mac to sleep after a set number of minutes, or at an exact time, so you can drift off to a podcast or a film without leaving it running all night.
What a Mac sleep timer does
A sleep timer counts down in the background and, when it reaches zero, triggers a normal system sleep: the same thing that happens when you choose Sleep from the Apple menu. Your music or video stops, the display turns off, and your battery stops draining. Nothing is force-quit, and unsaved work is left exactly as it was.
Didn't macOS do this before?
It did. The old Energy Saver let you schedule sleep and wake, but Apple dropped that from System Settings in macOS Ventura. Even then it was a single fixed schedule, with no quick "sleep in 45 minutes tonight," no one-off countdown from the menu bar, and no warning before the screen goes dark. Sleepr brings it back and adds all of that.
How Sleepr's timer works
- One-tap presets. Four durations a click away (15, 30, 60, 120 by default), each editable from 1 to 480 minutes.
- An exact bedtime. Pick a clock time like 11:30 PM and Sleepr does the math, including timers that cross midnight.
- Recurring schedules. Set a bedtime once, such as every weeknight at 11, and the matching timer starts on its own.
- A heads-up alert. A floating warning appears a few minutes before sleep, even over fullscreen video, so you can extend or cancel.
- Menu bar progress. Watch the countdown at a glance as a depleting ring, a waning moon, or a shrinking pie.
- Shortcuts and Siri. Four App Intents let you start, schedule, check, or stop the timer by voice or automation.
- Survives reboots. A running timer picks up where it left off after a restart.
