Remember when your morning personality ruined your last friendship. Mr Sleep saves you from your own bad timing.
Open the app, see the science-based wake-up times your brain actually likes, then set the alarm. That’s it. No yoga, no meditation, no creepy AI voice telling you to relax. Just numbers.
Why it works:
- Complete a sleep cycle: wake up like a human.
- Break a sleep cycle: wake up like a swamp monster.
Perfect sleep cycles do more than that overpriced mattress you brag about.
We’re not trying to replace your alarm app.
We’re just trying to make sure you don’t start your day with the energy of a potato.

What's New in Version 5.6
We finally asked another obvious question: "What if you want a bedtime reminder AND a wake-up alarm?"
Introducing Sleep Plans. Set your bedtime reminder and wake-up alarm at the same time. Revolutionary. Someone should've thought of this sooner. Oh wait.
Here's what's new:
- Sleep Plan mode: Tap once, get two notifications. One to tell you to go to bed, one to wake you up. Full service
- Prettier loading screen: The reminder now has the same fancy animation as the alarm setup. Because staring at a spinning ring for 1 second somehow feels more official
- Bug fixes: Fixed the bug where returning to the app would mysteriously switch modes and forget you had an alarm. We're as confused as you were
We did the math so you don't have to. You're welcome.
