## What is Mr Sleep?

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.


## Version history (last 4 releases)

### 5.6 — 2026-01-22

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.

### 5.3 — 2025-11-19

What's New in Version 5.3

We finally asked the obvious question: "What if I already know when I need to wake up?"

Introducing Wake Up At mode. Instead of telling you when to wake up, we
now tell you when to go to bed. Same math, different direction. We're
innovators.

Here's what's new:
- Mode toggle: Toggle between "Sleep Now" and "Wake Up At" with a golden sliding pill that feels unnecessarily satisfying to tap

- Bedtime calculator: Pick your wake-up time, we'll tell you when to put down your phone and stare at the ceiling

- Remembers your choice: Switch to Wake Up At once and it stays there.

  We did the math so you don't have to. You're welcome.

### 5.1 — 2025-10-07

What's New in Version 5.1

We made setting an alarm more entertaining than it needs to be.

Your alarm bell now does a little dance when you set it up. Does it help you sleep better? No. Does it make you feel like
you accomplished something? Absolutely.

Here's what we polished:
- Fancy animations: The alarm bell swings, dings, and bounces like it's auditioning for a Pixar movie
- Sparkles: Because nothing says "optimal sleep cycles" like unnecessary sparkles
- Haptic feedback: Your phone vibrates to remind you that you're using technology
- Smooth loading states: No more UI glitches that make you question if the alarm actually set

Also, the app now knows what time of day it is and reorders wake-up times accordingly. We're basically geniuses.

Still won't help with your morning personality, but at least you'll wake up at the right point in your sleep cycle instead of mid-dream about that embarrassing thing you said in 2014.
