Mr Sleep - Sleep Calculator

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.
