## What is CatSleeper?

25 minutes of focus, 5 minutes of break. The longer you leave your phone alone while you work, the more light and time fill your cat's room.

CatSleeper pairs a focus timer with a collection of cozy cat worlds.

HOW IT WORKS
• Focus for 25 minutes, then take a 5-minute break. After 4 rounds, enjoy a longer 15-minute break
• Jot down what you're working on in one line, then just close your phone
• A quiet notification lets you know when a focus session ends
• Breaks start when you're ready — no notification rushes you into one

COLLECT CATS AND THEIR ROOMS
• The one world you choose during onboarding is free to keep
• The other five cats can be unlocked individually or all at once (in-app purchase)
• Each room's light shifts through morning, day, evening, and night
• The more you focus, the cozier each room becomes

A CAT ON YOUR HOME SCREEN
• Add a widget to keep your chosen cat right on your home screen

No ads. No streaks to protect, no fear of missing out. Just a quiet world that grows a little every time you close your phone to focus.
