Description by SAYAKA KAMIYA(from the App Store)
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.
