Shared universes
Create a universe and invite friends. Every planet any of you finishes lands in the same sky, and when friends join your session, everyone’s planet grows side by side on one screen.
✨ Cosmie · Focus timer for iOS & Android
Grow a universe,
Grow a universe,
one focus session at a time.
Every minute you stay focused, a planet takes shape. Finish the session and it’s yours forever — drift away early and it cracks. Cosmie makes deep work something you can actually see.

How it works
Four stages between you and a finished planet
Pick a planet, set a timer, and put the phone down. Each stretch of focus pushes your planet one stage further — from bare rock to a living world.
-
01
Choose a planet
Browse your collection, pick the world you want to grow, and start a session of 20 to 120 minutes.
-
02
Focus, don’t flinch
The timer runs on the server, not on your goodwill. Leave the session early and the planet is added to your universe as a broken one.
-
03
Watch it come alive
Life spreads across the surface stage by stage. Come back tomorrow and keep the streak — and the momentum — alive.
-
04
Claim it forever
The finished planet lands in your universe, earns you coins, and stays there as proof of the hours you actually put in.
The collection
All 46 planets, every one of them yours to grow
Tap any planet to watch it grow through all four stages — exactly the way it does while you’re focusing. Some are free, some cost coins, some come with Premium — and a few are earned through achievements or gift codes.

Features
Built for focus that lasts longer than a week
Streaks that mean something
A 30-day heatmap colours in as you go, so one skipped day is visible before it turns into three.
Pomodoro cycles
Run focus and break blocks back to back. The cycle is tracked server-side, so closing the app or switching devices doesn’t reset your progress.
Coins & new worlds
Completed sessions pay out coins. Spend them on new planets — the collection grows because your focus did.
Your stats, honestly
Total focus time, sessions, favourite planet, longest streak, and how your universes compare. Cancelled sessions never count toward the numbers.
Friends & leaderboards
See who’s focusing right now and climb the daily, weekly and monthly global leaderboard — the top three wear a crown. Filter to friends, or hide yourself.
Focus Shield
Pick the apps that pull you away. While a session runs they stay locked behind a shield — and on a break the shield lifts by itself.
Achievements
Hit focus milestones to unlock achievements — some planets can only be earned this way.
Widgets & Live Activities iPhone
Your daily goal on the home and lock screen, and the session timer live in the Dynamic Island — breaks included.
Quitting has a cost
Cancel a running session and the planet still joins your universe — cracked, grey, and impossible to miss. Nothing is deleted and nothing is punished twice; you just get an honest record of the sessions you walked away from.

Your first planet is one session away
Twenty minutes of real attention. That’s the whole entry fee.
