About this app

Glass marbles with whole galaxies inside, right on your home screen.

Cosmarbox fills your phone with glowing 3D marbles. Flick one and it rolls across the floor, knocks into the others and bounces back from the edge of your screen. Tilt your phone and the picture moves with you, so the floor seems to sit deep behind the glass. Then look closer: inside every marble, a small world slowly turns.

✨ A WORLD IN EVERY MARBLE
• Glowing nebulae, spiral galaxies and drifting smoke, each in its own glass
• The heart of each marble and the stars around it turn slowly in opposite ways
• Twelve colours, from deep purple and cyan to gold and flame

👆 FLICK THEM AROUND
• Marbles roll, knock and bounce like the real thing
• A soft flick sends one drifting, a fast one scatters them all
• Leave them alone and they settle where they stopped

📱 TILT TO LOOK INSIDE
• Tilt your phone and the view shifts, like looking through a small window
• Glints of light slide over the glass as you move
• Hold it still and a gentle drift keeps the depth alive for a moment

🪵 FOUR FLOORS TO ROLL ON
• Soft velvet, rippled sand, rough stone and polished wood
• Each floor has its own feel: marbles roll on and on across the wood and stop fast in the sand

💎 FREE TO TRY
• Free: five marbles with nebulae inside, five colours, the velvet floor, every flick and every tilt
• Premium, a one-time purchase with no subscription: up to twelve marbles, galaxies and smoke, all twelve colours, the sand, stone and wood floors, six colours for the velvet and a slider for how deep it looks
• Works as a screen saver too
• Easy on your battery: it rests when the marbles lie still
• No ads, and no data collected
