AEON: Idle Universe
Relaxing cosmic clicker & sim
Free · In‑App Purchases
What will this universe look like? Every Big Bang can redraw the whole world - monochrome, pixel art, or green phosphor. Your progress now follows you to a new device.
AEON is a meditative, relaxing idle game about creating a universe from nothing.
Tap the screen to draw scattered interstellar dust together — particles pull on each other like real physics and slowly grow. Given enough mass they become a molecular cloud, then a blazing star, a star system with orbiting planets, a cluster of thousands of stars, a vast galaxy, and beyond — galaxy clusters, superclusters, and the observable universe itself.
Grow your cosmos far enough and Big Bang collapses it for a "cosmic constant." Strengthen the laws of physics — time dilation, fusion, gravity, dark matter — and open new laws and content on a discovery tree, so the next universe grows faster than the last.
Watch long enough and life sprouts on some world, and a civilization lights the windows of its cities. They send signals, form alliances or wage war, and wonder about the creator of their universe. You watch over it all — and, now and then, grant a blessing.

Ratings & Reviews
Three fixes.
- Fixed the "Codex Complete" achievement never unlocking even with every entry
discovered. It unlocks right away on update, with your existing records intact.
- Fixed unintended purchases when tapping near the top of the screen while the
shop was expanded and scrolled down.
- Fixed cloud saves not updating, which made the "Two universes diverged" prompt
come back on every launch.
All were found thanks to player reports. Thank you.
