Cosmica: Idle Universe

Build your observatory empire across the cosmos. Tap to discover Stardust, buy telescopes and probes that earn for you while you're away, and ascend through seven cosmic tiers as you uncover the universe one generator at a time.

Cosmica is a relaxed idle game with infinite progression. Start with a backyard telescope and grow to operate Dyson Swarm Lattices, Multiverse Receivers, and the Demiurge Engine itself. Every generator you buy earns Stardust automatically — even when the app is closed.

▸ TAP & IDLE
Tap the cosmic orb to discover Stardust manually, then buy generators that produce it for you 24/7. Offline earnings catch you up when you return.

▸ SEVEN COSMIC TIERS
Stargazer → Astronomer → Astrophysicist → Cosmologist → Galactic Cartographer → Architect of the Void → Demiurge. Each tier grants a permanent earnings multiplier that survives even Big Bang resets.

▸ BIG BANG PRESTIGE
Hit the lifetime threshold and trigger a Big Bang reset. Your generators reset to zero, but you earn Cosmic Shards — each granting +2% permanent earnings, compounding forever.

▸ THE COSMIC TREE (NEW in 1.2)
Spend Cosmic Shards on 10 permanent skills: Cosmic Focus, Harvest Moon, Deep Field, Wormhole Resonance, Multiverse Weave, Big Bang Yield, Tap Mastery, Nightwatch, Vanguard, and Boost Extension. Every Shard you spend reduces your passive multiplier — a real invest-or-hoard tension every prestige.

▸ DAILY REWARDS (NEW in 1.2)
A 7-day cycle of escalating rewards — Stardust, Cosmic Shards, and 2× boost windows. Come back every day, keep the streak alive.

▸ COSMIC EVENTS (NEW in 1.2)
Timed buff windows kick in as you play: Supernova (2× production), Meteor Shower (3× taps), Wormhole (2× shard grants), Gravity Well (1.5× everything), and Big Bang Echo (+50% next prestige yield).

▸ GENERATOR SPECIALIZATIONS (NEW in 1.2)
Once you own 25 of a generator, commit it to Overcharged (+75%), Attuned (+50%), or Steady (+30%). Choice locks in for the run and resets on Big Bang — fresh strategy every prestige.

▸ 12 GENERATORS, 36 UPGRADES
From Backyard Telescope through Orbital Imager, Wormhole Sensor, Galactic Survey Net, all the way to the Demiurge Engine.

▸ FREE TO PLAY
Free download with rewarded ads. Optional Remove Ads ($2.99) or a range of boost & shard IAPs — your choice.

▸ ICLOUD SYNC + GAME CENTER
Your save syncs automatically across all your Apple devices via iCloud. Game Center leaderboards for lifetime Stardust, total prestiges, and highest tier achieved.

▸ NO ACCOUNT, NO ANALYTICS, NO TRACKING BY THE DEVELOPER
Single-player idle. The developer does not run a server, does not collect analytics, and never sees your data. Your progress is yours, on your device and in your private iCloud account.

Built solo by an indie developer. If Cosmica earns a spot in your day, Settings → Leave a tip helps keep the updates coming.

Have fun, observer.
