# Asteroid Impact vs Star Odyssey

The clearest difference is ads: Star Odyssey at none against Asteroid Impact's shown. Star Odyssey also leads on update cadence (every 6 weeks vs every 15 months) and iOS requirement (12.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Asteroid Impact sells 1 one-off in-app purchase and Star Odyssey sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Asteroid Impact ships an update every 15 months, Star Odyssey every 6 weeks. The most recent releases landed on October 19, 2026 and October 5, 2026 respectively.
