# Colost vs Alien Shooter

The clearest difference is ads: Alien Shooter at none against Colost's shown. Alien Shooter also leads on iOS requirement (13.0 vs 16.0). Colost's advantage is update cadence (every 2 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Colost sells 7 one-off in-app purchases and Alien Shooter sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Colost ships an update every 2 days, Alien Shooter every 2 months. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
