# Goat Evolution vs Space Twins

The clearest difference is ads: Space Twins at none against Goat Evolution's shown. Space Twins also leads on review sentiment (100% vs 84%) and iOS requirement (12.0 vs 15.0). Goat Evolution's advantage is update cadence (every 5 weeks vs every 17 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Goat Evolution sells 10 one-off in-app purchases and Space Twins sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Goat Evolution ships an update every 5 weeks, Space Twins every 17 months. The most recent releases landed on October 20, 2026 and October 7, 2026 respectively.
