# Goat Evolution vs 21 Trainer

The clearest difference is in-app purchases: 21 Trainer at none against Goat Evolution's 11. 21 Trainer also leads on ads (none vs shown). Goat Evolution's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price there is nothing between them.

Both are free to download. Goat Evolution sells 10 one-off in-app purchases. 21 Trainer asks for nothing beyond the download.
