# Treequation vs Four 4s

The clearest difference is in-app purchases: Four 4s at none against Treequation's 1. Treequation's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price and device support there is nothing between them.

Both are free to download. Treequation sells 1 one-off in-app purchase. Four 4s asks for nothing beyond the download.
