# Isotropy vs Arrow Out 3D

The clearest difference is in-app purchases: Arrow Out 3D at none against Isotropy's 1. Isotropy's advantage is ads (none vs shown) and iOS requirement (6.0 vs 12.0). On price, review sentiment and device support there is nothing between them.

Both are free to download. Isotropy sells 1 one-off in-app purchase. Arrow Out 3D asks for nothing beyond the download.
