# Numerithm vs Dochi

The clearest difference is in-app purchases: Dochi at none against Numerithm's 1. Numerithm's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 15.0). On price and ads there is nothing between them.

Both are free to download. Numerithm sells 1 one-off in-app purchase. Dochi asks for nothing beyond the download.
