# Binairo vs Shikaku

The clearest difference is in-app purchases: Shikaku at none against Binairo's 1. Shikaku also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.6). On price and device support there is nothing between them.

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