# Altitude Checker vs モジチェン

The clearest difference is in-app purchases: モジチェン at none against Altitude Checker's 1. モジチェン also leads on ads (none vs shown). Altitude Checker's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price there is nothing between them.

Both are free to download. Altitude Checker sells 1 one-off in-app purchase. モジチェン asks for nothing beyond the download.
