# Calculus vs 初中数学思维

The clearest difference is price: Calculus at Free against 初中数学思维's $1.99. Calculus also leads on device support (3 vs 1) and iOS requirement (17.6 vs 26.1). 初中数学思维's advantage is in-app purchases (none vs 1). On ads there is nothing between them.

Calculus is free to download; 初中数学思维 costs $1.99 up front. Calculus sells 1 one-off in-app purchase. 初中数学思维 asks for nothing beyond the download.
