# 物理計算機 vs Formula Lab

The clearest difference is in-app purchases: 物理計算機 at none against Formula Lab's 1. Formula Lab's advantage is device support and iOS requirement (13.0 vs 15.5). On price there is nothing between them.

Both are free to download. Formula Lab sells 1 in-app purchase, starting at $1.99 per month. 物理計算機 asks for nothing beyond the download.
