# Calc vs Chain Calculator

The clearest difference is in-app purchases: Chain Calculator at none against Calc's 1. Chain Calculator also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.0). On price and device support there is nothing between them.

Both are free to download. Calc sells 1 one-off in-app purchase. Chain Calculator asks for nothing beyond the download.
