# Calc vs CalcMemo

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

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