# Calculator vs Memory＿Tool

The clearest difference is in-app purchases: Memory＿Tool at none against Calculator's 1. Memory＿Tool also leads on iOS requirement (13.0 vs 15.0). Calculator's advantage is device support. On price there is nothing between them.

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