# Kalkyl vs あとから直せる計算メモ

The clearest difference is in-app purchases: あとから直せる計算メモ at none against Kalkyl's 1. Kalkyl's advantage is device support (4 vs 1) and iOS requirement (15.6 vs 17.0). On price and ads there is nothing between them.

Both are free to download. Kalkyl sells 1 in-app purchase, starting at $4.99 per year. あとから直せる計算メモ asks for nothing beyond the download.
