# 笛子指法 vs 电波浪

The clearest difference is in-app purchases: 笛子指法 at none against 电波浪's 1. 笛子指法 also leads on iOS requirement (13.0 vs 16.0). 电波浪's advantage is device support. On price there is nothing between them.

Both are free to download. 电波浪 sells 1 one-off in-app purchase. 笛子指法 asks for nothing beyond the download.
