# フラッシュ暗算ドリル vs そろばんノート

The clearest difference is in-app purchases: フラッシュ暗算ドリル at none against そろばんノート's 1. フラッシュ暗算ドリル also leads on iOS requirement (13.0 vs 17.0). そろばんノート's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. そろばんノート sells 1 one-off in-app purchase. フラッシュ暗算ドリル asks for nothing beyond the download.
