# そろばん問題集 vs そろばんノート

The clearest difference is ads: そろばんノート at none against そろばん問題集's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. そろばん問題集 sells 1 in-app purchase, starting at $1.99 per month and そろばんノート sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
