# 绳器 vs Offhand 随手写

The clearest difference is device support: Offhand 随手写 at 4 against 绳器's 2. 绳器's advantage is iOS requirement (11.0 vs 15.1). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 绳器 sells 1 in-app purchase, starting at $4.99 per month and Offhand 随手写 sells 1 in-app purchase, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.
