# Calculator . vs 我的订单库

The clearest difference is iOS requirement: Calculator . at 16.0 against 我的订单库's 26. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Calculator . sells 4 in-app purchases, starting at $4.99 per 7 days and 我的订单库 sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
