# 可轉債 vs 算利方程式

The clearest difference is device support: 可轉債 at 4 against 算利方程式's 2. 可轉債 also leads on iOS requirement (9.0 vs 13.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 可轉債 sells 1 in-app purchase, starting at $8.99 per month and 算利方程式 sells 1 in-app purchase, starting at $23.99 per month. Whichever you choose, the download price is not the number that matters.
