# 可轉債 vs Mars

The clearest difference is device support: 可轉債 at 4 against Mars's 2. 可轉債 also leads on iOS requirement (9.0 vs 15.0). 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 Mars sells 1 in-app purchase, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.
