# 小地球仪 vs Chat Know

The clearest difference is device support: 小地球仪 at 2 against Chat Know's —. Chat Know's advantage is iOS requirement (12 vs 15.0). On price and in-app purchases there is nothing between them.

Both are free to download. 小地球仪 sells 6 one-off in-app purchases and Chat Know sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
