# 牙科圈 vs 经链

The clearest difference is device support: 牙科圈 at 2 against 经链's —. On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. 牙科圈 sells 7 one-off in-app purchases and 经链 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
