# DoBuff vs 通信考研

The clearest difference is iOS requirement: 通信考研 at 12.0 against DoBuff's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DoBuff sells 3 in-app purchases, starting at $0.99 per month and 通信考研 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
