# 笔杆文库 vs 笔墨写作

The clearest difference is device support: 笔墨写作 at 3 against 笔杆文库's —. On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. 笔杆文库 sells 5 in-app purchases, starting at $4.99 per 7 days and 笔墨写作 sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
