# 百思笔记 vs Coin Grader Pro

The clearest difference is ratings volume: Coin Grader Pro at 5 against 百思笔记's 1. On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. 百思笔记 sells 1 in-app purchase, starting at $0.99 per month and Coin Grader Pro sells 9 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for 百思笔记 against 5.0 for Coin Grader Pro. That said, the two scores are not equally well evidenced: Coin Grader Pro has 5 ratings behind it against 1, so its average is the more settled of the two.
