# MathPK vs CastReader

The clearest difference is ratings volume: CastReader at 42 against MathPK's 1. CastReader also leads on device support (3 vs 1). MathPK's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MathPK sells 3 in-app purchases, starting at $0.99 per month and CastReader sells 5 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

MathPK holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: CastReader has 42 ratings behind it against 1, so its average is the more settled of the two.
