# LetterSchool vs MathMod

The clearest difference is rating: MathMod at 5.0 against LetterSchool's 4.5. MathMod also leads on in-app purchases (none vs 14) and review sentiment (67% vs 54%). LetterSchool's advantage is ratings volume (17K vs 1). On price, ads and device support there is nothing between them.

Both are free to download. LetterSchool sells 14 in-app purchases, starting at $4.99 per month. MathMod asks for nothing beyond the download.

MathMod holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: LetterSchool has 17K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 54% of LetterSchool's written reviews are positive against 67% of MathMod's.
