# LetterSchool vs Math Slide

The clearest difference is rating: LetterSchool at 4.5 against Math Slide's 3.9. LetterSchool also leads on update cadence (every 2 months vs every 16 months) and ratings volume (17K vs 20). Math Slide's advantage is monetization model (free vs free with in-app purchases) and review sentiment (75% vs 55%). On price, ads, in-app purchases 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 and Math Slide sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

LetterSchool holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: LetterSchool has 17K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 55% of LetterSchool's written reviews are positive against 75% of Math Slide's, so the app with the better star average is not the one people write more warmly about.

LetterSchool ships an update every 2 months, Math Slide every 16 months. The most recent releases landed on November 1, 2026 and October 11, 2026 respectively.
