# LetterSchool vs Endless Numbers

LetterSchool and Endless Numbers both sit at 4.5 stars, but that hides the real split: 78% of Endless Numbers's written reviews are positive against 54% of LetterSchool's. Endless Numbers also leads on iOS requirement (10.0 vs 15.0). LetterSchool's advantage is ratings volume (17K vs 1.5K). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. LetterSchool sells 14 in-app purchases, starting at $4.99 per month and Endless Numbers sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for LetterSchool against 4.4 for Endless Numbers. That said, the two scores are not equally well evidenced: LetterSchool has 17K ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews are what separate them: 54% of LetterSchool's written reviews are positive against 78% of Endless Numbers's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
