# Pre vs 8th Grade Math Challenge

The clearest difference is rating: Pre at 4.7 against 8th Grade Math Challenge's 3.9. Pre also leads on ratings volume (357 vs 24). 8th Grade Math Challenge's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 2 months vs every 6 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Pre sells 1 in-app purchase, starting at $9.99 per month and 8th Grade Math Challenge sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Pre holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Pre has 357 ratings behind it against 24, so its average is the more settled of the two. Written reviews split almost evenly too, at 67% and 67% positive.

Pre ships an update every 6 months, 8th Grade Math Challenge every 2 months. The most recent releases landed on September 8, 2026 and July 16, 2026 respectively.
