# Crash Course vs Quizzelo

The clearest difference is update cadence: Quizzelo at every 5 days against Crash Course's every 4 months. Quizzelo also leads on review sentiment (100% vs 76%). Crash Course's advantage is ratings volume (1.6K vs 4) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Crash Course sells 13 one-off in-app purchases and Quizzelo sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Quizzelo holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Crash Course has 1.6K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 76% of Crash Course's written reviews are positive against 100% of Quizzelo's.

Crash Course ships an update every 4 months, Quizzelo every 5 days. The most recent releases landed on October 20, 2026 and October 19, 2026 respectively.
