# Piazza vs CourseMIRROR

The clearest difference is rating: CourseMIRROR at 3.0 against Piazza's 2.1. Piazza's advantage is ratings volume (279 vs 2) and review sentiment (14% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CourseMIRROR holds the better App Store score, 3.0 against 2.1. That said, the two scores are not equally well evidenced: Piazza has 279 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 14% of Piazza's written reviews are positive against 0% of CourseMIRROR's, so the app with the better star average is not the one people write more warmly about.

Piazza ships an update every 11 days, CourseMIRROR monthly. The most recent releases landed on October 14, 2026 and October 3, 2026 respectively.
