Verdict
The clearest difference is rating: BU Reserve at 4.2 against Piazza's 2.1. BU Reserve also leads on update cadence (weekly vs fortnightly). Piazza's advantage is ads (none vs shown) and ratings volume (277 vs 10). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
BU Reserve holds the better App Store score, 4.2 against 2.1. That said, the two scores are not equally well evidenced: Piazza has 277 ratings behind it against 10, 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 BU Reserve's, so the app with the better star average is not the one people write more warmly about.
Piazza ships an update fortnightly, BU Reserve weekly. The most recent releases landed on September 21, 2026 and September 10, 2026 respectively.
