ReceptionRating · Positive reviews · Number of ratings

ExpiWell holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: ExpiWell has 1.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 39% of ExpiWell's written reviews are positive against 100% of UC ClassFinder's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
