ReceptionRating · Positive reviews · Number of ratings

Sphinx Orthodontics Online holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: TrayMinder has 5.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 64% of TrayMinder's written reviews are positive against 0% of Sphinx Orthodontics Online's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TrayMinder ships an update daily, Sphinx Orthodontics Online fortnightly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
