Verdict
The clearest difference is review sentiment: TrayMinder at 64% against Sphinx Orthodontics Online's 0%. TrayMinder also leads on update cadence (daily vs fortnightly) and ratings volume (5.3K vs 1). Sphinx Orthodontics Online's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. TrayMinder sells 5 in-app purchases, starting at $4.99 per month. Sphinx Orthodontics Online asks for nothing beyond the download.
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.
TrayMinder ships an update daily, Sphinx Orthodontics Online fortnightly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
