Verdict
The clearest difference is rating: PSA Set Registry at 4.8 against StackerTools App's 4.3. PSA Set Registry also leads on ratings volume (4.5K vs 19) and iOS requirement (11.0 vs 14.0). StackerTools App's advantage is monetization model (free vs free with in-app purchases) and review sentiment (94% vs 75%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
PSA Set Registry holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: PSA Set Registry has 4.5K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 75% of PSA Set Registry's written reviews are positive against 94% of StackerTools App's, so the app with the better star average is not the one people write more warmly about.
PSA Set Registry ships an update monthly, StackerTools App every 2 weeks. The most recent releases landed on October 9, 2026 and October 5, 2026 respectively.
