# PCGS Set Registry vs StackerTools App

The clearest difference is rating: PCGS Set Registry at 4.8 against StackerTools App's 4.3. PCGS Set Registry also leads on ratings volume (2K 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 80%). 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.

PCGS Set Registry holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: PCGS Set Registry has 2K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 80% of PCGS 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.

PCGS Set Registry ships an update every 3 weeks, StackerTools App every 2 weeks. The most recent releases landed on September 24, 2026 and September 8, 2026 respectively.
