ZeroPop vs PSA App
PSA's official app: submission tracking, cert verification, pop reports, and the Set Registry.
The verdict
The PSA app is the official companion for cards you have already sent to PSA: track submissions, verify certs, check pop reports, and build a Set Registry, all free. ZeroPop is the step before that. It pre-grades a raw card with corners, edges, surface, and centering sub-grades and runs the slab-or-sell ROI math, so you know whether the card is worth a PSA submission at all.

ZeroPop vs PSA App: FAQ
Is ZeroPop a replacement for the PSA app?+
No, they do different jobs. The PSA app manages cards after you submit: tracking, cert verification, pop reports, and the Set Registry. ZeroPop works before you submit, pre-grading raw cards and running the ROI math on whether grading is worth it. Many collectors use both.
Does the PSA app pre-grade raw cards?+
Pre-grading raw cards with sub-grades is not what the PSA app is built for; its scanner identifies cards and its core tools cover submissions, certs, pop reports, and the registry. ZeroPop is built around the pre-grade: sub-grades, centering ratios, and a slab-or-sell decision.
Will a ZeroPop estimate match my final PSA grade?+
Not guaranteed. ZeroPop's grades are AI estimates meant to guide the submit-or-sell decision, and only PSA assigns an official PSA grade. The sub-grade breakdown shows you the evidence behind the estimate so you can judge the call yourself.
Grade, predict, and decide in one scan.
ZeroPop predicts PSA, BGS, and CGC grades with full sub-grades and runs the slab-or-sell ROI math on every card. Free to start.
