U keep grading my psa 10 8.5?lol
Response from developer
Thanks for the feedback, this is genuinely helpful. A couple things worth knowing: if you’re scanning cards inside their slabs, glare off the case can lower what the AI sees, so raw or well-lit, glare-free photos give the most accurate read. It’s also worth noting that ZeroPop grades every card fresh against consistent, current standards, so it can occasionally read a card differently than the grade on the label, especially on older slabs. We’d rather give you an honest, consistent assessment than an inflated one. That said, we recalibrate regularly and examples like yours help us improve, so please reach out through the app and we’ll take a look at your scans.
Scam app
Response from developer
Hi, sorry to hear ZeroPop missed the mark for you. It’s a real product built and maintained by an indie developer, with AI grading estimates, collection tracking, and live pricing, plus a free tier so you can try everything before paying. If something didn’t work as expected, reach out through the support link on our App Store page and we’ll make it right. Robert, ZeroPop
Great
Decent grader
Response from developer
Thanks for taking the time to write this up, and for grading against your own tools. Feedback this specific is rare and genuinely useful. You nailed the centering point. We measure centering instead of eyeballing it, exactly because most AI graders fall apart there, so hearing it line up with your centering tool means a lot. On corners, edges, and surface, your read matches what we see internally. Those three run a little optimistic against strict graders, and tightening them is what we are heads down on right now. We want accuracy, not friendly grades, so we are calibrating those three down to match. On Slab or Sell, you caught a real bug and we already fixed it. The newest version pulls real sold comps for graded cards, so a 1968 Brooks Robinson PSA 10 will show a true market value, not $56. Update and rescan it and you should see the difference. If anything still looks off, email me, I want to see it. Really appreciate you pushing us.
So Cool!
This is a must for any collector.
Great APP
Not accurate
Response from developer
Appreciate the feedback. ZeroPop’s pre-grade is an AI estimate from two photos. PSA grades in-hand with calibrated equipment, and even they grade the same card differently on resubs (which is why crack-and-resub is a whole market). We intentionally err conservative so people aren’t overpaying for submissions. Congrats on the 9s and 10s, that’s a great outcome for you. Feel free to send us a support email and we’ll look into your grade and why this happened.
