Another great check

I use HoloDex for some AI grading before deciding what to send off for grading. This app has made my mind up when HoloDex tells me it’s a 9 it’s actually a 10 for Ace as using the app shows me it’s well within the boundaries. It actually upgrades my centering scores for PSA as well. I scan my cards so this is super accurate. Impressed.

Not accurate

This app is not accurate at all. Every card scans as perfect 50/50 centering. I scanned off center cards and it registered as 50/50. Not a useful app.
OTOh so true

Littered with ads, do not download

This app was great when I first downloaded it. Now after measuring one card I can’t even upload another there are so many ads. Find another app.
