to know what their cards are actually worth before sending them to any grading company!

Most grading apps give you a single number from a single photo and
ask you to trust it. PreGrade Ultra shows you the measurements behind the
prediction, every centering ratio, every print tilt detection, every
sample point along every border. If the app says your card grades a 9 at
a specific company, you can see exactly why.

WHAT IT DOES

- Centering analysis using four published methodologies — Strictest Point,
Sustained Region, Center Sample, and Edge-Wide Average — measured at 20
points along each border, front and back

- Print tilt detection that catches art-layer rotation invisible to the
naked eye, with severity grading and per-axis breakdown

- Multi-grader predictions for PSA, BGS, CGC, SGC, TAG, ACE, and AGS, each
using its own threshold standards

- Cross-Grade Opportunity insights showing which grading company is most
likely to give you the highest grade on this specific card

- Border Sample Map that overlays every measurement directly on your card
image so you can see exactly where the off-centering is

- Edge curvature correction for warped cards using homography expansion

- Background trim detection that automatically corrects for capture
contamination so your measurements aren't biased

- Inspection filters across six processing levels for surface inspection

- Session history with full measurement archive and ROI calculator

WHY IT'S DIFFERENT

PreGrade Ultra was built around a simple idea: you should be able to
verify every number the app gives you. No black-box AI scores. No "trust
us" moments. The math is published, the measurements are visible, and the
methodology pages explain how each grading company actually evaluates
cards.

PreGrade Ultra uses geometric analysis grounded in your card's actual measured
dimensions, not pattern-matching against a model that shifts with
lighting.

WHO IT'S FOR

Serious Pokémon collectors who are evaluating cards for grading
submission. Resellers who need defensible measurements when listing.
Anyone tired of '8.5' grade with no explanation.

If you have a $300 card and you're trying to decide whether to send it
to a specific grading company, this is the app you want.

TRANSPARENCY NOTE

PreGrade Ultra estimates grades based on centering, tilt, and visible
surface inspection. Final grades from PSA, BGS, CGC, SGC, TAG, ACE, and
AGS depend on factors only the graders themselves can evaluate, including
hands-on surface examination and corner integrity assessment. Use this
app to inform your submission decisions, not to predict graded outcomes
with certainty.
