The method
A short, auditable path from image to value.
The product keeps identification, evidence, and valuation separate so uncertainty never gets hidden behind a polished number.
- 01
Add the card
Upload up to eight images and record the exact printed identity, including rarity, finish, edition, and variation. Google can suggest visible label text from a compatible image, but you confirm every field.
- 02
Resolve the slab
For graded cards, grader plus normalized certification number is the duplicate key. Two legitimate certifications remain two inventory records.
- 03
Attach evidence
Sold price, shipping, source, sale date, verification state, and exact-match state remain visible and reviewable.
- 04
Calculate without guessing
Final Value is the highest verified exact sold total. Quick sale is 80% and replacement is 110%—only when Final Value exists.
Your storage boundary
Card records live in the app's cloud database and images live in private cloud storage, both readable only by your signed-in account. Google Drive is optional: it is a one-time import source for an older Drive inventory, and nothing in Drive is ever changed or deleted by the app.
