Centrd
Read full descriptionHide full description
FREE centering tool & grade calculator/ Centrd measures your card's centering to the exact percentage, tells you what each grading company would give it, and shows what it's worth at that grade — so you can decide before you spend $30 finding out. Works on any trading card. Pricing is currently Pokémon only — more games are coming. MEASURE ANY CARD Scan a card and Centrd finds the edges for you. Drag the four lines to the card edge and the print border, pinch to zoom up to 15× for the fine work, and read the exact left/right and top/bottom split. Front and back, because graders look at both. Works on any trading card — Pokémon, Magic, Yu-Gi-Oh, sports. EVERY GRADING STANDARD, SIDE BY SIDE PSA, BGS, CGC and TAG all publish different centering tolerances, and a card that's a 10 for one is a 9 for another. Centrd shows all four at once, with the rule behind each grade one tap away. Cards sitting right on a cutoff get flagged, because "too close to call" is more honest than a confident wrong answer. KNOW WHAT IT'S WORTH Centrd identifies your card automatically — name, set, number and artwork — and shows what it sells for. See prices at every grade, how they've moved over time, and how many copies already exist at each grade. Automatic identification and pricing currently cover Pokémon cards. Magic, Yu-Gi-Oh and sports cards can be measured and graded today, and pricing for them is the next thing being built. WORK IN BATCHES Scanning one card is fine. Preparing a submission is the real job. Group cards into batches, see the whole pile's value raw and at the grades your cards would actually earn, and work through them one at a time. WHAT'S FREE Scanning, centering, grade estimates, batches, and identifying your cards — all free, always. No ads. No watermarks. No grade hidden behind a paywall. WHAT PREMIUM ADDS Market prices at every grade, full price history, grader population reports, and batch value at the grades your cards would get. $3.99USD/month or $29.99USD/year. HONEST ABOUT WHAT IT IS Centrd measures centering. It does not assess corners, edges or surface, and it is not a grade predictor. The grades shown are what your card's centering alone would qualify for under each company's published standards. The rest is on your eyes, and the final call is always the grading company's. Not affiliated with Nintendo, The Pokémon Company, Wizards of the Coast, Konami, PSA, Beckett, CGC, TAG or SGC. Centrd Premium is an auto-renewing subscription — $3.99/month or $29.99/year. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your Apple Account settings.

Verdict
The clearest difference is ads: Centrd at none against UnSlabbed's shown. Centrd also leads on iOS requirement (16.0 vs 18.0). UnSlabbed's advantage is update cadence (every 5 days vs every 10 days). On price, in-app purchases and device support there is nothing between them.
