Card centering apps and tools compared: public features
The best card centering tool depends on your workflow: browser or phone, photo handling, manual adjustments and whether both sides can be checked. This comparison records publicly declared features, not an accuracy ranking. Unspecified details remain unknown. Centering Lab is included under the same criteria, with its measurement limits and source-status distinctions made explicit.

How to read this comparison
“Not stated” means that the checked source does not establish the information, not that the feature is absent. “English page checked” describes the source we read, not the product’s complete language support. For mobile apps, a translated store page is not evidence that the app interface supports that language. Apps with the same title but different developers are separate products.
Photo selection and processing location are separate. An upload button can load a file locally; it does not establish server transfer. Only explicit first-party statements are recorded. CardGrade’s centering page was available in a recent first-party search copy but direct retrieval returned 503: that source is marked indexed, with no claim of a live test. PokeToGrade currently redirects to GradeValue; the current destination is cited.
Centering Lab under the same criteria
The website processes photos in the browser; the API/MCP receives images on the server. Front and back can be confirmed separately and combined. PSA, BGS, CGC and SGC are modeled with explicit source status; Beckett interpretations and approximate SGC rows are not official guarantees. No TAG or ACE numerical scale is modeled. The service is entirely free in six languages.
Automatic contours and printed lines can be wrong, especially with glare, dark or interrupted frames and transparent holders. Our reproducible accuracy test reports both improvements and failures. Centering Lab does not authenticate cards, inspect every condition defect or predict the final professional grade.
Choosing a workflow
Check whether you need browser-only photo processing, both sides in one result, manual corner/line controls, a downloadable result or a phone app. Confirm current access conditions at the linked source before paying. We did not upload test photos to competing services, buy subscriptions or independently benchmark their claimed precision. No sponsored ordering, ratings or affiliate links are used here.
