Midpoint is a trading card centering and pre-grading tool that helps collectors evaluate cards before submitting them to professional grading services. Upload a card photo or use a phone camera to measure left-to-right and top-to-bottom centering in millimeters, then review estimated grades for PSA, BGS, CGC, and TAG.

The app uses image analysis to detect card edges and print frames, with manual controls for fine-tuning measurements. Each analysis can include centering ratios, predicted grades, and surface checks for edges, corners, print quality, and holo patterns. Midpoint also supports bulk uploads for reviewing multiple cards, sorting results by centering, saving selected cards to a collection, and generating cleaned, straightened images for listings or sharing. It is available on web, iPhone, and Android, with card data synchronized across devices.
