Built for trading cards, Rectifi detects cards automatically, even on busy backgrounds. HOW IT WORKS 1. Snap a photo or import from your library 2. Place your card's corners one at a time 3. Perspective correction kicks in automatically 4. Get centering ratios and grade qualifications for PSA, BGS, and CGC. Toggle between front and back with a tap. GUIDED MODE: PLACE CORNERS WITH CONFIDENCE Rectifi walks you through corner placement one corner at a time. The screen zooms into each corner so you can line it up precisely before confirming. An on-device detector places every corner for you first, so most of the time a small adjustment is all it takes. Prefer placing all four corners at once? Switch to Manual mode anytime in Settings.
