BUILT FOR TRADING CARDS WITH AUTOMATIC PERSPECTIVE CORRECTION
Other apps need a perfectly flat photo. Rectifi doesn't. Our app straightens your photo before measuring, so your ratios are accurate no matter how you hold your phone. Watch the perspective correction happen in real time.
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.
INTERACTIVE DEMO

Very useful app. Accuracy is not as good when the image is not 90 degrees, but as accurate as any other centering tool I’ve used.

Really sorry for the crashes - we caught a bug specific to iOS 26.4, and has been fixed in v1.3.2 or by updating to iOS v26.5. If anything's still off, email support@getrectifi.com and I'll dig in directly. Thanks for taking the time to flag it!
Underrated!!!!
