Don't get burned on bad centering. Scan your card against PSA, BGS, and CGC centering standards in seconds, even from an awkward angle. Free. No ads. No account needed. 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.

I’ve tried like three others before finding this one and this one is absolutely amazing I will definitely pay the $8 a month for this app. This needs to go straight to the top of the App Store when searching for card grading! **Developer response:** Thank you so much, GladiatorVet! Reviews like this genuinely make my day. Glad Rectifi stood out after you'd tried the others. More improvements are on the way, and I'm excited for you to see what's next. ### 5/5 — Broken after update + but quickly fixed *2026-05-27* 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. **Developer response:** 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! ### 5/5 — Underrated!!!! *2026-05-22* Developer has done black magic with this app. Nothing but great experiences and helps with pre grading immensely **Developer response:** Thank you for the review! I'm glad that Rectifi is helping you. If anything ever comes up or you'd like to see a feature added, support@getrectifi.com gets to me directly. ## Frequently asked questions about Rectifi ### What is Rectifi?
