Straighten leaning buildings in one tap, keep your HDR, and now keep your documents too. Shoot a building from street level and a wide-angle lens makes the walls lean inward. AutoAlign works out the exact angle the photo was taken at and reverses it, so verticals stand straight without the stretched look other tools leave behind. No tripod, no tilt-shift lens. NEW IN 4.0 • Documents: scan receipts, letters, cards and slides, one shot per page. Pages are cropped, straightened and filed by type. • Ask Documents (experimental): ask about your documents with the on-device model of Apple Intelligence. • A new editor in the style of Photos, and several photos at once. STRAIGHTEN • A perspective engine built on real camera geometry, the mathematics professional desktop tools use. Straight lines come back straight and proportions stay true. • Full, or vertical only. Skewed facades are squared too, not just converging verticals. • Not just buildings: billboards, posters, whiteboards and artwork straighten automatically as well. • Manual Fix for anything the automatic pass cannot read. Drag four corners onto the subject and it flattens square. • Decide what happens to the empty corners: keep them, fill them, or cut them off. Trim sky and foreground too. • Straighten, Crop, Perspective and Adjust in an editor in the style of Photos. Press and hold to compare before and after. • Pick several photos and move between them with the strip under the photo. • Works inside the Photos app as an extension. No exporting, no duplicates. DOCUMENTS • Scan with the built-in camera, one shot per page. AutoAlign finds the page, then crops and straightens it. • Or add pages from Photos and Files. • Every document gets a title and a category, from the on-device model of Apple Intelligence where available: receipts, bills, cards, notes, slides, letters, IDs, or your own. • Search by any word on the page, who sent it, or where you scanned it, in the app or from Spotlight. • Share any document as a searchable PDF. • Date, place and camera are kept on every page. ASK DOCUMENTS, WITH APPLE INTELLIGENCE (EXPERIMENTAL) Ask in your own words: "what was the total on the Hofer receipt?" The answer comes with the document it came from. Nothing is sent anywhere. Uses the on-device model of Apple Intelligence; needs a supported device with Apple Intelligence turned on. Works best in English. WHAT IT KEEPS • HDR. The gain map is corrected alongside the photo, so brightness and colour survive intact. • EXIF, GPS, timestamps and camera settings. • Your original. Every edit is revertible from the Photos app. PRIVATE BY DESIGN No account, no tracking, no analytics. Your photos and documents are processed and stored on your device. LANGUAGES English, العربية, Deutsch, Español, Français, Nederlands, 简体中文. FREE AND PREMIUM Free: the full correction, Manual Fix, cropping, and up to 4 documents. Exports carry a watermark, and photos save at reduced resolution. Premium: full-resolution and HDR export, no watermark, unlimited documents. Monthly, yearly, or a one-time purchase. MADE FOR Architecture, real estate, interiors, cityscapes and travel. Posters, whiteboards and artwork shot at an angle. And the receipts, letters and cards you need to keep. NOTE Automatic correction works best where the scene has clear straight edges. Where it does not, Manual Fix always does.

Developer will not honor this, so I will not support the developer. ### 1/5 — No Free IAP *2025-10-03* Tried to take advantage of the free lifetime IAP but it would not work. **Developer response:** Sorry to hear you couldn’t get the free lifetime IAP on time days after when the offer had expired. It was only valid until 30th Sept which the post had clearly mentioned. The app however is free to use and you just get a low res image which is still optimised for mobile viewing with a watermark added on it. I request you to kindly rate the app according to its strengths and weaknesses. That’d be very helpful for us to improve the user experience in the future updates. ### 5/5 — Magic perspective fix *2025-09-30* It doesn’t always work, but when it does it’s like magic. So much easier and faster than fixing up the perspective manually. **Developer response:** Thanks a lot for your review. Hope you enjoy using our app. ## Frequently asked questions about AutoAlign ### How does Auto Align fix leaning buildings?
