What's New in AutoAlign

4.0.2

October 5, 2026

AutoAlign 4.0 keeps your documents, and answers questions about them with the on-device model of Apple Intelligence. • Documents. Scan receipts, letters, cards and slides with the built-in camera, one shot per page, or add them from Photos and Files. Every page is found, cropped and straightened for you, then titled and filed by type, using the on-device model of Apple Intelligence where available. Make your own categories too. • Find anything. 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. • Ask Documents (experimental). Ask in your own words, like "what was the total on my last receipt?", and get the answer with the document it came from. Uses the on-device model of Apple Intelligence, so nothing leaves your iPhone. Works best in English. • A new editor in the style of Photos: Straighten, Crop, Perspective and Adjust, now with brightness, contrast and saturation. Press and hold to compare. • Several photos at once. Pick a set and move between them with the strip under the photo. • Date, place and camera are kept on every scanned page.

No Free IAP

Tried to take advantage of the free lifetime IAP on the day it was available but it would not work. Developer will not honor this, so I will not support the developer.

Response from developer

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.

Magic perspective fix

It doesn’t always work, but when it does it’s like magic. So much easier and faster than fixing up the perspective manually.

Response from developer

Thanks a lot for your review. Hope you enjoy using our app.
