Scan-A-Lot turns one photo of many documents into separate scans. Lay your receipts out on a table and take one picture. The algorithm finds each receipt, then crops, straightens and flattens it. Save them as separate files, or combine them into one PDF. No more scanning them one at a time. It works great for letters, school forms, recipes and cards too! You can even automate it with Apple Shortcuts! • Finds every document, even tilted or shot at an angle. Missed one? Just tap it. • Drag a corner to adjust a crop, or rotate a document. • Black-and-white, grayscale and color filters, for every page or one at a time. • Save documents as images or PDF files to Files or Photos, or share them to any app. • Shortcuts: "Split Photo into Documents" splits a photo without opening the app, or opens it so you can check the crops first. • Runs on iPhone, iPad and Macs with Apple silicon. On iPad, use keyboard shortcuts, drag and drop, and multiple windows. • Everything happens on your device. No account, no ads, no tracking and no subscription. (Scan-A-Lot makes images and PDFs. It doesn't read the text on your documents or add up your receipts.)

Verdict

The call

The clearest difference is price: ChatGPT at Free against Scan's $2.99. ChatGPT also leads on ratings volume (12M vs 2) and chart position (#1 vs unranked). Scan's advantage is in-app purchases (none vs 9) and ads (none vs shown). On rating and device support there is nothing between them.
