The parcel that arrived yesterday has a return window. The receipt in your bag has a warranty. Photograph either one right after you buy, the paper receipt as readily as the order confirmation still on your screen, and DueDog files it as a purchase with its deadlines. Contracts and penalty notices work the same way. Every one of them has a date by which you have to decide, and almost none of them reminds you. You confirm what the app read, the app reminds you in time. No upload, no account. PURCHASES Purchases are the everyday case. The list opens on All, the most urgent deadline first. Photograph the paper receipt, or take a screenshot of the order page in the shop's app and pick it from Photos. One image is enough. DueDog reads shop, date and amount; you pick the return window and the warranty from the usual options, and the app counts the days to the last one. The deadlines are always your choice: the app never claims to know what the law says. CONTRACTS Car insurance, broadband, the gym, the router you rent. Photograph the contract or the renewal letter, or share a PDF into the app. DueDog reads provider, start date, renewal and notice period, works out the real cut-off date and reminds you early enough to act: cancel, renegotiate, or let it run on because you decided to. FINES Photograph the penalty notice and confirm the day it arrived. From that day DueDog counts the days, shows the last day to pay or to challenge it, and reminds you a week, three days and a day before. You pick the deadline from the usual options; DueDog counts conservatively and is not legal advice. IN UNDER A MINUTE 1. SCAN. The camera, a picture from your library, or a PDF shared from Mail or Files. Text recognition runs for English, German and Spanish at the same time. 2. CONFIRM. The app shows what it understood, field by field, and marks which values came from the model. You fix whatever is off and save. Nothing is stored without your go-ahead. 3. GET REMINDED. Reminders before the day, and an entry in your calendar if you want one. NOTHING LEAVES THE IPHONE A receipt carries what you bought and what you paid; a contract carries your name, your address, your customer number and sometimes your bank details. DueDog sends none of it anywhere: text recognition and Apple's on-device language model both run on the phone itself. There is no server receiving your documents, because there is no server. No account, no analytics, no ads, no cloud sync. The privacy label says "Data Not Collected" because that is the only label that matches how the app is built. Scanning, analysing, saving and being reminded all work in airplane mode. THE AI SUGGESTS, YOU DECIDE The model reading your document is small and runs on a phone battery. It gets most things right and some things wrong: it can mistake the signature date for the start date, or read the wrong total off a receipt. That is why every result appears first as an editable suggestion and is only saved once you confirm it. Money rides on a deadline, so the last word is always yours. WHAT IT COSTS Scanning, saving and the standard reminders are free, for purchases, contracts and fines alike, with no limit and no subscription. A one-time lifetime unlock adds the month view, which answers what runs out this month; reminder points you set yourself; and the PDF export of your contracts and deadlines. If the app saves you a payment you no longer wanted, you can leave a tip from the settings. Tips are voluntary and unlock nothing. REQUIREMENTS DueDog needs an iPhone that supports Apple Intelligence, running iOS 26, with Apple Intelligence enabled in Settings. The language model is part of iOS, so there is nothing to download and no key to enter. Questions or problems: support@freshlab.es. We answer in English, Spanish and German. Please do not email us your documents; we do not need them to help, and we would rather not have them.

Verdict
The clearest difference is in-app purchases: ProofCase at none against DueDog's 4. ProofCase also leads on update cadence (daily vs every 5 days) and iOS requirement (17.0 vs 26.0). On price, ads and device support there is nothing between them.
