About

LetterMinder

Paper mail still decides a lot: a tax notice, a letter from your insurer, a bill, an appointment. LetterMinder helps you keep track of what each letter asks of you. HOW IT WORKS 1. Scan a letter with the camera, or import a photo or a PDF. You can also share a PDF to LetterMinder from another app. 2. LetterMinder reads the text on your device and suggests the sender, a short summary, the task, the deadline and details such as an amount or account number. 3. You check the suggestion against the letter, change what needs changing, and save. 4. The task appears in your list, sorted by deadline, and LetterMinder can remind you before it is due. 5. When you are done, check it off and keep the letter in the archive, or delete it. FOLDERS Keep letters and tasks that belong together in folders, for example taxes, insurance or your business. Each folder shows how many tasks are open and the next deadline. When a new letter comes from a sender you have filed before, LetterMinder suggests the same folder. Give each folder its own color to find it at a glance. YOU STAY IN CONTROL Suggestions can be wrong or incomplete. That is why nothing is saved until you have confirmed it. For every deadline LetterMinder shows where it comes from: the passage in the letter, or a calculation such as "letter date + 14 days". Always check against the original letter. PRIVATE BY DESIGN โ€ข Your letters are processed and stored on your iPhone or iPad. โ€ข No account, no server, no tracking, no advertising. โ€ข Text recognition and suggestions run on the device. โ€ข You decide whether your letters are part of your device backup. FIVE LANGUAGES The app is available in English, German, French, Spanish and Italian and reads letters in all five languages, whichever language you use it in. If a letter is in a different language than the app, for example a German letter while you use the app in English, LetterMinder can translate its text on your device. WORKS ON IPHONE AND IPAD On iPad, your list and the open letter appear side by side. With Apple Intelligence turned on, suggestions are more detailed and include a summary. On other devices LetterMinder suggests the task, the deadline and payment details from the wording of the letter. Either way, you check every suggestion before it is saved. LETTERMINDER PREMIUM (ONE-TIME PURCHASE) The app is free for up to 10 stored letters. Premium is a single purchase, not a subscription: โ€ข Store as many letters as you like. โ€ข Your tasks appear in Apple Reminders, and tasks with a deadline show up in Apple Calendar. Check them off there or in LetterMinder. IMPORTANT LetterMinder is a helper for your paperwork. It does not give legal, tax or financial advice, and it cannot guarantee that a deadline is recognised correctly. You remain responsible for your deadlines and payments.
