Features
What Fristo can do.
A letter from an authority, an invoice or a notice from your insurer: Fristo helps you understand what it says and what to do next.
Scan a letter or import photos and PDFs. Fristo finds the important details, organizes your mail and reminds you of deadlines.
Deadlines & reminders
Due dates, amounts, IBANs and reference numbers in one clear view. Reminders before the deadline and on the due date – mark a letter done or snooze it right from the notification.
Pay with a GiroCode
Copy payment details with one tap or scan the QR code with many banking apps: recipient, IBAN and amount are filled in.
Done, step by step
Check off each task in a letter and see your progress. Change the priority, category or icon – even with your own emoji.
Your mail in order
Search your archive by sender, text or reference, filter by category or status, add notes, and open the original pages or share them as a PDF.

Frequently asked
Where can I get Fristo?
Fristo has been on the App Store since November 2, 2026, and on iPhone and iPad since version 1.3.
What’s free, and what does Fristo Pro add?
You can try Fristo with three letters for free. Sample letters don’t count, and deleting letters doesn’t give free letters back. Unlimited letters¹, Ask Your Letter¹, reply drafts¹, app lock¹ and exclusive designs¹ need a Fristo Pro subscription. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period; you manage them in your Apple Account settings.
Do my letters leave my device?
No. Text recognition and AI processing run on your device. Fristo doesn’t upload your letters to a server of its own and needs no account or bank login. With Fristo Pro, they’re also kept in your private iCloud¹. Details are in the privacy policy.
What do I need for the AI features?
AI questions and individually generated replies need a compatible device, Apple Intelligence turned on and an available language model. Without it, Fristo uses rule-based recognition, and editable reply templates are available.
Does Fristo replace legal advice?
No. Fristo doesn’t replace legal, tax or financial advice. Text recognition and AI can make mistakes, so always check important deadlines, amounts and payment details against the original letter.
Which devices and languages are supported?
Fristo runs on iPhone and iPad with iOS or iPadOS 26 or later. The app is available in German and English (US); the language of the explanations can be set separately.
With Pro, including all future updates and new features at no extra cost, as soon as they’re available.
