Who WonderBon is for

Three worlds. One solution.

How it works

How the household budget app works.

Capture receipts, categorise spending automatically and split costs fairly — without manual data entry.

01

Photograph the receipt

Whether receipt, PDF or screenshot. By smartphone, from your Mac via drag & drop, or straight from the clipboard.

02

WonderBon reads everything

Every product, every price, every category captured automatically. No more typing things in.

03

Split it fairly

Per line item or as a lump sum. At the end of each month WonderBon shows who owes whom how much — or that everything's settled.

Features

Everything you need.
Nothing you don't.

AI recognition

Snap the photo. Done.

WonderBon recognises products, prices and categories on every German receipt — even crooked phone shots and faded thermal paper.

Frequently asked

Everything you want to know.

Is WonderBon a household budget app? +
Yes. WonderBon is a household budget app that lets you scan receipts, categorise spending automatically and split shared costs fairly. Unlike classic household budget apps, WonderBon recognises individual products on each receipt.
Who is the household budget app for? +
WonderBon is for couples, flatshares, families and individuals who want to understand their spending better and settle shared expenses transparently.
Does WonderBon work without bank account integration? +
Yes. WonderBon works without connecting to your bank account. You capture expenses via receipts, invoices, PDFs or screenshots and still keep an overview of categories, receipts and shared costs.
How accurate is the AI at reading my receipts? +
We use Claude by Anthropic — one of the most advanced AI models in the world. On typical German receipts, recognition runs at around 98%. Even crooked phone shots, faded thermal receipts or PDFs from online shops are captured correctly. If something is off, you can fix it in a single click.
What happens to my data? +
Your data is stored on German servers (Strato) in line with GDPR. Receipts are sent to Anthropic for recognition but are not used for training purposes. You can export all your data at any time or delete your account entirely.
Can I use WonderBon on my own? +
Absolutely. While most plans cover several people, you can use WonderBon solo — the split features are optional. Many people use WonderBon simply as a digital receipt archive and spending overview.
Does it also work with non-German receipts? +
WonderBon is currently optimised for the German market. Receipts in English, French or Dutch are usually recognised correctly too — though category assignment may vary. We're working on official multi-country support.
