Rechnung | Scan & Save
Scan a receipt, save it and find it again when you need it. Rechnung is a free Android app that keeps receipts and expenses organised in one place.
About the Project
Most of my work is in data analytics, but I also enjoy building websites and apps. I started Rechnung | Scan & Save as part of Hope Intelligence, bringing together my interest in data and software development.
The idea is simple: instead of keeping paper receipts in drawers or searching through photos, you can keep the documents that matter in one place on your phone.
How It Works
Take a photo of a receipt or add it manually. The app recognises details such as the store, date and total. You can check and edit these details before saving. Later, you can find the receipt by date or category.
Features

- Check Before SavingReview recognised details and correct anything that needs changing.
Keep Documents for Taxes, Warranties and Returns
In Germany, some receipts matter long after a purchase. You might need one for your tax return, a warranty claim or proof that a parcel was sent back. Rechnung helps you keep those documents together, ready when you need them.
A Handy Personal Archive: The app helps you keep receipts organised, but it does not replace tax advice or any legal record keeping obligations.
Free, No Subscription
Rechnung is designed to make receipt management accessible to everyone. It is a free Android app that does not require a paid subscription.
Technology
I built the app with React Native and Expo, and I use TypeScript for the app logic and SQLite to store data on the phone. It combines mobile development with simple and useful ways to understand everyday spending.
What’s Next
Next, I would like to explore an iPhone version and a web app. Both are ideas for the future and are not part of the current Android app.
Available on Google Play
Rechnung is on Google Play. If you use Android, I would be glad to hear what works well and what could be better.
