The best flatshare app in the world

Snap the receipt, everyone ticks their items, done 💸

Spießer is my side project for flatshares, or as Germans say, the WG. Made for international flats: each flatmate uses the app in English or German, the numbers stay the same. Less money stress at the kitchen table, with a pinch of Ruhr-area charm 🥔

Into beta testing? Clever foxes, the sign-up is further down.

Why Spießer?

Glad you asked. A taste of what is already in the app, all built around one goal: peace about money in your flat.

Snap it, don't type it

Snap the receipt, done. The app reads the shop, the date, every item and its price for you. Works with receipts from Rewe, Edeka, Lidl, Aldi, dm, the corner shop, you name it 😎 Five scans a day are free, and typing it in always works.

Pay only for what you actually use

"I don't even drink milk!" Fair enough. Tick only the items you actually use: your own stuff, shared stuff, anything goes. Fair to the cent. Unleash your inner penny-pincher 🦊

Fewer transfers, zero confusion

Spießer works out who owes whom and suggests as few payments as possible: at most one fewer than the number of people in your flat. PayPal gets a PayPal.Me link with the amount filled in. Bank transfer and cash work too.

German at heart, fluent in English

Made in the Ruhr area, built in Bremen. GDPR focus, core data in Frankfurt, no ads. Each flatmate picks English or German, so Erasmus students, expats and locals share one flat. No Silicon Valley vibes, just Granny's household book, only digital.

Roadmap: new features for your new favourite app

In the app you vote on what gets built next. Or how the buttons should look. Or which garden gnome is still missing.

Split costs by room size

"Bigger room, bigger share?" With the electricity bill, that was a running argument in our flat.

Holiday mode

Left out of new costs automatically while you sizzle on a beach somewhere

Automatic month-end settle-up

Rescues the brave souls who always pay up front

Export to CSV/PDF

For your tax return or for nostalgia. I don't need it myself, but maybe you do?

Import from Splitwise

Bring your old balances along when your flat switches. Until then: settle up once, start from zero.

Statistics and recurring costs

Live since version 1.3: see what your flat spends money on, and internet or streaming add themselves.

Questions & answers

Most of them, yes. Rewe, Edeka, Lidl, Aldi, dm, Rossmann: all tested. If a receipt is in really bad shape (crumpled, faded), you may have to fix a few lines, and an AI feature already helps with that. Even then it beats typing everything in by hand.

Ideally yes, then everyone sees their own balance. If someone has not joined yet, add them as a placeholder with a name and email and split with them anyway. Once one flatmate is on board, the rest usually follow.

Yes. Spießer is on the App Store and Google Play. New features get tested with real flats first. Sign up for the beta and we will let you know when the next test starts.

No data sales, and core app data is mostly stored in Frankfurt (Firebase). Receipt recognition runs through Microsoft Azure in Germany. Not everything stays in the EU: sign-in runs through Firebase Authentication, and hard-to-read receipts may be sent to the OpenAI API for correction. Receipt photos are stored so your flat can trace a purchase. Details are in the privacy policy.

Absolutely. Spießer is built for flatshares, but it works just as well for couples, families or a weekend trip. Anywhere costs get shared.

PayPal with a ready-made PayPal.Me link, bank transfer, cash, or something creative like "I'll do the dishes". The money moves outside the app, Spießer just keeps the books.

For flatshares Spießer, for trips abroad Splitwise. The free version of Splitwise limits entries per day, and receipt scanning and itemised splitting are part of the Pro subscription. Spießer does exactly that for free and without ads: snap the receipt and split it item by item (who drinks the milk, who does not). The catch: Spießer is still young and supports one flat per person. More in the Spießer vs. Splitwise comparison (in German).

Yes, Spießer. Free, no ads, from the Ruhr area, built in Bremen and made for flatshares: snap the receipt, split it item by item, core app data mostly in Frankfurt. Splitwise only scans receipts in its paid Pro plan, Spießer gives you five free scans a day. Available for iPhone and Android, in English and German.

You snap the receipt in the app. Our AI (OCR, so text recognition) reads the shop, the date, every item and its price. Then you get a checklist: everyone in the flat ticks only the items they wanted, and the rest is split automatically. It works with most supermarkets and drugstores. If a receipt is hard to read, you can fix lines by hand.

Just show them on the next shop: snap the receipt, assign the items, done. "Everyone pays only for what they wanted" usually wins the argument on the spot. Your flatmates only need to install the app and join the flat. No need to convince anyone up front, the first shared shop does that for you.

Yes. Everyone picks their own language: Spießer follows your phone's system language, and you can switch it in the app settings. The flat, the amounts and the balances are the same for everyone, only the buttons and menus change. German receipts are read just the same. More in Spießer is now in English.

Right now Spießer is made for flats in Germany: amounts are in euros and receipt scanning is tested with German supermarkets. Flatshares in other European countries are next on the list. If you live in one, write to us and tell us where. The plan is in From WG to coloc.
