Quittungsbuch
An offline-first cash-spending tracker built for German consumers who want to keep using cash, with a community-mapped directory of cash-accepting shops and ATMs so users can find places that still take notes and coins.
German consumers who actively want to keep paying cash and tracking those payments
- Manual receipt entry in under five seconds — amount, category, photo of the receipt, all stored locally
- Crowd-sourced map of shops, restaurants, and markets that accept cash, with a 'verified cash-friendly' badge for confirming buys
- ATM and bank-branch finder with up-to-date counts and recent-user reports of cash availability
- Weekly cash-flow summary that helps users see how much they're funneling through card networks vs. paper
Bargeld is trending in Germany because consumers noticed ATMs disappearing, shops going card-only, and EU rules shifting — and the BR24 piece shows the public is hungry for tools that keep cash practical rather than treating its decline as inevitable.
Bundesbank 2025 study shows 55% of purchases already cashless (so 45% still cash) with a real Bundestag/public debate ('Bargeld muss bleiben') covered by Focus, NDR and Bundesbank Monatsbericht; demand exists but is structurally shrinking.Zahlungsverhalten in Deutschland 2025 | Deutsche Bundesbank ↗Debatte über Bargeld und Potenziale von - Deutscher Bundestag ↗
Crowded 'Haushaltsbuch' category with many competitors (CashOwl explicitly offline-first, plus Finanzguru, Outbank) and dedicated cash counters (Bargeldrechner, CashCounter); community cash-accepting shop/ATM directory angle isn't validated as a gap and could be replicated via OpenStreetMap.CashOwl — Haushaltsbuch mit Weitblick ↗Beste Haushaltsbuch-App 2026 im Test | Financer ↗
Category is dominated by free/freemium Haushaltsbuch apps (Handelsblatt, Wiwo, Finanzfuchs comparisons emphasize free options); niche single-purpose utility with weak willingness to pay.5 kostenlose Haushaltsbuch Apps im Vergleich 2026 - Handelsblatt ↗Die besten Haushaltsbuch Apps 2026 im Vergleich ↗
Bundesbank 2025 confirms 55% cashless and rising trend; even with political pushback the secular direction is toward less cash, eroding the addressable problem over time.Zahlungsverhalten in Deutschland 2025 | Deutsche Bundesbank ↗Verschwindet das Bargeld nach und nach aus unserem Alltag? ↗
Offline-first cash tracker is straightforward (matches CashOwl pattern); the community-mapped shop/ATM directory needs network effects, moderation, and ongoing data curation which is the hard part.CashOwl — Haushaltsbuch mit Weitblick ↗
