Rents, payments, receipts and handovers in one app. Photograph invoices and rental agreements, the AI fills in the details, you check and accept.
Free for one unit · iPhone & Android · Servers in the EU · Plain language instead of jargon
For flats, commercial units (including with VAT), garages, parking spaces and furnished lettings.
Buildings, units, tenants and tenancies set up in four steps, with history and all documents in one place.
Base rent, advance payments and surcharges with “valid from”, graduated rent with a preview, due on the nth business day or on a fixed day.
The amount due is created every month on its own, prorated to the day when tenants move in or out. The app recalculates rent reductions and changes.
Import your bank statement as CSV, first for Sparkasse, other banks with a one-time column mapping. The app matches incoming payments and allocates them according to §§ 366, 367 BGB (German Civil Code).
Missing rents appear on the home screen and as a notification. For the tenant there is a friendly text to share.
Move-in and move-out room by room with condition, defects, photos, meter readings, keys and both signatures. The PDF is created on the phone, even in the basement.
All receipts with the original, filterable by property, year, cost type and “Can I pass this on to the tenant?”.
Coming soon: partners and co-owners work in the same account, with several owners per property.
Per property and year as PDF, Excel and all receipts as ZIP, laid out like the portals and forms of your metering service provider (ista, Techem, Brunata-Metrona, Kalo, Minol), and for your tax return too.
The scan button in the middle takes invoices, receipts and rental agreements, via the camera, from your photos or as a file.
One receipt or a whole stack in a row, for example to catch up on a full year.
Supplier, amounts, period, cost type and property. For a rental agreement: property, units, tenants and rent.
Nothing is saved without your confirmation. Every suggestion lands on “Check & accept”.
The file is attached to the receipt or agreement and can be opened at any time.
The AI runs at DeutschlandGPT in the EU and only with your consent, which you can withdraw at any time. MietGenius reads e-invoices (XRechnung, ZUGFeRD) and CSV bank statements without AI.
“Can I pass this on to the tenant?” instead of “allocable under § 2 BetrKV”. We show the technical term in small print below.
The AI makes suggestions, you decide. What has been paid stays paid, overpayments become credit.
Your account is stored on our servers in France, the AI runs in the EU. You can delete the account in the app at any time.
The plan depends on the number of your flats and commercial units; garages and parking spaces don't count. Every plan includes all features.
All prices include statutory VAT; every subscription is also available as an annual plan. You subscribe and pay via the App Store or Google Play. The subscription renews automatically unless you cancel it before the end of the term (in the App Store at least 24 hours before). You can cancel at any time in the subscription settings of the App Store or Google Play; the subscription then runs until the end of the paid period.
MietGenius launches in Germany, with Austria and Switzerland to follow. We welcome questions and suggestions by e-mail.
