Mappenform turns your details into a complete German rental application (Wohnungsbewerbung): cover letter, cover page and tenant self-disclosure (Mieterselbstauskunft) in one designed PDF. No account, your data and documents stay in your browser. Free for one person. A one-time 19.90 € upgrade adds couples and shared flats up to five people, more templates and merging your own PDFs such as SCHUFA or payslips. The interface is German, because the landlords are.
