At move-out, a sudden dispute over scratches that were already there when you moved in?
Every defect.
Documented as proof.
At a flat handover, what counts is what you can prove. MängelLog creates your handover report right on your phone: every defect with photo and timestamp, plus meter readings, keys, witnesses and the signatures of tenant and landlord. Everything stays offline on your device.

PDF report to share
A professional PDF report with all photos, defects and signatures, shareable by email (one-time purchase).
Why you should document the handover yourself
You move into a flat and spot scratches, stains or loose tiles that were already there. At move-out, the landlord claims they are all new and wants to keep part of your deposit. Without dated photos, it is your word against theirs. That is exactly what MängelLog is for: your handover report that records the condition of the flat while you can still see it.
You capture every defect with photo, room, location and category, each with an automatic timestamp. You also record meter readings for electricity, gas and water, log the keys, and have tenant and landlord sign right on the phone. On inspection day you have everything together — for move-in, move-out and interim checks.
All entries stay solely on your device. No account, no server, no cloud, no sharing. MängelLog documents the condition and, on request, turns it into a PDF report for the landlord or property manager; the app is not a substitute for legal advice.
Three situations tenants know
The meter reading no one wrote down
Without a meter reading at handover, you argue later about utility bills. With a photo, meter number and timestamp, the reading is clearly documented.
The deposit they want to keep
The landlord wants to keep part of the deposit for defects that existed before. Your complete report with photos and signatures shows the condition at handover.
All three situations share the same pattern: without your own documentation, every defect stays disputable. With a complete handover report, the condition of the flat stays verifiable when it comes to the deposit.
