Fossy Protokoll helps tenants in Germany keep a verifiable record of defects in their flat: noise disturbance, mould, heating failures and more. From the recorded occurrences it builds a protocol covering a chosen period, and a factual defect notification addressed to the landlord. Both can be saved and shared as PDF or Markdown.
