A mobile app that lets tenants photograph and log property issues with timestamped evidence, automatically identifies the likely cause and severity (e.g., mould risk assessment from photos), and generates jurisdiction-appropriate formal repair notices to landlords. The tool tracks landlord response times against legal deadlines and escalates with template letters to housing authorities or environmental health officers when landlords fail to act.

Post-pandemic awareness of indoor air quality and mould health risks is at an all-time high, while housing affordability pressures keep more people renting longer. Tightening tenant protection laws across the UK and EU (such as the UK Renters Reform Bill) create demand for tools that help tenants exercise their expanding rights.
