Apartment Noise Logger
A community-driven, social mobile application allowing apartment residents to measure decibel levels, log noise disturbances with audio evidence, and connect with building neighbors anonymously.
The Core
Challenge.
Apartment tenants frequently suffer from noise disturbances but lack type-safe measurement tools, legal-grade PDF evidence generators, or private community groups to validate shared building issues.
Tactical
Resolution.
Engineered an offline-first Flutter application utilizing native microphone decibel monitoring and a zero-login onboarding flow. Integrated Firebase Firestore for secure cloud synchronization under an anonymous device UUID and Firebase Realtime Database for zero-latency building chat channels.
System
Capabilities.
Execution
Protocol.
Designed with an 'Anonymous-First' philosophy, the architecture avoids standard user registration. Instead, a unique device UUID is generated on first launch to map cloud-sync assets. The decibel reader consumes high-frequency microphone buffers, mapping them to real-time fl_chart components. For community engagement, we deployed Firebase Realtime Database to fuel zero-latency sub-channels partitioned by ISO country and state nodes.
