A planned mobile app that classifies mysterious household sounds on the device itself, without accounts, cloud processing, or audio uploads.

Landing page captured for the 2026-08-28 issue.

Field notes

The proposed workflow combines continuous on-device classification with movement through a room: users follow the changing loudness, inspect a ranked result, and can save the session. The homepage describes 25 residential sound classes grouped into seven categories, including plumbing, HVAC, electrical, and biological sounds. It specifies YAMNet-based inference through Core ML on iOS and TFLite on Android, with optional exports containing logs, timestamps, and confidence scores rather than automatic uploads.
