EchoFind vs Sound Scope Analyzer

EchoFind helps you track down the mystery sounds in your home — the hum behind a wall, the buzz from an outlet, the rattle you can hear but can't find. IDENTIFY Tap once and EchoFind listens, then names what it hears from a library of common household sounds — appliances, motors, water, HVAC, alarms, and everyday ambient and human sounds. Classification runs entirely on your device in real time. LOCATE Can't tell where a sound is coming from? Start Locate and walk slowly through the room. EchoFind tracks your path with your phone's motion sensors and builds a simple heatmap showing where the sound is loudest — guiding you toward its source. PRIVATE BY DESIGN Your audio never leaves your device. There is no account, no sign-in, no analytics, and no tracking. Sounds are analyzed on your iPhone and discarded. Motion data stays on your device too. (See our privacy policy.) HONEST ABOUT WHAT IT CAN DO EchoFind reliably detects common ambient, biological, and human sounds. Detection of specialty mechanical, plumbing, HVAC, and electrical sounds is experimental in this release and clearly labeled as such in the app — treat those results as hints, not conclusions. NOT A SAFETY DEVICE EchoFind is an informational tool only. It is not a safety, diagnostic, or measurement device. If you suspect an electrical, gas, water, or fire hazard, stop and contact a licensed professional or your utility — do not rely on this app. Built for curiosity, not certainty. Point it at the unknown and start hunting.

Sound Scope Analyzer visualizes sound from your microphone in real time — an oscilloscope and spectrum analyzer in your pocket. ● Real-Time Mode • Watch waveforms like on an oscilloscope (a trigger keeps periodic waves steady on screen) • CRT-style afterglow effect you can toggle on and off • Frequency spectrum up to 24 kHz with automatic noise-floor removal, so real sounds stand out clearly • Fixed or auto scaling for each axis; pinch to zoom and drag to pan ● Timbre Mode • Automatically detects a sustained long tone (like singing “ahh”) and analyzes it with high frequency resolution • Shows the fundamental note name and frequency, with offset in cents • Marks each harmonic peak with its note name and measured frequency • Save the analysis result to Photos as an image • Sound source presets: voice, whistle, piano, guitar, bowed strings, and winds ● Great for • Long-tone practice and tone checks for winds, strings, and vocals • Comparing the harmonic structure of different instruments • Learning the physics of sound: frequency, waveforms, and harmonics • Exploring the sounds around you ● Privacy All audio is processed entirely on your device. Nothing is ever recorded, stored, or transmitted. Available in English and Japanese.
