Decibel vs EchoFind

Decibel Detector is a clean, free sound level meter for iPhone. Open the app and instantly see how loud your surroundings are, in dB(A) — the same A-weighted scale used by professional sound level meters. A live ring meter and color-coded exposure bands help you understand whether you are in a quiet space or somewhere that could damage your hearing. Features • Live dB(A) readings with industry-standard A-weighting • Color-coded exposure bands from Quiet to Dangerous • 85 dB hearing-safety indicator — the level where extended exposure can begin to harm hearing • 100% on-device: audio is never recorded, stored, or sent anywhere • No ads, no in-app purchases, no account, no tracking Readings are estimates for everyday awareness and are not a substitute for a certified, professionally calibrated sound level meter.

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.
