Sound ID · Baro

About this app

What you hear never leaves your phone. Sound ID turns your phone into a private ear. It listens through the microphone and names the sounds around you — a doorbell, a knock, a smoke alarm, a crying baby — entirely on your device. No internet. No account. No tracking. You can prove it: switch on airplane mode and it keeps naming sounds. Nothing is ever recorded or uploaded. Built first for Deaf and hard-of-hearing users, and genuinely useful for anyone who wants to feel safer at home. A mic that listens to your whole home should answer to you alone — so it does. PRIVATE BY DESIGN (THE WHOLE POINT) • Audio is processed in memory and discarded frame by frame — never saved, never sent. • Sound recognition runs 100% on your phone. Nothing goes to Google, to any cloud, to anyone. • Zero analytics, zero telemetry, zero third-party SDKs. No account, no login. • Privacy label: Data Not Collected. Verifiable in airplane mode. THE PAYOFF • Names the sound, big and clear — the top sound shows in huge letters with a confidence percentage, so you know at a glance what just happened and how sure the app is. • A rolling list of recent sounds with timestamps. Share it as plain text in one tap — handy for letting family know what's been going on. • A focused, high-value sound set: alarm, doorbell, knock, baby crying, dog, running water, smoke / CO alarm, phone, siren, speech, vehicle, music, applause, shouting, breaking glass. The sounds that matter for safety, not noise. YOU'RE IN CONTROL • One large sensitivity slider: turn it up to catch faint sounds, down to avoid false alerts. Your setting is remembered. • Teach your own sounds: record your doorbell or your microwave, test that it is really recognized, name it, and it sits alongside the built-in set. The audio is discarded as always — only a numeric fingerprint stays on this phone. • Watch only what matters: a switch for every sound, plus "Essentials only" and "All sounds" in one tap. The fewer sounds you keep, the harder they are to miss. • Keep listening with the screen locked. A doorbell or alarm posts a lock-screen notification and a vibration — audio still never leaves this phone. • Honest about its limits — if the on-device model isn't installed, Sound ID says so plainly and never invents a detection. What it shows, it actually heard. BUILT TO BE ACCESSIBLE • Every button is at least 64 x 64 pt. AAA contrast on an AMOLED-friendly black background that sips battery. Minimum 24 pt text. No double-taps, no swipes, no hidden gestures — just tap. GREAT FOR Deaf and hard-of-hearing people who want a visual cue for important sounds; parents listening for a baby in another room; anyone who wants to know if the smoke alarm, doorbell or phone is going off; people who refuse to put an always-on mic in the cloud. NO SUBSCRIPTIONS, NO ADS No subscription, no in-app purchases, no ads, no account. That's the whole deal. Part of the Baro family — The tools you reach for first.

Fixed vibration alerts set to 2x or 3x so they now pulse the full number of times. Previously the pulses were spaced too closely and merged into what felt like a single buzz.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
