iPhone
Get a visual alert when an important sound happens — doorbell, alarm, siren. Recognition runs on your phone; no audio ever leaves it.
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.
• The screen stays awake while you listen, so you can set the phone down and wait for the doorbell. Detection runs while that screen is on — there is no background listening, and the app tells you so instead of stopping quietly.
• 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.
