Hearing alerts that actually matter.
Sound alerts you can see — built for deaf and hard-of-hearing iPhone users.
Nora listens for the doorbell, the smoke alarm, the kettle, the baby — and lets you know with a flash, a buzz, and a banner on your screen. No more guessing what you missed.
Three steps. No headphones. No setup headaches.
Nora uses Apple's on-device sound recognition to identify what she hears — and lets you know the way that works for you.
She listens
Open Nora and tap start. Your iPhone's microphone listens for over 50 everyday sounds — quietly, in the background.
She recognises
The moment Nora hears a knock, alarm, or alert, on-device AI matches the sound and confirms what it is — in milliseconds.
She tells you
The screen flashes, your phone vibrates, and a banner shows you exactly what was heard. You'll never wonder again.
Built for the moments that matter most.
Designed by someone with hearing loss, for people who shouldn't have to miss a thing.
60+ sound types
Doorbells, smoke alarms, knocking, baby cries, sirens, kettles, dogs barking, glass breaking, and dozens more — across 11 categories.
Visual flash alerts
The full screen flashes the moment a sound is detected — impossible to miss, even from across the room.
Custom vibration patterns
Different sounds get different buzz patterns, so you can tell a doorbell from a smoke alarm without looking.
Alert history
Review every sound Nora heard, with timestamps and confidence scores. Useful for spotting patterns at home.
100% on-device
Audio never leaves your iPhone. No cloud, no recordings, no listening servers. Privacy is the default.
Works offline
No internet needed. Nora works on a plane, in a basement, in a power cut — wherever you are.
If you've ever missed a knock, this is for you.
Deaf & HoH adults
Hearing aid wearers, cochlear implant users, and anyone navigating a hearing world.
Parents
Sleep through the night and let Nora wake you when the baby cries.
Anyone home alone
Take off your hearing aids without missing the doorbell or a smoke alarm.
Service dog handlers
A backup or stand-in for hearing assistance dogs when they're off duty.
Your sounds never leave your phone.

- No audio is ever recorded or stored.
- No internet connection required to listen.
- No accounts, no tracking, no third-party SDKs.
- Built on Apple's SoundAnalysis framework.

Most accessibility apps charge $5–$15 every month. We don't think that's right.
Made by someone who's been missing the doorbell her whole life.
I'm Emma, and I've had sensorineural hearing loss since I was a child. Severe in the high frequencies — the kind that makes consonants disappear and doorbells slip past unheard.
For years I relied on hearing aids, my partner, my service dog Smokey, and a lot of "what did you say?" Then I realised: my iPhone has a microphone, an AI chip, and is already in my pocket. So why couldn't it be listening too?
Nora is the app I wished I'd had ten years ago. Built privately, on-device, and priced like an accessibility tool should be — not like a SaaS subscription.
