Now testing with the D/HH community in London

All ears,
no worries.

TactiCall turns the sounds in your home into something you can feel, no rewiring, no flashing lights bolted to every wall, just a wristband that knows your doorbell from your dog.

Built with and for the deaf and hard-of-hearing community. Not a medical device: just a better way to stay in the loop.

How it works

Sound in, touch out.

Your phone listens, TactiCall's model figures out what it heard, and your wrist gets a tap that tells you exactly what's going on, even with your hearing aids off.

1. It listens

Your phone's mic picks up the everyday sounds of your home, no extra hardware bolted to the wall.

2. It understands

On-device AI matches what it hears to a sound you've taught it: doorbell, alarm, your name, whatever matters to you.

3. You feel it

A distinct vibration pattern on your wrist tells you which one it was, no glance at a screen required.

Sounds everyone shares

Doorbells, fire alarms, phones ringing, the classics sound roughly the same everywhere, so TactiCall can recognise them out of the box.

Sounds that are yours

Your cat; your kid yelling from upstairs; your specific microwave beep. Record a few samples and TactiCall learns to notice them too.

Why it's different

Not a Ring doorbell replacement.

Most assistive devices solve one room. TactiCall moves with you, which matters more than it sounds.

No.1

Every room, no wiring

One phone covers the whole home. No flashing-light units to install and re-install every time you move.

No.2

Goes where you go

Travelling, staying at someone else's place, a hotel for the weekend: it's on your wrist, not bolted to a wall.

No.3

Processed locally

Audio is classified right on your phone, no internet connection needed. So even if your wifi drops or you're somewhere with no signal, you still feel the tap on your wrist.

The research

We tested it before we talked about it.

TactiCall grew out of academic research at University of the Arts London, peer-reviewed and presented at the International Conference on Social Robotics + AI, 2025.

Vibration patterns correctly identified by participants (pilot study, n=16) 96.9%
Confidence threshold required before the on-device model commits to a label 83%
User samples needed to teach the model a new sound 5
Hours of in-depth conversation with D/HH households so far 20+
Published research: Niu, H., Akhond, S., & Samani, H. "TactiCall: ML-Powered Haptic Wristband for Alerting Hearing-Impaired Users." Lecture Notes in Computer Science (LNAI), Springer Nature, ICSR+AI 2025.

The pilot study tested pattern recognition with hearing participants in a controlled setting; we're now running it with D/HH households, that's the work in progress right now.
Good questions

Before you ask

Do I need an Apple Watch or a special device?+

The app works on most smartwatches with a vibration motor. We're also building a dedicated wristband for anyone who'd rather not wear a smartwatch, it's in development now.

What will it cost?+

We're aiming for roughly £80 one-off for the dedicated wristband, plus £3-5/month for the app and its ongoing sound recognition. Final pricing isn't locked in yet; the waitlist is the best way to hear first.

Is this a medical or assistive device I have to register?+

No. Think of it more like AirPods than a hearing aid: a piece of consumer electronics anyone can wear, with no paperwork attached.

Does it listen to everything I say?+

No. It's listening for sound events (a doorbell, an alarm), not conversation, and classification happens on your own phone; audio isn't sent off for processing.

When can I actually get one?+

We're finishing technical validation now, with an MVP planned for testing by the end of 2026 and a UK launch to follow in 2027. Join the list and we'll only email you when there's real news.
