Your mum doesn't need an app.
She needs one number.

A familiar phone number that helps elderly and low-tech people reach family, carers and essential services — by simply speaking. No smartphone. No passwords. No QR codes. Just a call.

Incoming call — Tuesday 7:42am
"Hello… I feel a bit dizzy. Can you get Michael for me?"
"Of course, Margaret. I'm letting Michael know right now, and I'll connect you to him. Stay on the line with me."
→ Michael's phone rings in Bangkok. He picks up. Mum is through. Total time: 40 seconds.

How it works

The oldest interface in the world, made brilliant.

1

They call

One familiar local number, saved on speed dial or written by the phone. Landline or mobile — no data needed.

2

They speak

A warm, patient voice answers instantly and understands what they need — in plain language.

3

We route

Family gets alerted on WhatsApp, Telegram or LINE. The call is bridged to the right person's real phone — wherever in the world they are.

4

Everyone relaxes

If no answer, we try backups. Emergencies trigger hard-coded escalation. Every call is summarised for the family.

Real calls, real help

What people actually say

OneNumber isn't a chatbot. It's a router for human help — designed to understand, alert and connect in under 90 seconds.

"Call my daughter."Bridged to her current number — even if it changed last month.
"Remind me about my medicine."Gentle scheduled reminder calls, confirmed to family.
"Is this phone call a scam?"Scam-check support for the most targeted generation.
"I need a ride to the clinic."Routes to family, neighbour or local transport.
"I've fallen."Deterministic emergency protocol. Family alerted instantly. Local emergency guidance given.
"I just wanted to talk to someone."A patient voice that never rushes — and lets family know she called.
The honest comparison

Better than the button.

Emergency pendants only work when she falls, remembers to wear it, and someone eventually rings back. OneNumber answers every call, instantly, about anything.

The pendant she has now

Only triggers on a fall. Useless if she's dizzy, lonely, confused or being scammed. Has to be worn and charged. A call centre rings back "when they get around to it". £20-30/month for one function.

OneNumber

She calls about anything, any time — a fall, a worry, a reminder, a suspicious phone call, or just "get me my son". Family alerted in seconds, live call bridged in under a minute. The phone she's used for 50 years is the device.

The promise

Your elderly relative always has someone to call.

No tech required

Works on any phone made in the last 50 years. No app, no data plan, no literacy barriers.

Family in the loop

Alerts on WhatsApp, Telegram or LINE. Call summaries. Backup contacts. Spend caps you control.

Safety first

Hard-coded emergency phrases. Never pretends to be a doctor. Human fallback, always. Full audit trail.

Works anywhere

Built for rural Thailand, remote Australia, the British countryside — anywhere voice reaches but apps don't.
