The free Hongi app

Check it’s really Mum before you send the money.

A familiar voice is easy to fake now. Pair once with the people you trust; on any call, you each read a different word. If both match, it’s really them.

Illustration of the ritual: each of you reads a different word.

How it works

Pair once. Check on any call.

Pair once

Scan each other’s QR code when you’re together, or send an invite link when you’re apart.

Read your words

On any call, each of you reads a different word. The words change every 30 seconds.

Match, or hang up

Both match: it’s really them. No match: hang up and call back on a number you know.

The Hongi directory

Check your bank’s calls, too

Organisations in the Hongi directory are vetted: Hongi checks their web domain and reviews their logo and official numbers. Add one once; when they call, you read your code and they read theirs back.

You stay pseudonymous: no account, and the organisation never learns your name, number or contacts.

No account. Hongi is never part of your call, and the secret you share with someone stays on your two phones.
