Here's what a protected voice call looks like

01

Before it rings

A call comes in. Hiya has already checked it against the other one billion calls we've seen that same day. Spam doesn't ring. Scams don't get through.

02

When it rings

The phone doesn't just say “Unknown caller.” It shows you who's calling and why. Recognized callers get answered.

03

During the call

Hiya stays on after the pickup, checking for what people can't catch: a cloned voice, a scam in progress. You get alerted in real time.

04

After the call

This call just made the next one safer. Everything Hiya learned feeds back into the system, for every network, every business, and every person on it.

Why the world's biggest networks choose Hiya
