How Momentum works

Say it once.
It carries the rest.

01Say it

Hold the mic. Momentum pulls out who, when, and what it’s about, and matches the name against your real contacts. No signal? The on-device parser still gets it.

02It preps you

Before the call, the card surfaces your last note about this person and up to three talking points on the topic you named.

03It closes the loop

Hang up and Momentum asks for a note and when to talk next. People you’re drifting from surface on their own — once, gently.

Thursday. Two calls and an errand.

Hold to talk, or type…
The part people stay for

Or let it be your phone app.

Make Momentum your default dialer and it handles the whole call: incoming ring, in-call keypad, hold, merge, conference. Block a number and it auto-declines. Every call lands in a recents log that knows who it was and when to call back.

You can hand the role back to your old dialer in one tap.

One idea, two products

Pingbox builds software where the conversation ends in something happening — not in a reply.

Momentum does that for your own day. Relay does it for your customers’.

Pingbox for Brands

Turn every inquiry into a decision.

Service brands spend thousands driving traffic that arrives, asks one question, and leaves. Relay answers on your site, WhatsApp, Instagram, and SMS with a tappable block — a service card, a booking flow, a live quote — built from your own catalogue and pricing.

FAQ

Everything else you’d want to know.

Free for everyone in the beta. Beta users get notice and a founding price before that changes.

Yes. Every AI path falls back to an on-device parser that handles times, dates and names. No key, no network, still works.

Contacts are read on your device to match names to numbers. Notes and call history stay on your phone, and Momentum never writes back to your address book.

Most single locations are live the same business day. Multi-location rollouts are one deployment, with each location overlaying its own pricing, hours and staff.

It answers only from documents you approve, with guardrails you set per location and per channel. Any response category can be flagged for human review before it sends.

Get Momentum first.

Join the beta and we’ll send you a build. Free while it lasts.
