The creator wears a connected device during the event. As the moment unfolds, their real heart rate streams live to your screen, the same BPM they’re feeling, the instant they feel it. No replay, no simulation. When their pulse spikes, so does yours.

The live window closes and can’t be re-entered, that feeling only happens once. But the moment you were part of is saved to your collection: peak BPM, duration, and the full heartbeat trace, yours to keep and share.

Signal One is free on iOS and Android. As a fan, all you need is your phone, no wearable required. Only creators need a connected device to broadcast their signal (Garmin HRM600 or similar, Apple Watch, and Nordic Thingy).

The app is free to download. Access to a live moment starts at $5 and spots per event are limited, the scarcity is real.

Creators are athletes, performers, and artists who choose to share their pulse with fans. During our pilot phase, creator access is limited as we onboard our first partners.

A moderator is someone the creator trusts to run the live experience, opening and closing signal windows, managing transitions and stepping in with an emergency stop if needed. They protect the moment so the creator can stay focused on it.

Yes, on both counts. Creators choose exactly when their signal is shared and it’s only broadcast inside the windows they open, never continuously. As a fan, your own data is never shared with others. Authentic, consented connection is the foundation of Signal One.

We’re launching with a small set of pilot events soon. Download the app now to be ready when the next moment goes live.
