For fitness software platforms
Real-time heart-rate data for every class, delivered through one API.
PulseRelay streams live heart-rate data from any BLE device into your product. Create premium class experiences and performance insights in weeks — without building BLE, real-time, or mobile infrastructure.
Deliver the premium in-class experience — without building the plumbing.
Your platform stays in control of schedules, payments, and member profiles. We power the heart-rate layer: device connectivity, real-time streaming, aggregation, and a white-label participant app that boosts engagement.
One socket per class
Drive every dashboard with a single multiplexed stream of participants.
Multi-tenant by design
Isolated data, API keys, and provider-level branding baked in.
BLE + mobile included
Standard HR devices work out of the box. No firmware or custom hardware.
Ship live heart-rate features in weeks.
We manage the infrastructure. You ship the experience.
Sync your class schedule
Push classes via REST. We auto-provision sessions, branding, and access tokens.
Participants connect any BLE device
White-label Flutter app joins the class, pairs, and streams continuously.
Your dashboard receives the aggregate
One socket delivers zones, averages, and live participant status.
Integration that feels native.
Drop in a heart-rate layer without reworking your scheduling, billing, or analytics stack.
Fast integration
Integrate in days with strict schemas, predictable event types, and versioned contracts.
Actionable metrics
Zones, averages, max values, and effort points to power live coaching.
Own the brand
Provider branding, runtime theming, and optional app flavors.
Real-time at scale
Separated ingress and egress, backed by Redis and time-series storage.
Sample stream event
Every message maps cleanly to dashboards, leaderboards, and heat maps.
