We built SWEL Health because of a massive gap in modern health tech.
Today’s wearables are incredible sensing devices. They capture your sleep stages, your steps, and hundreds of thousands of heartbeats a week. But most athletes hit the same frustrating wall: beautiful charts, but no real answers.
What does a readiness score of 40 actually mean for your session today? Is your Acute:Chronic Workload Ratio putting you at risk of a tissue injury? Why did today’s workout feel so terrible when your watch said you were recovered?
The Problem We Solve
You have a watch that tracks your runs, and a physical therapist or coach who tries to manage your load. They rarely have access to the same context. SWEL is the bridge. We sit on top of your existing devices and transform raw telemetry into professional-grade insights.
Built in South Africa by Immersive Authority, SWEL operates on one core belief: The data your watch collects is only as valuable as the intelligence applied to it.
Our Core Engines:
Advanced Load Modeling: We track your Fitness (CTL), Fatigue (ATL), and Form (TSB) to perfectly time your race-day peaks and prevent overtraining.
Environmental Normalization: We adjust your performance metrics based on real, persisted weather data—so you aren’t penalized for a slow pace on a 35°C day.
AI Fusion Insights: A personalized daily briefing that cross-references your sleep architecture, your upcoming calendar events, and your historical plateaus.
SWEL Intelligence (For Professionals): An exception-based triage board that allows your biokineticist, sports physician, physiotherapist or coach to monitor your mechanical load and systemic recovery in real-time, using natural language rules.
We don’t just track you. We help you understand yourself.
