Why choose Beam AI

Three reasons developers switch

Every competitor says "accurate" and "easy." Here's what they won't show you.

99.2%

Heart Rate Accuracy

Peer-reviewed at CVPR 2023

Published MAE on UBFC and MMSE-HR benchmarks. Not vague "highly correlated" claims — actual error margins you can cite in your own publications.

$99

Starting Price / Month

Transparent pricing

Competitors charge $50K+/year with custom enterprise contracts. We start at $99/mo with self-serve signup. Scale to $499/mo for unlimited. No sales calls.

5 min

Integration Time

npm install + 3 lines of code

Import, initialize, monitor. Full SDK documentation, sample apps on GitHub, and a sandbox environment. No hardware dependencies, no vendor lock-in.

Integration

Three lines. That's it.

ViewController.swift

import BeamAI

let monitor = BeamMonitor(apiKey: "your-api-key")

monitor.startMonitoring { vitals in

    print("HR: \(vitals.heartRate) bpm")

    print("Stress: \(vitals.stressIndex)")

    print("HRV: \(vitals.hrv) ms")

}
