BreatheBand

Millions of people with mild bronchitis and other respiratory conditions struggle to figure out why their breathing suddenly tightens. Temperature spikes, high VOCs, a brisk walk at the wrong time of day—any of these triggers can turn a routine errand into a gasping episode, yet commercial wearables stop at heart-rate graphs or demand premium prices.

BreatheBand fills that gap.

A 24-g, silicone-soft wristband pairs a medical-grade SpO₂/PPG sensor with environmental, motion and GPS modules to log what’s happening inside your body and what’s happening around you—then correlates the two in real time.
