Heart Rate
Intelligence

Tachie connects seamlessly with Polar armbands and straps to deliver continuous, real-time heart rate streaming at 1Hz frequency. Unlike typical fitness trackers that sample intermittently, Tachie provides reliable data flow when you need it most — during symptom flares, orthostatic intolerance, or daily activity monitoring.
