Collecting health data with Biostrap

Using a clinical-grade photoplethysmography (PPG) sensor for a month

Nov. 15, 2017 -

Most wearables (smartwatches, fitness trackers, etc.) use very basic sensors to capture heart rate. Their signal is binary: just counting beats. Biostrap is different, instead of just checking pulses, it captures a high-fidelity PPG waveform. These waveforms are the same kind that doctors use, making me wonder what I could learn from them!
