Tepna
local-first physiological analyzers (oximetry, HRV, CGM, ECG)
What is Tepna?
Tepna is an open-source suite of browser-based analyzers for consumer physiology sensors such as ring oximeters, chest straps, armbands, CGMs and CPAP machines. Each analyzer reads one raw signal, derives its metrics with an evidence grade on every number, and a fusion layer reads across signals; nothing is uploaded, and the build fails if any page reaches for the network.
