Clinical-Grade Intelligence. Anywhere.
QStat was purpose-built to overcome the limitations of consumer-grade wearables in mission-critical environments: no raw data access, motion artifacts degrading measurement quality, vendor lock-in, and unreliable connectivity in difficult RF conditions.
With 50+ configurable onboard sensors, patented Motion Artifact Removal, multi-modal communications, and hub capability for external BLE devices, QStat delivers continuous biometric intelligence for clinical, industrial, and operational use cases.
