Biostrap band now lets you keep a watchful eye on other people's wellbeing

Biostrap, the fitness tracker that aims to go deeper on biometric insights than most rival devices, is rolling out some new updates, the most interesting of which will let you remotely monitor someone else's health data.

The new feature will let users grant access to someone else who will be able to track their heart rate variability, resting heart rate and SpO2 data. So doctors who want to monitor patients or people keeping an eye on the health of a loved one, will be able to do so from afar.

While many fitness wearables let you connect with friends and loved ones to compare and compete on daily activity data (usually steps) Biostrap's data sharing feature is for keeping a closer eye on someone's physiological wellbeing. That might even be sports coaches monitoring their players.

Biostrap is adding a couple of other new features too, including an update to let users pair a Bluetooth heart rate monitor with the app for workout sessions. "The main motivation for this is that it's known that chest straps are much more accurate vs a wristband heart rate sensor," Biostrap CEO Sameer Sontakey told Wareable.

"It seems counterintuitive to most, but we hone in our strengths. The wristband collects raw PPG for deep biometric data, while we rely on a simple HRM for active HR readouts."

Finally, it's updated the sleep tracking so that user biometric data like HRV and SPo2 are displayed alongside the sleep graphs.

Biostrap delivers insights that are meant to give users a better indication of their overall health. However the device isn't yet FDA approved and the last time we chatted to CEO Sontakey about the device, he made it clear that this is very much a phase-one wearable. The goal is to achieve more mainstream appeal, while still offering deeper biometric insights than its rivals.
