SPYDR WEB app for iPhone and iPad

SPYDR (Standalone Performance Yielding Deliberate Risk) by Spotlight Labs is a self-contained solution for high-fidelity biomonitoring of pilots, aircrew and passengers of air and spacecraft.
The device uses low-power optical technology to noninvasively monitor several important physiological indicators including pulse rate and blood oxygen saturation.
SPYDR also has a built-in warning system, capable of alerting the user to impending hypoxic conditions. Finally, all data are recorded for download and analysis after each use.
