Because precious measurement is crucial for the StressLocator app and since we know that price is important for our customers, it was decided to introduce a ear sensor, a cheaper alternative to our oximeter.

This device is not wireless and the data aren’t so precious, but it enables you to keep both hands free during the measurement and the data are still  much better than those measured via camera-lens. It’s decent enough to fulfill the needs of the app and, not on the last place, cheaper.
