Havent had a chance to test the newest release under outdoor lighting, but continues to be an amazing little feat of image analysis that accurately detects pulse rate and breath rate.
Modest disclaimer: I work for Philips, but in a totally unrelated capacity.
Update May 2015: still works as well as ever - not sure what prompted this latest release after a long quiet period. But if you guys are listening, heres a feature request: get the app measurement history integrated into Apples HealthKit! Centralized health data would be a good feature.
