Touchless Monitor
Pretty good app. For the front facing camera to get a good reading, set your device screen to its maximum brightness. I want to try the rear facing camera (so I could monitor someone else) but I have to pay to unlock that and other features.
Measuring the Breath Rate is also a nice addition of this app. Having this app along with a finger on camera lens heart monitor app is a wise choice in my book.
