I had a chance to try out the flir one for a day. Pretty sweet but not perfect. It has a number of color scales prominently featured in the iPhone UI. Grayscale might match lumosity. I used "contrast" to quickly identify hot / cold parts of my house, then "spot meter" to measure the actual temp. Found out part of my attic is not insulated. That's money going out through the roof.
