The Wishbone is an infrared thermometer, which means that you don't have to stick it under your tongue or anyplace else unpleasant. In fact, it requires no physical contact at all; just hold it a few centimeters from someone's forehead to get a reading. While IR thermometers are nothing new--and studies consider them about as accurate as traditional thermometers--the Wishbone's integration with a smartphone app, which lets you log temperature records over time, could prove helpful for those who want to track health data as well as easily share it with health providers.
