There are plenty of decent thermometers available on the market. Not all of them are kid-friendly. Most of them are not compatible with smartphones either. Tympani happens to be a smart in-ear thermometer that works with your iOS or Android device to measure body temperature. The companion app lets you maintain a journal to track historical data and share results with your doctor.
Tympani gives you a new reading in a few seconds. It uses the standard 3.5mm headphone jack to work. More information is available on Indiegogo.
