The Kinsa Smart Thermometer is a smartphone connected digital thermometer that is compatible with a variety of iOS and Android devices (see compatibility info). The name “Kinsa” comes from the words Kinder, meaning child, and Kin, meaning family. The thermometer is thin and flexible for comfort and plugs into the headphone jack of the mobile device. As the temperature is being recorded, bubbles float around on the display as a means of keeping the child occupied and calm. The Kinsa isn’t just for kids though, it can be used to track your entire family’s temperature readings and illness history. They plan to add features to the app that will be able to tap into local health data to let you know if certain illnesses are going around in your area. The Kinsa Smart Thermometer is priced at $24.99 from Kinsa.
