Kinsa Smart Stick

The Kinsa Smart Stick is a simple, digital thermometer that plugs into your smartphone's headphone jack (or via an adapter) to sync with the Kinsa app. It is an affordable way to get the benefits of Kinsa's health-tracking ecosystem without the cost of a wireless ear thermometer. It provides accurate oral, rectal, or underarm readings and automatically logs them in the app, giving you a clear picture of your family's health over time.

It is a great, low-cost solution for parents who want to keep detailed records of their children's fevers.
