Classic thermometers will get the job done, but if you want to take temperature reading to the next level, including keeping records and instant fever indicators, then you'll want a smart thermometer. These are the best options for you, your kids, and anybody else who wants to be healthy in your home.

Top pick

iProven DMT-489

Our top pick is the same as the Wirecutter's because it works as both an in-ear and an infrared forehead thermometer, making it great for both kids and adults. If you want to take your sleeping child's temperature without waking them, the forehead option is gold. Other than that, you can recall the last 20 readings right on the device, calibrate it, use color indication for temperature, and you can switch between Fahrenheit and Celsius.
