We’ve included all types in our list based on our years of research and testing thermometers.

Stores info for eight users

 The Withings Thermo is a smart thermometer that takes readings via the temporal artery located at your temple. It’s non-invasive and can be used quietly while a loved one is asleep and will store up to eight different users' information.

How to choose the best digital thermometer for you 

There are different types of thermometers, including ear thermometers, multiuse ones that can be placed in the ear, under the tongue or arms, or inserted rectally, and forehead or temporal thermometers. Choosing the best digital thermometer for you is a matter of who will be using it, whether they are fine with more invasive thermometers or would prefer a non-contact thermometer, and whether you would prefer smart features too. 

Ear thermometers are not suitable for use on newborns as their ear canals are too small, but they are suitable for older children and adults. Most doctors use this type of digital thermometer, and some commercially available devices come with hygienic disposable lens caps. 

Forehead thermometers are newer, and some health practitioners argue over whether they are any closer to the ‘real’ temperature of your body than rectal thermometers. Some parents also worry about how accurate these types of digital thermometers are. 

If you want to see a clear temperature history, choose a smart thermometer with an in-app data display or a digital thermometer that is capable of recording the last several temperature readings.
