getting your temperature checked little boy

Taking your temperature used to be just when you or a family member felt a little unwell or when you visited your doctor’s office. These days, taking your temperature is routine at home and when you visit almost any place of business or commerce.

Given that we live in the age of technology, it seems natural to turn to our mobile devices to see if they can check our temperature or assist in checking our temperature.

Although iPhones and Android phones don’t natively have this capability (at least not yet), you can get a smart thermometer.

These smart thermometers go way beyond just reading temperatures by offering advanced features like apps, tracking temperature history, fever indicators, and more!

So let’s look at the best of the bunch, so you and your family stay healthy!

What do smart thermometers offer? Withings smart thermometer man using with iPhone

Smart thermometers work with apps on your iPhone or Android devices, providing near-instant readings that you can use to monitor the temperature and health of all of your family.

Some smart thermometer apps even have reminders for taking medications and can send the data you have collected to a medical professional. 

A smart thermometer is essential during the times like the flu, especially the coronavirus pandemic, but it also has other important uses.

As well as monitoring your body’s temperature and indicating a fever (a temperature above 100.4 °F /38 °C in adults, according to the Centers for Disease Control and Prevention), a smart thermometer can track changes in your body when you’re fighting an infection or help to track ovulation cycles in women.

So which are the best smart thermometers for you and your family?

Well, it depends on which features appeal most to you, who uses the thermometer, and the main purpose for measuring body temperature. 

Many factors may influence your thermometer purchase, such as:

  • The type of thermometer technology you prefer (infra-red non-contact types versus contact to skin)
  • How accurate do you need the thermometer to be
  • The speed of reading that you require.

For smart thermometers, the app experience matters!

The app’s features should also influence your choice of a smart thermometer.

Look at the app’s description and user reviews first.

Think about what app features matter most to you, such as a fever alert (useful for kids and toddlers), the ability to record data, or if you want to connect to other health apps such as Apple Health, Google Fit, or Samsung Health. 

Listed here are the best 10 smart thermometers for iPhone and Android users split into three categories (family, infant, and fertility), and we describe each smart thermometer’s main features.
