How To Check Room Or Body Temperature Using An iPhone

Last Updated Dec 16, 2022
Medical supplies and a phone

When we aren’t feeling well, we naturally want to check the room temperature and our body temperature to see if either is affecting us negatively. This can be done by using an iPhone.

You can take your body temperature or the temperature of your room with a quick tap of your phone by downloading a third-party application and using an external thermometer.

There are many different apps available to check room temperature and body temperature. Keep reading to learn which ones are the best and understand how they work.

How to Check Room Temperature with an iPhone

Although an app itself will not read the room’s temperature without a little help from room sensors, you can manage to get the job done with a bit of an investment.

For example, if you buy the Govee thermometer, you can hook it up to an iPhone app from the App Store. 

Once hooked up, follow these instructions to check the temperature:

  1. Open the Govee Home App
  2. Connect the thermometer or sensor
  3. Ask Google or Alexa to tell you the temperature of the room
  4. Alternatively, open the app and read the temp

These steps are similar for all similar smart temperature sensors that use apps on your phone. 

This allows users to select brands and sensors that match their smart home kit.

Best Apps for Checking Room Temperature on iPhones

If you aren’t ready to buy a Govee, or are just curious about your other options, below is a list of some of the best apps for checking your room temperature with an iPhone:

  • Govee Home App
  • Nest Home App
  • Alexa Home App
  • Temp Stick
  • Ambient Weather
  • Sensor Push

All of these apps allow you to buy sensors to adhere to your home so you can measure the temperature from your iPhone at the tap of the screen.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              

How to Check Body Temperature with an iPhone

Similar to the room temperature option, taking your body temperature with an iPhone requires you to buy a thermometer with an app that integrates with your phone.

For example, Kinsa uses the Kinsa App on your iPhone to sync body temperature readings to your phone. To use it, follow these steps:

  • Enable Bluetooth on your iPhone in the settings
  • Open the Kinsa App
  • Tap OK when asked to allow the iPhone to use your Bluetooth
  • Sign up and log in
  • Start taking temperatures for yourself or your family

Each thermometer on the market has a similar setup. So although the iPhone itself cannot take a body temperature, it can sync and store the info when paired with a smart thermometer.

Best Apps for Checking Body Temperature on iPhones

Kinsa is not the only smart thermometer that uses an app to sync to your iPhone. Below is a list of other great alternatives that pair well with an iPhone or Android phone.

  • Kinsa
  • Wellue
  • iHealth
  • Withings
  • Tempdrop
  • Sense-U

These thermometers allow you to use an app to store readings, track changes, and store different family members’ information to make it organized and easy to read.

How Does the iPhone Read Temperatures?

The iPhone reads temperatures through third-party sensors. These sensors send data to the iPhone to inform users about the information they want. 

Temperature sensors can often pick up readings such as

  • Indoor temperature
  • Outdoor temperature
  • Humidity

This is useful when preparing a nursery or preventing a bad hair day. It is also useful when figuring out what to wear. 

How Accurate are iPhone Temperature Readings?

Since an iPhone can’t take the temperature itself and you have to use an external device, how accurate are temperature readings?

iPhone temperature readings are extremely accurate when using a third-party app. The sensors connected to these apps are some of the most advanced technology available.

If you, however, rely on the temperature reading on the iPhone itself, this is not accurate. iPhone temperature sensors do not read air temperature. This is why a sensor is required.

Thermometers to Pair with iPhones

It is important to understand the value and quality of thermometers before choosing them. We have listed some of the best options above, but we provide more detail on their perks below.

Thermometer BrandWhy We Love It
KinsaThis device stores temperatures provides tips to soothe fevers, and provides coupons for popular medicines
WellueMute function, four styles for infants to adults, memory functionality
iHealthNon-contact, memory function, user-friendly app
WithingsLong battery life, non-contact, high precision
TempdropCan track temperature and ovulation, wearable
Sense-UPerfect for infants, tracks sleep, positioning, and temperature, low Bluetooth emission

Each of these thermometers has convenient apps to store and read all your temperature information. 

These apps often go one step further and offer other tracking and advice.


Although the iPhone itself cannot read temperatures on its own, when paired with the right smart device, it becomes a powerful tool for any family to utilize.
