The Buyers Guide To Smart Thermometers

In this section, we’re going to look through some features that make a smart thermometer worth the purchase. Here are some of the things I’d look out for:

Reading Method

This is an important thing to think about, especially if you don't want the thermometer up the backside. There are a few methods that can be used, and some of them aren't for everyone. You have the following methods available rectum, forehead, and ear.

Temperature Range

All thermometers will have a temperature range high enough to pick up a fever, but what if you want to use the thermometer for other things. Checking out what range the thermometer can reach safely will avoid you breaking or damaging the calibration.

Connection Type

Now it's time to think about how the thermometer connects to the App. This can be achieved in several ways, including Bluetooth, WiFi, or a wired connection. My personal favorite is always WiFi; it has a far superior range to Bluetooth.

Pregnancy Tracking

Thermometers aren't just for finding out if you're ill. They can also be used to find out which days are best for you to get pregnant or avoid getting pregnant. They can also help you track your periods, giving you a better idea of when it's coming.

Reading Time

Ít's one of the biggest downfalls when it comes to the original thermometer. Gone are the days of waiting around for reading. Smart thermometers today allow you to get temperature readings quickly, and in most cases, it's under 8 seconds; much better than a few minutes!


Some smart thermometers will work in conjunction with an App, but why is this important. Well, it lets you keep track of multiple readings, or it will send you a notification to your phone if anything spikes. You can also keep track of any medications you've taken to kill the fever.


It's probably one of the quickest and most efficient ways of taking a temperature reading. It uses infrared rays to determine your temperature readings. The best thing about it is you don't have to sterilize it after each use.

Memory Recall

A smart thermometer can recall some of your past readings; this helps you to track any changes that need to be looked at. On average smart thermometers can give up to 35 previous readings, which you can access at any time.

The thermometer is highly accurate, and readings typically take a minute or two. Which is a lot quicker when you compare it to basal thermometers.

#4 – Easy@Home Smart Basal Thermometer

This smart basal comes in two colors, Blue or Purple, and can be used to track your temperature as you wake up in the morning. 

By monitoring your morning temperature on the App, it will chart your BBT (Basal Body Temperature) and make predictions on your fertility window using their advanced algorithm.

The App is free to download, but you must enter your BBT reading manually; unfortunately, the thermometer doesn’t have a Bluetooth connection. 

The App will manage everything for you, so you don’t have to worry about a thing, it will even tell you if it thinks you’re pregnant.

The thermometer comes with a large backlit screen, so it’s easy to see your readings even in the dark, and it will also recall your previous 30 readings. 

The reading takes 90 seconds, which is a little bit longer than most, and once the test is completed, a soft alarm sound will be heard.

After a long search looking for a replacement BBT thermometer, they had decided on this one. They really liked the backlit screen; it made it easy to use and see your readings on a dark morning. It took around 90 seconds to get a reading, which was the average time for a basal thermometer.

For another customer, this was their first BBT thermometer, and so far, they were very impressed with its quality. They loved how soft it was; it made it very comfortable. They also felt the light turning off while waiting for the temperature reading was a nice touch.

Final Verdict

The basal thermometer worked well and provided accurate readings, and the soft tip made it feels comfortable in the mouth. Another nice touch was the backlit screen; it makes it super easy to get a reading; the light would even turn off while it was taking a reading.

The App that it works with was fantastic; it can accurately predict your ovulation period as well as letting you know when you’re pregnant. The biggest downfall was having to enter the readings yourself; this was down to the lack of WiFi or Bluetooth technology.

What We Liked

  • Comes with batteries
  • Bright display

Another customer loved being able to monitor their daughter’s temperature without having to wake them up when they were ill. They did have a few troubles when trying to set everything up, but in the end, they found out they were trying to connect to the wrong device.

Final Verdict

The smart thermometer worked well and provided accurate temperature readings you could trust. One of the best things about this thermometer is the ability to leave it on your loved ones and check the temperature remotely; this stops you from having to wake them up.

The Bluetooth was strong enough to reach most of the house, but this depends on the size of your home. Hooking the device up was easy, but I suggest you read the instructions to avoid any confusion. The biggest problem was how fragile the thermometer felt.
