*Price typically updated every 24 hours. Current price may be different.

Generation Guard is a family company that prioritizes the needs of your family. Our gold pick, which is the Generation Guard clinical basal thermometer, is a device that is loved by critics and consumers alike, just like many of our gold picks. The device is FDA approved and European CE approved to assure you that the thermometer is clinically accurate. In fact, this thermometer is designed to track your body temperature to 1/100th of a degree in Fahrenheit, which is one of the most accurate readings you can get in a thermometer. The unit is designed with an incredible amount of sensitivity, so it can produce extremely accurate results.

The process of taking your basal body temperature will take between 60 seconds and 120 seconds. When the device has an accurate reading, it will produce a soft beeping sound. This feature allows you to rest your eyes while the reading is in progress, which may be a welcomed few minutes since you are just waking up. This device features a LCD screen that is easy to read, and if you want to use a BBT (basal body temperature) tracking chart app, this thermometer is able to be paired with quite a few of them. Once you know what your basal body temperature is, you can easily clean the thermometer, since it is water proof, and then you can safely store it away in the clear case that is included with the product.

When it comes to the reviews for the Generation Guard basal thermometer, there are quite a few to be found. On Amazon, 82 percent of the 182 reviews posted on the site have received positive four or five star reviews. The general consensus of this device is that it is incredible accurate and easy to read. The only thing that a few customers have mentioned wishing was included on the unit is a backlit LCD screen, which is a convenience of course, but not a required feature.

Here is what one customer had to say about this thermometer: “I’m pretty impressed with the quality of this thermometer. It has been pretty cool to watch my temperature change as I get closer to ovulation. The difference is really pronounced as I took my temperature while I happened to be sick and it read as 100.4 and I took my temperature with a regular ear thermometer and it only read like 97.1 or something like that. It’s super easy to use and works great. I would highly recommend!”

#2.  Easy At Home Digital Oral Basal Thermometer

*Price typically updated every 24 hours. Current price may be different.

Our silver pick is the Easy at Home basal thermometer, which is a digital device that takes your temperature orally. It is designed to be clinically accurate, which means that it records your temperature to the 1/100th of a degree. The device only takes about 120 seconds to acquire your temperature, but the actual amount of time will depend on the temperature of the room as well as your temperature. Once the reading is available for you to see, there will be a soft beep that can be heard three times to let you know that it is complete. If you hear that same beep ten times, that means that you have a fever that is over the normal range, which is above 99.50 Fahrenheit.

The screen that you read the data on is a LCD screen that is backlit blue to make it easier to read, especially in low light areas like your bedroom in the early morning. The screen displays the date and the time that the reading was taken as well as your basal body temperature at that time. One feature that makes this thermometer stand out is the fact that it can recall up to 60 temperature recordings, so if you happen to forget to record a Monday’s data and you remember it on Wednesday, you will still be able to recall what your body temperature was on Monday.

There is a soft wake up alarm included on this thermometer that will gently wake you up at the same time each day. To make recording your temperature each day even easier, the manufacturer has included a BBT chart in the packaging as well as a convenient carry case. When it comes to the reviews of this basal thermometer, 76 percent of the users who reviewed this product on Amazon rated it with four or five stars. Here is one example of a five star testimonial: “I love my thermometer. It stores data for the previous 60 readings, which is extremely helpful especially when taking your temperature in the wee hours of the morning like I do. I have not had any problems with it functioning after over a week of use. I love the light up background and alarm clock function. It takes my temp in just a couple minutes. I can’t imagine taking my temp without this now.”

IProven is the mother’s first choice in care when it comes to their newborns, so it should also be where you turn to conceive.

This model has a soft wake up beep that is designed to wake you up and only you, just like our silver pick. If you are too tired to record the data, then the device will store it for later. As an added bonus, this basal thermometer will turn off automatically after five minutes. When you are awake enough to record the data from the early morning reading, simply press and hold the button on the thermometer for about three seconds to bring the information back up on the LCD screen.

When you purchase this basal thermometer, the manufacturer provides you with a convenient case to carry the device in, a free basal body temperature chart that can be downloaded from their site, and a limited one year warranty to stand behind their product.

It’s high quality for sure; much, much better than many others I have tried. I love that it’s highly sensitive; I have many health issues that affect my fertility and I can’t count on counting days or ovulation tests, but routinely taking my basil body temp is a foolproof way to keep track of my body.”

Pre-purchase considerations

Glass or Digital

There are two types of basal thermometers that you can purchase, which are the digital type or the glass type. Glass thermometers tend to take a bit longer to get an accurate reading, but they are oftentimes more accurate than the digital options. The other issue is that glass thermometers can easily break if they are dropped, but on the other hand, a digital one can have an electronic failure or run out of battery juice. Decide whether speed or accuracy are more important to you, and then choose which type of basal thermometer fits your needs.

Accuracy and Speed

When you are trying to get pregnant, you may be anxious, especially in the morning when you are trying to find out your body temperature. You want a thermometer that is fast and accurate, but taking your temperature for too little of a time can make the reading inaccurate. The device needs to be reading your body temperature for at least 30 seconds, but to assure the results are accurate you want a thermometer that will have your results in about a minute. The reason that a basal thermometer is better for determining your ovulation cycle is that it actually will determine what your body temperature is down to 1/100th of a degree, which is the extreme level of accuracy that is required. This is because when you ovulate, in most situations your temperature only rises by half of a degree to one degree, which may be too small of a difference to notice on a regular thermometer.

Lighting and Sound Options

Since your basal body temperature is taken right when you wake up in the morning, you may be groggy while taking it. This issue is solved by the sound functionality that is included in some basal thermometers. It will make a beeping sound when the results are in to let you know, just in case you start to nod off again. Some devices vibrate instead of beep, which is actually preferred by some individuals, so decide which method, if any you prefer. Also, when you wake up, it may be dark in your bedroom, which makes it hard to see the display on the thermometer to see if today is the day. Some thermometers have a backlit display that will make it easy to read in low light situations.


Since you are going to be just waking up when you take your basal body temperature, it is likely that you will not be able to record the information immediately. To help keep you from forgetting the data, some thermometers record the last temperature that was recorded. There are a few on the market that record a few more than the last temperature, so if you think you will need that reminder of what the reading was, then look for a device that can record it for you.

Memory and App Compatibility

Taking you temperature can be fast and convenient with many of the basal thermometer available, but you still have to record the results in most situations. Since your basal body temperature is taken first thing in the morning, you may not want to rush out of bed to record the results. Some devices do record the last result, but what happens when you wait until later and then completely forget to record the data? Having a basal thermometer that can link up to an application on your cell phone or tablet and simply upload the information takes the step of recording the information out of your hands. If this is a feature that you think calls to you, then see if it is available on the basal thermometer that you are considering purchasing.

Conclusion (Wrapping it up)

Trying to have a baby can be a stressful time, so instead of worrying about when your ovulation is going to happen, you can take the initiative and track your basal body temperature to see when if fluctuates. Hopefully this guide has helped you decide which basal thermometer to purchase, but if not, then take another glace at our pre-purchase considerations to help you find a device to help you track your ovulation. With the help of a basal thermometer, you will be waiting for the arrival of your new born baby in no time.
