Top 6 Best Thermometer Apps for Android & iPhone to Measure Body Temperature: Do You Have a Fever?

If you do a quick search on Google Play and the App Store, it won’t take you long to find dozens of thermometer apps for your mobile. But not all are reliable Best Thermometer Apps, far from it.

Of course, not all are equally effective. Some are nothing more than a waste of valuable time to assess your health. To avoid extra headaches, we will teach you how to take your temperature with the following Best Thermometer Apps:

1. Oblumi Tapp, the infrared thermometer

Thermometer app that is combined with an external device connected to the jack input of your mobile to take the temperature. After purchasing the external device, you can download the app and, from there turn your mobile into a thermometer.

It has won many awards for its great effectiveness in recent years, including the First Biotechnology and Health Award 2014, Award for the best Wearable National Congress 2014, and the Best Business Tick Forum project 2015, to name Some.

Oblumi Tapp works based on an infrared sensor that only takes 5 seconds to determine the body temperature. Calculate the dose of the medicine to be applied, save each measurement in a record that can later be shared in clinical history and create several profiles to divide the information among relatives.

You can also use it to measure the temperature of liquids, which is a great help to give the baby a bottle. It is compatible with Android 4.2 and iOS 7.0, it includes a user manual with the purchase, and the app does not take up much space on the devices where it is installed.

2. Smart Thermometer

Its operation is different from the previous option, although it can get you out of a jam in some situations. The app uses the temperature sensors of the mobiles to be able to track the values ​​on the periphery of the device. Therefore, it is only recommended for more current equipment.

Despite this, you can also install it on Android versions 4.0 and higher. The latter cases do not use mobile sensors, but the Internet’s values are based on the mobile’s GPS.

It is not a 100% safe app, but you can use it to complement the values set by other Best Thermometer Apps or make a quick diagnosis before opting to go to the doctor. Its interface maintains a minimalist profile and has its own widget so that you can access the data from the main screen.

3. iThermonitor

Software endorsed by the Food and Drug Administration of North America (FDA) and with a great receptivity of use in some hospitals. Part of its system for analyzing the data was developed with Boston Children’s Hospital’s help, a center affiliated with Harvard Medical School.

This thermometer app is combined with a patch put on the armpit and sends information every 4 seconds via wireless to the devices. Temperature monitoring is constant, making it perfect for chronic patients who are treated at home or whose condition is very unstable.

It has an automatic alert system that is activated when the temperature exceeds normal standards. All data is stored in the cloud so you can have a complete and secure record. You can also combine it with the Health application. Regarding this, it is only compatible with iOS 8.0 or higher devices.

4. Body Temperature Diary History: Fever Thermometer

Body Temperature Diary History helps us record and analyze our body’s temperature (and pulse). Although it is NOT a mobile thermometer as such, it can be useful in episodes of fever or high fever.

One of its strengths is that it does not store your personal health data, only – according to the developer – it is only saved on your own device. Also, it is possible to use the app without an Internet connection, and its design is very user-friendly. Export all your registered data to CSV if you need it.

Free, easy to use, and very useful when it comes to recording our fevers for long periods of time.

5. Fever Tracker

Although the alternatives outlined allow you to store the information locally, you may prefer a more secure backup in an external app. At this point, Fever Tracker can be of great help since it operates in a similar way to a mobile diary where you can put how the evolution of your temperature has been in recent days. A bit of what menstrual calendar applications usually do.

Its interface allows you to create multiple profiles in case several members of your family use it, and you can also share the information through different channels with your GP.

Once you have taken the temperature with an external device (the app does not offer this function), you must enter the values ​​thrown to store the software’s exact date. With this, you will keep an accurate record that also allows you to indicate what medication you have used to counteract the symptom.

6. Fever Control

It is available in 5 languages ​​(Spanish, English, French, Portuguese, and German). With the possibility of setting it in Fahrenheit and Centigrade, it is another alternative to record fever episodes on your mobile. The app is updated frequently, includes evolution charts, and is compatible with Android from 4.3.

Its mode of operation is integrated into its interface with a practical user manual and allows you to create as many profiles as you want to manage the information. Although it is aimed at child patients, it can also be used to store adult records.

You can add the date of each measurement accompanied by a brief description of your condition at that time. You can also put the medicine you take to relieve it and see how effective it is based on the following temperature measurement. You can also set up periodic alerts, so you don’t miss the next measurement.

Do Fever Measurement Apps Really Work? Are They Reliable?

If you’ve started this post believing that apps are 100% infallible, it’s time for us to point out a couple of things.

First of all, remember that no device can perfectly replace a thermometer or any other instrument specifically designed to measure temperature. They can be helpful in obtaining a more or less accurate measurement, but this must be supported by a specialist or by an appropriate instrument.

In the case of the analyzed software that uses these tools in the app (Oblumi Tapp and iThermonitor), you have a higher percentage of certainty than others.

As for the others, it is likely that the results you see on the screen vary circumstantially with respect to the true ones. For this reason, you should never use them as references to determine if you have already overcome a pathology.

In the case of a pandemic like a coronavirus, for example, it can be counterproductive for your health and that of others. In conclusion, and except for the 2 exposed, use these apps with caution and always consult the opinion of a qualified doctor.

Medisana Thermodock: turn your iPhone into a digital thermometer

An alternative to the fever measurement apps seen so far is Medisana’s Thermodock, an accessory that turns iOS devices into a digital thermometer. It is a small device that connects to the iPhone’s charging port (requires an adapter from iPhone 5 on) and that measures the temperature through infrared.

And how does the Thermodock work? It is as simple as placing the phone about 5 centimeters from the forehead and waiting a few seconds to see the result on the screen. If we have a temperature higher than 37.5 ºC, an alert will be sent to the mobile as we have a fever. For any questions about its operation, you can consult its instruction manual.

Also, the device works in conjunction with the VitaDock app, where you can write down your values ​​daily and add comments. We leave you its official link:

Honor Play 4 Pro: the first mobile that measures your fever

If you were wondering if there is a mobile capable of measuring body temperature, you should know that the first phone that can take the fever has recently been presented in the Chinese market: the Honor Play 4 Pro.

To do this, the Chinese company has developed an infrared sensor that works like the one included in digital forehead thermometers. This sensor is located on the back of the mobile and can take body temperature without the need for contact, that is, by placing the device a few centimeters from the person or animal. Its measurement range goes from -20 ºC to 100 ºC.

At the moment, this model is only available in China at a price of €365 (applying the currency exchange), and it is not yet known when it will arrive in Europe and other regions.

How to know if I have a fever without a thermometer

Knowing the previous warning below, we will proceed to describe a series of symptoms that may alert you that your body temperature has exceeded normal values. They are not 100% a guarantee of having a fever, but they can give indications:

  • Dehydration: especially when it is focused on the mouth or skin. You can also make an appearance if you have difficulty urinating or urinate less often than usual.
  • Sweating: When you have a fever, your body activates its natural defense mechanisms to self-regulate its temperature. As you know, sweating is one of the most effective. For this reason, and especially when the fever has reached unsafe limits, sweating is a symptom that will not be lacking.
  • Frequency heart: raising the heart rate is one of the classic symptoms of fever. There is an empirical method to determine what degree of this you have, although it has to be applied with caution. It consists of measuring the heart rate, and every 10 extra beats will represent one more degree of temperature. For the measurement to be accurate, you must know the number of normal heartbeats in your body. The conditions of your body and stress can motivate that the result is not 100% effective.
  • Multitude of conditions: although it naturally varies according to each patient, fever is often accompanied by the following: chills, headache, muscle pain, weakness, lack of appetite, and general malaise.

Keep in mind that the average body temperature is 37 degrees Celsius. This can be higher or lower depending on internal or external factors.

Although we often forget it, a rise above 40 degrees in many cases is fatal. You should not consider this type of episode a game. For greater safety, it is best to contact a specialist or use a conventional thermometer.

Where is it most reliable to take the temperature?

Unanimously, specialists agree that the rectum is the best area to take a temperature. On average, the values ​​of other parts of the body such as the armpits, the mouth, or the groin can vary between 0.3 ºC to 0.8 ºC with respect to those of the anal area.

For this reason, this is the preferred site in cases of extreme urgency or in babies (who are more susceptible to changes in temperature). Here too, less external interference is generated, and results are obtained more quickly (half the time of other parts of the body).

The use of special thermometers and expert analysis is recommended to interpret the results.


We can conclude that fever is a serious condition that must be taken into account depending on the severity in which it can evolve. Using the help of apps and thermometers should only be considered like this: a help. Expert opinion should always prevail to prevent unnecessary fatalities or complications.
