A good thermometer app will help you easily measure your body and room temperature. In the pandemic world, many places require that we measure our own temperatures before entering the premises, and ending up without one upon arrival, especially when one is not provided, can present a challenge.
For that reason, it is especially useful to carry a thermometer with us all the time. However, no reasonable person would do something like that with the actual apparatus.
Luckily, with the evolution of technology, the convenience of a thermometer can now be in our pocket or purse anytime in the form of a mobile app. Check this list for all the things replaced by your smartphone so far.
While all thermometer apps ultimately perform the same basic function, i.e. measure a person’s temperature in either Fahrenheit or Celsius, some have additional features users might find useful. All will display in slightly varying ways, making some more appealing than others to a user’s preference.
Of course, a thermometer app will not be as precise as an actual thermometer due to obvious limitations, but many apps come very close to being entirely reliable.
We have compiled a list of the top best 15 thermometer apps for the iOS and Android platforms for you, so you are never caught without a thermometer when you need it again.

9. Thermometer & Hygrometer
Download: Thermometer & Hygrometer for Android | iOS (Free)
If you are looking for an app that measures the ambient temperature, as well as humidity levels and wind speed, then Thermometer & Hygrometer is the app you want.
The app allows you to get the temperature levels of your local area as well as the percentage levels of humidity in both Fahrenheit and Celcius readouts, with the ability to toggle between the two.

It is capable of measuring ambient room temperature, informing you of outside temps based on your geographical location from indoors, and delivering a lot of information including altitude, humidity, wind, speed, as well as the geographical longitude and latitude.
13. Thermometer
Download: Thermometer for Android | iOS (Free)
Thermometer is a no-nonsense app, but it is efficient at what it does. It is very lightweight, taking up only 2MB of memory, but its unique characteristic is that it can read the indoor temperature while being offline.
