Thermal imaging is a technique used to view the heat bodies present in the dark. Thermal imaging apps are very useful to see through the dark and temperature differences in any location. But one must know that thermal imaging apps do not have the ability to work standalone without a thermal imager.

You need to purchase a thermal imager before using thermal imaging apps in an android or ios mobile. Thermal imaging output is different than what you see from a normal mobile camera. Below is a picture showing how a thermal pic would look like.

Flir Thermal Imaging App:

Flir has two models that work with mobile phones. You can buy the flir one pro ( For iPhone/iOS  and For Android Mobiles ). There is another lower-end model flir one, check it here. Having any of these devices attached to your mobile can get you crystal clear thermal images and you’ll be able to look into the dark without switching on your mobile torch.

There are other notorious thermal imagers for android and ios. They are listed below.

Keep in mind, whatever thermal imaging app you install, without purchasing a separate thermal imager, it won’t work in your mobile phone unless you have a phone like cat60

Thermal Imaging App

The thermal imaging apps act similarly to the thermal imaging camera and they can be used easily with a thermal imager. There are thermal imaging applications developed specifically based on the operating systems. They can be classified into two types: thermal imaging apps for android OS and thermal imaging apps for iOS.

Thermal Imaging Apps For Android OS

Android is the most common mobile OS as of now followed by Apple’s iOS platform. The android OS is effective and it can operate several useful applications at less cost. There are many types of android OS-compatible apps available in the Google play store, the top-rated free android thermal imaging apps are listed below.
