About this app

Temp Master

This app is exclusively compatible with the following Thermal Master devices: P2 / P2 Pro / P1 / P3 / P4.
Note: This version does not support Android 10. If your device is running Android 10, please visit our official website to download the compatible version. (www.thermalmaster.com.)

Thermal Master offers two main series of thermal imaging devices—Temp Master (traditional smartphone thermal cameras) and Thermal Master (thermal monoculars)—covering a wide range of use cases from home temperature monitoring and industrial inspections to long-range (up to 1500 meters) outdoor night vision.

What's new in this version:

Resolved compatibility issues with the X³ super-resolution algorithm on some models. Now fully supports enhanced infrared resolution of 512×384.

P2 now supports high-accuracy temperature detection within ±2.7℉ (±1.5℃). With an upgraded IQ+ precision algorithm, temperature readings for HVAC systems, electrical circuits, PCB diagnostics, and automotive inspections are now even more reliable.

The P2 pioneered ultra-low power consumption in thermal imaging—just 0.3W. We've further optimized the algorithm, battery life can now reach 5–7 hours or more.

Upgraded professional data analysis software: view, save, and export images and temperature data even offline.

Enhanced the Razor X image algorithm, reducing background noise by approximately 20% and achieving a frame rate of 25Hz, ensuring smooth performance even during fast movements.

All Thermal Master devices now support up to 15x digital zoom for pinpoint accuracy when locating faults.

Regarding the system permission prompt when saving images for the first time: this is a standard Android security message shown for all infrared camera apps. We’ve confirmed this with Google. Please feel free to proceed with confidence.

As a global leader in smartphone thermal imaging, Thermal Master is committed to creating smarter and sharper thermal cameras. We hold the largest number of smartphone thermal imaging patents worldwide and offer lifetime free software updates for all products.

Ratings and reviews

Perfect app for my P2 Pro camera! It drains less battery than the default app, plus it offers X3 temporal upsampling which looks better, at the cost of extra battery drain. But why does the app not save the images in the orientation that they were captured? The app clearly knows the orientation of the phone because the text rotates with the phone. The images should be saved in that same orientation. It is very annoying to have to manually fix the rotation of 50 images or videos after the fact.

The app works well, and there are a great range of features and settings. You can set ambient temperature and emissivity values as required, however, my only frustration with this is that you have to create custom profiles to set these values. You cannot change the values of the default profile. You have to exit out of the camera to change profile. It would be much better if you could select these values while the camera is active, as it would greatly help when working with a range of materials.

The app worked great for me. I'm on Android 15. It did a firmware update on my new P1 and everything started up quickly. I used it for about 20min solid without issues. I was able to easily switch from C to F. The resolution of the P1 was better than I was expecting and I was easily able to see missing insulation and air leaks through the walls. I'm not sure why this app has such bad reviews. It worked perfectly fine for me.
