FLIR Tools for Mac is gone. Here's what Mac inspectors use instead.

Most inspectors used a small part of FLIR Tools, and used it constantly:

• Import a folder from the camera and browse it as thumbnails.
• Read the temperature anywhere in the image, and add spots, boxes and lines.
• Fix the emissivity, reflected temperature or distance set wrongly in the field.
• Change the palette and the temperature span so the defect stands out.
• Put the thermal and visual images into a report.

Those five jobs cover the bulk of residential, electrical and roofing work. They are the list to check any replacement against.

FLIR Thermal Studio is the official route and the most complete one for FLIR files. On a Mac it means a virtual machine (Parallels or similar), a Windows licence, and the Thermal Studio subscription. It works, but it is the most expensive option, and it still reads only FLIR files, so a DJI drone or an InfiRay-based camera in the team needs another app.

HeatDeck reads FLIR radiometric JPEGs natively on macOS and covers the FLIR Tools list above: thumbnails, live temperature, spot, box and line tools with min, max and average, object parameter correction, palette and span locked across a batch, and a one-click PDF report with your logo. It reads InfiRay / Topdon .irg files too, and DJI R-JPEG, HIKMICRO and Fluke .is2 are coming soon.

It costs $19 a month or $149 a year for Pro, and the free plan opens 10 images a day, enough to check whether it reads your camera's files before you pay anything.

Your old FLIR JPEGs keep their radiometric data whatever software you used to view them, so an archive from FLIR Tools opens as-is. Measurements you drew in FLIR Tools are stored as overlays in the file; HeatDeck recomputes temperatures from the raw data, so you can redraw a spot and get the value from the original calibration.
