## What is Thermal Viewer?

Thermal Viewer opens and analyzes radiometric thermal images right on your iPhone, iPad, and Mac. No Windows PC, no camera accessory, and no account.

Searching for "FLIR Tools for Mac" or a SmartView alternative? This is the native app you have been missing. FLIR discontinued its Mac software and Fluke's mobile viewer is no longer maintained. Thermal Viewer fills that gap, fully offline.

WORKS WITH
• FLIR radiometric JPEG: E-series, T-series, Cx, FLIR ONE, CAT phones
• Fluke IS2 files
• Radiometric TIFF (ResearchIR, Vue / Duo Pro R)
• InfiRay / P2 Pro thermal JPEG
• DJI thermal JPEG (image and capture parameters)
• Plain thermal JPEGs

EVERY PIXEL IS A TEMPERATURE
Tap anywhere to read the exact temperature. Add spot, box, ellipse and line measurements with min / avg / max, and Delta-T between any two of them.

PROFESSIONAL ANALYSIS
• 8 color palettes plus your camera's own palette
• Level/span with histogram, isotherms, automatic hot and cold markers
• Live re-analysis: change emissivity, reflected temperature and distance, and temperatures recompute instantly
• Visible-light blend, picture-in-picture, and MSX-style edge overlay
• °C / °F / K
• Full camera, lens, GPS and parameter inspector

EXPORT & BATCH
• Export the full temperature matrix to CSV
• Export rendered images (PNG) and reproducible analysis settings (JSON)
• Hotspot Triage: scan a whole folder and flag every image above your threshold
• Batch export

PRIVATE BY DESIGN
Everything runs on your device. Your images never leave your phone: no cloud, no account, no tracking.

Thermal Viewer is an independent app and is not affiliated with, endorsed by, or sponsored by FLIR, Teledyne, Fluke, DJI, or InfiRay. Brand names are used only to indicate supported file formats.
