About
Infrared Explorer turns a phone with a FLIR ONE thermal camera into a science instrument for the classroom, the lab and the field.
SEE HEAT
Point the camera at anything and watch temperature become color, live. Switch palettes, lock or free the temperature range, and read the value under the crosshair.
RECORD AND ANALYZE
Capture thermal clips that keep the temperature of every pixel, then play them back with thermometers and analysis tools. Compare a kettle coming to the boil, a running motor, or the wall of your school on a cold morning.
TIME-LAPSE
Leave the camera watching for up to 24 hours: one thermal frame every few seconds or minutes, played back as a film. With a wired FLIR ONE, the recording carries on with the phone locked, and a Live Activity on the lock screen shows its progress.
LEARN WITH REAL DATA
Lessons and a Showcase of experiments from other classrooms give you something to try today. A Video Store of sample recordings works without any camera attached.
MAP THE INVISIBLE
Infrared Street View captures panoramas with their temperatures, geotags them and shares them on a map with other explorers.
GO FURTHER
Sign in to upload recordings to the cloud, join a class, and have an AI model draft a lab report from your own data.
Requires a FLIR ONE thermal camera: FLIR ONE Gen 3, Pro or Pro LT with the connector that matches your iPhone, or a FLIR ONE Edge / Edge Pro over Wi-Fi. Without a camera, the sample recordings and the built-in simulator let you explore every feature.
Infrared Explorer is made by the Institute for Future Intelligence, a nonprofit. It is free, with no ads and no in-app purchases.

What's New in Infrared Explorer
3.0.1
October 8, 2026
• Gallery files now open straight into analysis as a full page, with a filmstrip to move between photos and recordings. • Tap a file's title to rename the experiment. • Upload a recording to the cloud from its More menu; uploads and downloads are faster and more reliable. • New setting: Calibration During Recording holds the camera's shutter for the whole take. • The recording screen's color scale now matches the player's, with the range set on number wheels. • Analysis pages have a ⋮ menu for Home, My Gallery, Settings and Help. • Charts of recordings appear faster, and probe labels no longer flicker during playback. • Many smaller fixes to the camera, player and sharing.
