Thermlapse

A thermal time-lapse where each frame stores the actual per-pixel temperature data (radiometric values), not just a colorized RGB image. The original temperatures are preserved across the entire sequence so you can analyze, scale, or re-render the data later — for example, isolating a specific temperature band weeks after capture.

FLIR ONE Classic (USB-C tethered to the phone), FLIR ONE Edge (Wi-Fi), and FLIR ONE Edge Pro (Wi-Fi). All three deliver a live radiometric stream that Thermlapse records as a time-lapse with full per-pixel temperature data.

FLIR's first-party iOS app does live preview and single-frame radiometric capture, but it does not record radiometric time-lapses — you can take a video, but the per-pixel temperature data isn't preserved across the sequence. Thermlapse is built specifically for that workflow: configurable interval (1 fpm to 1 fps), automated total-duration captures, and the full radiometric stream stored frame-by-frame.

From one frame per minute up to one frame per second, configurable. Slower intervals are useful for long-duration thermal trends (overnight building cooldown, an HVAC cycle, an electrical panel under load); faster intervals are useful for shorter events where you still want measurable temperatures rather than a video.

Building envelope inspectors documenting thermal bridges over time; electrical inspectors monitoring panels under load; thermal researchers running controlled experiments where the per-pixel temperature data is the deliverable; and FLIR ONE owners who want a workflow the manufacturer's own app doesn't ship.
