What it does

Built around one camera

Every screen is aimed at the same job: getting a clean read on temperature, fast, and keeping what you capture organized.

Region measurement: a resizable box overlaid on the thermal image showing average, minimum, and maximum temperature
Region measurement

Drag a box, not a point

An alternative to the point spotmeter — resize a box over the frame and read its average, minimum, and maximum instead of one spot value.

Library screen listing saved thermal images and recordings, grouped by date
Library

Everything, grouped by date

Browse saved images, recordings, and time lapses together, filter by date range, multi-select, and delete straight from the grid.

Temperature history dialog showing a rolling chart of spot, max, and min temperature
Temperature history

A rolling chart, not just a number

Spot, max, and min plotted over the last five minutes — styled after desktop thermal tools, with real gridlines and a legend, saveable as a chart file.

Exported thermal image composite with color bar, spotmeter marker, and capture metadata footer
Share & export

Leaves with its context intact

Exports composite the image at 4× with the color bar, spotmeter marker, and gain/emissivity/timestamp baked in — not just a bare frame.

Charts screen listing saved temperature-history charts, grouped by date
Charts

Saved histories, kept separately

Every chart you save gets its own screen — same grouped-by-date, multi-select, filterable browsing as the Library.

Reliability

Reconnects on its own

If a connection drops mid-stream, the app retries the last known address, then falls back to mDNS in case DHCP handed the camera a new one.
