Quick answer: A plug-in thermal camera turns your iPhone into a pro-grade thermal imager — find drafts, missing insulation, hidden water leaks, overheating electronics, and more. Get a high-resolution thermal cam for serious pros, a mid-range model for home repair, or a compact pocket cam for everyday DIY. Resolution, temperature range, and your iPhone's connector (USB-C/Lightning) are what matter.

Pro tip — match the connector to your iPhone (USB-C vs Lightning) and pick resolution for your use.
Plug-in thermals come in USB-C and Lightning variants — buy the right one for your iPhone. Higher thermal resolution costs more but lets you spot smaller issues from farther away; for home use, mid-range is plenty. Use against the wall in cold weather to find missing insulation, behind switch plates for hot wiring, and under sinks for slow leaks.
