IRSignalTester
Test infrared remotes & LEDs
Free · Designed for iPad
IR Signal Tester is a simple utility for testing infrared (IR) signals using your phone’s camera.
Check if a remote control is working, compare signal strength between remotes, or detect infrared light from IR LEDs — all in real time.
No ads, no fear-based claims, just a practical tool that works.

IR Signal Tester makes this visible and measurable.

Test TV, AC, and media remotes
Check if a remote is weak or failing
Compare signal strength between remotes
Detect infrared light sources and IR LEDs
