IRSignalTester

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.

What the app does Most infrared remotes and IR LEDs emit light that phone cameras can detect — even though your eyes can’t. IR Signal Tester makes this visible and measurable. Use it to: 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

Features Live IR Detection Real-time camera view

Clear “IR detected” indicator

Signal strength meter (weak → strong)

Remote Control Test Guided 3-second test

Signal health results: Good, Weak, Intermittent, or No Signal

Helpful explanations for each result

Compare Remotes (Pro) Test two remotes side by side

Compare signal strength and stability

Quickly see which remote performs better

Clean & Private Works completely offline

No accounts, no tracking

Camera access only, used solely for IR detection

Who it’s for Anyone troubleshooting a TV or AC remote

Technicians and installers

DIYers and electronics hobbyists

Anyone who wants a simple way to check infrared signals

Important note IR Signal Tester detects infrared light signals, not hidden cameras or surveillance devices. Results depend on camera hardware and lighting conditions.
