An infrared tester for remotes, IR LEDs, and real-time signal strength.
IR Signal Tester is a practical utility for testing infrared signals with your phone camera. Check whether a TV remote, AC remote, media remote, garage remote, or IR LED is working, compare signal strength, and see infrared light your eyes cannot detect.
The app includes live IR detection, a clear IR detected indicator, signal strength meter, guided 3-second remote tests, health results like Good, Weak, Intermittent, or No Signal, and Pro remote comparison. It works offline with camera access used solely for IR detection.
Important: IR Signal Tester detects infrared light signals, not hidden cameras or surveillance devices. Results depend on camera hardware and lighting conditions.
