Phone Speaker Tester

Phone Speaker Tester is the complete toolkit to test, diagnose, and clean your phone's speakers and microphone — all in one lightweight app.

Whether your speaker sounds muffled after getting wet, you want to check if both stereo channels work, or you just want to verify your audio hardware is healthy, Phone Speaker Tester gives you professional-grade audio tools in a simple, beautiful interface.

▶ TONE GENERATOR
Play precise test tones from 20 Hz all the way up to 22 kHz. Choose between sine, square, and triangle waveforms, fine-tune the exact frequency, and adjust the output level. Perfect for checking speaker response, finding rattles and buzzes, or testing your hearing range.

▶ STEREO BALANCE TEST
Instantly check your left and right speakers. Pan the sound smoothly across the stereo field or snap hard to the left, right, or center to confirm each channel is working correctly. Great for testing earphones, Bluetooth speakers, and built-in phone speakers.

▶ LIVE SPECTRUM ANALYZER
Turn your microphone into a real-time frequency analyzer. Watch a live spectrum of the sound around you, see the dominant peak frequency and volume level, and visually inspect how your speakers and room respond across the full audio range.

▶ SPEAKER CLEANER (WATER EJECT)
Got water in your speaker? Run the sonic cleaning routine — a carefully designed sequence of low-frequency sound waves and vibrations that help push trapped water droplets out of your speaker grille. Ideal after rain, sweat, or an accidental splash.
