开发者在美国 App Store 的完整简介（英文原文）。

Water in your speaker? Start a cycle and let a low-frequency sweep do the work. Speaker Cleaner plays a 140-480 Hz sweep designed to vibrate the speaker membrane so trapped water can move out of the grille. It may help clear trapped water and loosen dust. It is not a repair tool and cannot undo water damage. FOUR TOOLS IN ONE Water Eject and Dust Mode A 30-second sweep with a live progress ring, the current frequency on screen and haptics that follow the sweep. Turn the volume up and hold the phone speaker-down. Switch to Dust for pulsed 200-2000 Hz bursts instead. Dust needs acceleration rather than displacement, so the band moves up and the attack of each burst does the work. It may help loosen dust and lint sitting in the grille; brush the grille afterwards. Sound Level Meter Live approximate decibel readings with min, average and max plus a 60-second rolling graph. Readings use a real A-weighting filter, but phone microphones have no SPL calibration, so every number is an approximation - useful for comparison, not for measurement. Tone Generator 20 Hz to 20 kHz, sine, square or triangle. Hold a single frequency or sweep a range. Band-limited waveforms, no clicks or pops. Speaker Test Check the left channel, the right channel and stereo separately, then listen through a full sweep to hear where a speaker rattles or drops out. WHY IT IS BUILT THIS WAY - The sweep frequency, shape and length are tuned and verified on real hardware. - Amplitude fades in and out over 30 ms so nothing pops. - Nothing is recorded. Microphone audio is processed on device and never leaves it. Free: one cleaning cycle per day, water or dust, sine tones from 100 to 2000 Hz and live meter readings. Pro removes the daily limit and unlocks every waveform, the full 20 Hz-20 kHz range and meter history.
