J-Dawgs Speaker Rescue™

What it is

Speaker Rescue is a small web app you open on your phone — no download, no install, no account. It plays calibrated low-frequency tone sweeps (the ~165 Hz class that speaker-cleaner apps use) in timed cycles. The sound waves push air through the speaker grille, which can help eject the surface water and dust that make a speaker sound muffled and quiet.

Then — the part the clone apps skip — it checks its own work. A built-in sound check plays a test sweep before and after, and can measure the recording back through your microphone, so you get a real comparison instead of a spinning "cleaning" animation that proves nothing.

When you buy it, you also get it as a single HTML file you can keep and run yourself. One payment of $2.99. Yours forever.

What it does

• Water Eject — timed sweep cycles in the ~165 Hz class, with a live frequency readout, a real progress countdown, an instant Stop button, and on-screen positioning guidance (speaker facing down, grille clear)
• Dust mode — alternating low tones, plus vibration where your browser supports it. The app detects support and tells you the truth — it never pretends to vibrate on a browser that can't
• Before/after Sound Check — plays a short test sweep; if you tap Record and allow the microphone, it measures the actual recorded sound and shows the comparison. Labeled in the app as indicative, not a lab measurement
• "When this can't help" screen — if your speaker is torn, blown, or still muffled after two cycles, that's hardware, not a tone problem. The app says so plainly instead of selling you hope
• Safety first — a plain volume and hearing warning before the first run: these tones are loud at full volume, keep the phone away from ears (yours and your pets'), never run a cycle with earbuds in
• Runs anywhere — in the browser on your phone, works fully offline after it loads, and as a single downloadable HTML file that's yours to keep. The only permission it ever asks for is the microphone, and only if you choose the recorded sound check

The honest limits — printed here and in the app

• Sound waves can move surface water and dust out of a grille. They cannot repair internal water damage or a blown or torn speaker, and this app never claims otherwise.
• The tones play through your phone's own speaker at your phone's own volume — a web app can't make the hardware louder than it is, and how audible the sweep is varies by device.
• Vibration depends on your browser: Android Chrome supports it, iOS Safari does not. The app checks and tells you which you have.
• The microphone sound check is an indicator, not a lab measurement — room noise, mic placement, and distance all move the reading.
• No result is guaranteed. The honest claim is "can help eject" — never "will fix your speaker."
