What exactly gets embedded?
A compact version of the same tool used on this site: a Web Audio sweep generated inside your reader's browser, with mode, duration, and device controls plus the built-in safety notice. No audio files are downloaded and no microphone permission is requested.
You choose which mode your readers land on. Water Eject plays a 165-250 Hz sweep for trapped moisture, Dust Cleaner runs a wider 300-700 Hz sweep for muffled sound, and Speaker Test alternates left and right tones for audio troubleshooting. Pick whichever matches the article it lives in.
Is it really free, and what is the catch?
It is free for any honest editorial or commercial use, including repair shop sites, and it stays free. There is no metering, no API key, and no upsell, because the widget exists to be useful and to be credited where it is used.
The only conditions are the obvious ones: keep the small attribution link visible, do not present the tool as your own product, and do not wrap it in claims the tool itself would not make, such as guaranteed repair of water damage. If a page needs a different size or behaviour, ask and it will usually be accommodated.
Does it slow my page down?
The iframe is set to load lazily, so it costs nothing until a reader scrolls near it. The widget itself is a small static page with no third-party scripts, no fonts to fetch, and no tracking pixels, so it is far lighter than a typical embedded video or social card.
Because it is sandboxed in an iframe, it also cannot interfere with your page's layout, styles, or analytics. If you ever remove it, deleting the snippet is the entire uninstall process.
Who is already the right fit for this?
Phone repair guides and water-damage first-aid articles are the obvious homes, since the reader arrives with the exact problem the tool addresses. Repair shops use it as a goodwill step: let the customer try the free fix, and the ones who still need help arrive knowing the problem is real.
It also fits tech blogs covering rainy-season phone care, campus and workplace IT knowledge bases, phone case and accessory brands with care content, and travel or watersports sites where wet electronics are a predictable reader problem.
