Clear Tune - Clean Speaker

Clear Tune is a frequency-based tool designed to help clean a water-damaged phone speaker and boost sound. It uses a sweep from 50 Hz to 30,000 Hz to help eject water. The app provides simple steps: place your phone screen-down, increase the volume, and select the model. If permission prompts appear, enable microphone access in Settings to ensure proper operation.

The app includes an optional auto-renewable subscription (Month, 6 Month, Year) with a free trial. Pricing is listed within the app, and a privacy policy and terms of use are available through the provided links.
