Clear Sound: Speaker Cleaner

Clear Sound: Speaker Cleaner helps diagnose and improve muffled phone speakers by generating controlled vibrations from 0 to 20,000 Hz to clean and test your speakers, potentially removing water residue and boosting sound quality.

Use the manual frequency generator on the app to enter frequencies, follow the on-screen usage note (keep your phone face down), and review available subscriptions (monthly, yearly, lifetime). Terms of Use and Privacy Policy links are provided.
