Clear Speaker - Water Eject is a utility application designed for iPhone users who want to maintain and enhance their device's speaker performance. The app offers features to remove water and dust from speakers by playing special low-frequency tunes, effectively shaking out unwanted particles. Additionally, users can measure sound loudness using the built-in Sound Level Meter, which provides dB level readings to ensure safe listening experiences.

Moreover, Clear Speaker includes a Camera mode to capture moments with sound data stamped on photos, allowing users to document loud events. The Frequency Generator feature enables users to manually clean their speakers by selecting specific frequencies, while the Speakers Test function allows for before-and-after comparisons of speaker performance. Clear Speaker is available for free, with options for subscription plans that provide unlimited access to all features.
