Now you can help move trapped liquid and dust out of your phone speaker with Speaker Cleaner - Eject Water. Use clear Hz tones, checks and results to hear what changed. Speaker Cleaner - Eject Water is made for quick speaker care after rain, splashes, pocket dust or muted sound. Choose the speaker area, run a cleaning mode, then compare the sound before and after. The app also works offline, so the core tools are ready when your connection is not. CLEANING MODES - Water eject tone at 165 Hz - Deep clean for heavy moisture - Gentle mode for regular care - Dust blast for blocked sound paths Speaker Cleaner - Eject Water uses low-frequency sound and vibration patterns to help push liquid from the speaker opening. You can target the main speaker, the earpiece or both, depending on where the sound feels dull. Haptic feedback adds a physical pulse during supported cleaning sessions. Manual mode gives direct control when you want to adjust the tone yourself. Auto-clean is useful when you prefer a guided session. Frequency control covers 20 Hz to 22 kHz, with sine, square, triangle and sawtooth wave options for testing different sound behaviour. SOUND TESTS AND RESULTS - Before and after sound test - Speaker health score with FFT analysis - Water drops ejected counter - Shareable cleaning result card Speaker Cleaner - Eject Water includes practical checks for daily use. Run a speaker test, microphone test, stereo test or balance test to understand how your phone audio is responding. A decibel meter helps you watch loudness, while the live system volume monitor shows the current output level. The app records cleaning session results and keeps a history, so you can see progress over time. A safe volume level indicator helps you avoid pushing sound too high during tests. If you need extra loudness, the volume booster can raise playback up to +18 dB where supported by the device and current audio route. SMART AUDIO TOOLS - One-tap speaker cleaning shortcut - Home Screen widget access - Siri and Shortcuts support - Apple Watch 165 Hz eject Speaker Cleaner - Eject Water is designed for simple routines. Add the Clean Speaker app intent to Shortcuts, start a quick clean from the widget or use the Apple Watch companion app for a 165 Hz water eject session. Smart reminders can prompt you to check the speaker after wet weather, workouts or frequent outdoor use. The 7-day speaker care programme gives a light structure to repeated cleaning. Progress tracking shows what has already been done, without turning the app into a complicated dashboard. Light Mode and Dark Mode keep the interface comfortable in different settings. EXTRA FREQUENCY TOOLS - Frequency generator for tone checks - Mosquito tones at 15, 16, 17 kHz - Voice recorder for quick samples - Offline mode for core functions The frequency generator helps create a clear tone for speaker checks, audio experiments and comparison tests. Mosquito repeller tones are available at selectable high frequencies. The voice recorder can capture short samples before and after cleaning, so you can review whether speech or playback sounds clearer. Some functions are available with a paid subscription. Premium access may include expanded cleaning tools, history, result sharing, reminders, widgets, watch features and advanced audio utilities. If auto-renewal stays active, your access continues automatically; to stop the next renewal, turn it off at least 24 hours before the current period ends. Sound-based cleaning can support drying and dust removal, but it cannot repair hardware damage or guarantee results after serious liquid contact. Avoid using high volume near your ears and follow your device manufacturer’s safety guidance.
