WaterOut
Read full descriptionHide full description
WaterOut is a single-purpose mobile utility built for one job: helping clear water from the phone speaker after a splash. It is intentionally focused, with a simple Eject and Stop flow made for quick action and no extra menus. When you tap Eject, the app runs a high-volume audio sweep for 14 seconds around 165 Hz. The sweep creates controlled vibration in the speaker cavity to help loosen trapped moisture so it can move out. You'll see a clear progress indicator and get haptic feedback as the cycle runs. Tap Stop any time to end the action early. For best results, place the phone in a dry area, keep the speaker facing downward, and let the cycle finish when possible. Keep the phone away from ears and children while it is active. This is a convenience tool, not a repair service and not a medical or safety certification app. Real-world results vary by model, amount of moisture, and how soon you use it after exposure. WaterOut does not claim waterproofing, guaranteed drying, or guaranteed full water removal.
