Liquid Wave - Tone Generator

Liquid Wave brings together guided speaker-cleaning tones, tone generation, stereo testing and a relative sound meter. QUICK CLEAN — FREE Use Quick Clean for a guided tone pattern intended to help loosen water trapped in your speaker. Follow the session timer and audio-route information, with Pause and Stop controls. The free mode includes advertising. LIQUID WAVE PREMIUM A weekly or yearly subscription unlocks Smart Sweep, Deep Sweep, the Tone Generator, Relative Sound Meter and Stereo Test. Premium also removes advertising throughout the app while your subscription is active. SMART SWEEP AND DEEP SWEEP Choose additional guided cleaning-tone patterns. Results vary by device and circumstances; no mode guarantees water removal or repairs damage. TONE GENERATOR Choose a frequency from 20 Hz to 20 kHz using the slider or numeric keypad. Select sine, square or triangle waveforms, set a duration or play continuously, and watch the waveform display. STEREO TEST Check left and right channels independently, in sequence or alternately, with on-screen labels and confirmation. RELATIVE SOUND METER View minimum, average and maximum relative sound levels using your microphone. This is not a calibrated decibel meter. Microphone audio is processed on your device and is not recorded, saved or uploaded. SUBSCRIPTIONS U.S. pricing: USD 3.99 per week or USD 19.99 per year. Prices in other regions may differ. Both plans provide the same Premium features. The weekly plan offers a 3-day free trial for eligible users, then automatically renews at the weekly price shown before purchase. The yearly plan has no free trial and renews annually. Local prices and eligibility are displayed in the app and Apple's purchase confirmation. Payment is charged to your Apple Account. Subscriptions renew automatically unless canceled. If you do not want a trial to renew, cancel at least 24 hours before it ends. Manage or cancel subscriptions in iOS Settings > your name > Subscriptions. Restore Purchases is available in the app. Deleting the app does not cancel a subscription. SAFETY AND PRIVACY Liquid Wave cannot repair physical or water damage or waterproof your device. It does not automatically raise system volume or play hidden background tones. Keep volume comfortable and stop if sound causes discomfort. If sound quality does not improve, allow the device to dry naturally and consult a repair professional. No app account or sign-in is required. Settings and cleaning-session history stay on your device. Google AdMob supplies ads in the free mode, AppsFlyer measures installs and launches, and Apphud manages purchase status and restoration. These services process device and usage information as described in the Privacy Policy. Premium removes ads; it does not disable all purchase-status and installation-measurement processing.
