Crisp vs DryWave

Clear water. Test your speaker. Verify the result. Crisp uses targeted sound frequencies to help eject trapped water and dislodge dust from iPhone and iPad speakers. Then it listens with the microphone to compare real Before/After dB measurements—so you can check the result instead of guessing. NO ADS. NO ACCOUNTS. 100% OFFLINE. Is my data private? Everything runs on your device. Nothing leaves your iPhone or iPad. No accounts, no analytics, no ads, no tracking. How do I get started? 1. Place your device face down on a soft surface 2. Set volume to maximum 3. Tap Start Eject and wait 3 minutes What can I do with it? - Eject trapped water using a 165Hz tone, or switch to Dust mode to shake out lint and debris - Choose Normal, Turbo, or Deep intensity for a faster or more thorough clean - Find your phone's exact speaker resonance point with Resonance Finder for a stronger clean - Compare a real Before/After dB reading, not just a guess, to confirm the cycle worked - Generate any tone from 20Hz to 22kHz — up to 30kHz in Ultrasonic mode — with sine, square, triangle, or sawtooth waveforms - Test speaker frequency response with bass (80Hz), mid (1kHz), and treble (8kHz) presets - Run stereo balance (left/right) tests on stereo-capable devices - Check your microphone for blockages with a one-tap diagnostic - Measure ambient sound level with the built-in dB meter - Sweep frequencies automatically to dislodge stubborn dust particles - Take a structured hearing test across the audible range and save your audiogram - Save your favorite frequencies for one-tap recall - Set a cleaning reminder and track your streak over the past 7 days - Ask Siri to eject water, hands-free - 100% no ads, ever — most speaker-cleaning apps are free with ads until you subscribe; Crisp never shows one What devices does it work on? iPhone or iPad running iOS 17 or later. The same audio principles work on any built-in speaker. Why use Crisp? Speaker grilles trap moisture from sweat, rain, pool splashes, and humidity. Dust and pocket lint accumulate over time. Crisp uses sound vibration — the same technique built into Apple Watch — to physically dislodge particles without opening your device or using cleaning tools that can damage internal components. Does it really work? Sound vibration ejection is a well-documented technique. Results depend on how much water is trapped and how recently. For best results, run the cycle within an hour of water exposure, repeat 2 to 3 times, and keep the device face down throughout. How much does it cost? Download free. Optional Crisp Pro plans and any eligible introductory offer are shown in the app using your local App Store price. You can manage or cancel subscriptions anytime in Settings.

Dropped your phone in water? Muffled speaker? DryWave plays precisely tuned sound to push water out of the speaker grill — the same 165 Hz principle the Apple Watch uses to eject water. ■ Water Eject One tap plays a 165 Hz pulse cycle that physically pushes water droplets out. Point the speaker down, turn the volume up, and run 2–3 cycles. ■ Dust Clean A frequency sweep (60 Hz–8 kHz) vibrates dust and debris loose from the speaker mesh. ■ Manual Tone A frequency slider (50–15,000 Hz) for full control — great for testing your speaker too. ■ Home screen widget Add the 1×1 DryWave widget and eject water with one tap — right from your home screen. ■ No nonsense • The clean button is never locked behind an ad • No subscription — remove ads forever with one small purchase • No account, no permissions, works fully offline Note: DryWave helps eject water and dust with sound. It cannot repair hardware damage. For heavily water-damaged devices, power off and see a professional.
