Muffled speaker? Phone got wet? SonicEject fixes it in 30 seconds using precision sound frequencies — no shaking, no rice, no waiting. Just tap Clean and let the tone do the work. HOW IT WORKS SonicEject plays a carefully tuned sine wave that sweeps between 140 Hz and 180 Hz — the same frequency range used by Apple's own Water Eject feature. The vibration physically dislodges water and debris from your speaker grille, restoring clear sound. SPEAKER HEALTH CHECK Not sure if your speaker is muffled? Run a Speaker Health Check first. SonicEject plays tones across 5 frequency bands and guides you through rating your sound quality — so you know exactly what you're dealing with before you clean. KEY FEATURES • Fix Muffled Sound — precision sweep clears water and debris in one cycle • Speaker Health Check — diagnose your speaker before and after cleaning • One-Tap Clean — 30-second cycle starts automatically • 140–180 Hz Sweep — optimal range for dislodging water from speaker meshes • Visual Progress Ring — watch the countdown in real time • Haptic Feedback — vibration cadence synced to the sound wave • Background Audio — continue cleaning even if you lock your screen • Works on All iPhones — speakers, bottom grilles, and EarPods SPEAKER CLEANER PRO • Unlimited 30-second cleaning cycles • Unlimited Speaker Health Checks • Full 140–180 Hz frequency sweep --- Results may vary by device and amount of liquid exposure.

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.

Verdict
The clearest difference is update cadence: Water Eject at every 9 days against Crisp's every 2 months. Water Eject also leads on iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
