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 β up to 30kHz in Ultrasonic mode β 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 β 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 β the same technique built into Apple Watch β 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.

It is built entirely on Apple's Screen Time tools and runs completely on your device. Nothing is uploaded, tracked, or shared. THREE WAYS TO BLOCK β’ Scheduled β put apps to bed during set hours, like 10pm to 8am. β’ Delayed access β a short, calming pause before an app opens. Friction, not a wall. β’ Daily budget β a time allowance; once it is spent, the app rests until tomorrow. A LOCK THAT HOLDS YOU TO IT Turn on a commitment lock and you will not be able to weaken or switch a profile off until it expires β you can only make it stronger. It adds a real cooldown before you can change your mind, for the moments willpower alone does not cut it. You always keep full control of your device in Settings. QUIET, ENCOURAGING INSIGHTS See how often you chose to wait, your streak of steady days, and the time you reclaimed β all counted privately on this phone. PAY ONCE. NO SUBSCRIPTION. The free version gives you one full-featured profile, commitment lock included. Unlock unlimited profiles and ready-made templates with a single one-time purchase. No monthly fee, ever. β’ 100% on-device β no account, no ads, no tracking β’ Supportive, never shaming β’ Beautiful in light and dark Anchor is a calm, one-time-purchase tool for anyone who wants a firmer, kinder way to step back from their phone.
