Is your iPhone speaker sounding muffled, quiet, or distorted after falling into water or gathering dust in your pocket? Do not use rice or needles! SonicPro is an advanced acoustic utility that uses precise sound wave frequencies to safely expel liquid, dust, and dirt from your device's acoustic cavities. Restore your speaker's original crystal-clear sound in seconds. CORE FEATURES: WATER EJECT MODE Uses short, heavy acoustic impulses (165Hz) to physically push water drops out of the bottom speaker. Perfect for accidental drops in the sink, pool, or rain. DUST REMOVAL MODE Lifts and disperses light dust particles and pocket lint using high-frequency vibration sweeps. DEEP CLEANING MODE A maximum amplitude sweep from 100Hz to 1200Hz that combines both techniques to tackle stubborn dirt and heavy moisture. MANUAL SIGNAL GENERATOR (PRO) Take full control. Manually adjust the frequency from 80Hz to 1200Hz using a precision slider. Choose whether to route the sound through the Bottom Speaker or the Top Earpiece for targeted cleaning. SonicPro is designed with a stunning, user-friendly interface and real-time particle visualization, so you can see exactly which mode is active. --- PRO ACCESS (PREMIUM) Upgrade to SonicPro Premium to unlock: ⢠1200Hz Deep Clean Mode ⢠Manual Frequency Generator (80Hz-1200Hz) ⢠Top Earpiece Sound Routing ⢠Completely Ad-Free Experience ⢠Unlimited Daily Ejections Payment will be charged to your Apple ID account at confirmation of purchase.

Verdict
The clearest difference is ads: ColdStart at none against SonicPro's shown. ColdStart also leads on update cadence (daily vs weekly). SonicPro's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.1). On price and in-app purchases there is nothing between them.
