Has trapped water or pocket lint left your iPhone sounding muffled? Sona Clean Speaker Water Eject uses calibrated sonic sound waves to dislodge moisture and debris from your speaker grills—while packing a versatile suite of acoustic tools to monitor your sound environment day and night. From restoring muffled calls to measuring room noise and tracking bedtime disturbances, this all-in-one audio utility gives you full control over your device's sound performance. Core Features Sonic Water Ejection: Generates sweeping resonant frequencies designed to vibrate trapped moisture out of the bottom loudspeaker and top earpiece safely. Speaker Dust Remover: Uses specialized vibration pulses to dislodge fine lint and pocket dirt without resorting to risky pins or compressed air. Custom Frequency Generator: Dial in an exact sine tone anywhere from 20 Hz to 20,000 Hz for targeted acoustic unclogging or audio testing. Real-Time Decibel Meter: Accurately measure surrounding sound pressure levels (SPL) in decibels (dB) with peak and average noise readouts. Sleep dB Tracker: Run an overnight acoustic monitor to track noise spikes, snoring, and room disturbances while you rest, complete with a morning noise summary. Speaker Clarity Test: Right after cleaning, play a test tone through each of the four outputs in turn—plus an optional 40–120 Hz bass sweep—to check stereo separation, bass response, and overall audio sharpness. How to Eject Water & Dust Disconnect any connected Bluetooth audio devices or headphones. Set your iPhone's volume to 100%. Hold or place the phone screen-down so the speakers point toward the floor. Start the cleaning cycle, let the sonic sweep run, and wipe away any ejected moisture with a dry microfiber cloth.

Verdict
The clearest difference is review sentiment: Sona Clean Speaker Water Eject at 100% against Reverse Singing's 25%. Sona Clean Speaker Water Eject also leads on update cadence (daily vs fortnightly). Reverse Singing's advantage is ads (none vs shown) and ratings volume (7.9K vs 9). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Reverse Singing sells 6 in-app purchases, starting at $4.99 per 7 days and Sona Clean Speaker Water Eject sells 4 in-app purchases, starting at $10.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Reverse Singing holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Reverse Singing has 7.9K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 25% of Reverse Singing's written reviews are positive against 100% of Sona Clean Speaker Water Eject's, so the app with the better star average is not the one people write more warmly about.
Reverse Singing ships an update fortnightly, Sona Clean Speaker Water Eject daily. The most recent releases landed on November 12, 2026 and November 10, 2026 respectively.
