SoundTowel app: a 7-day plan to bring your speaker back

Planned for iOS and Android. Not released yet.

One round of a cleaning tone clears what sits in the speaker grille today. What is further in takes longer: Apple says water in the port can degrade speaker sound until it completely evaporates. The SoundTowel app is planned as a 7-day cleaning plan that comes back to the speaker on each of those days, and a push reminder tells you when the next session is ready.

Why one round is often not enough

Water keeps drying for hours

Apple says a wet iPhone connector can take up to 24 hours to dry fully, and a muffled speaker stays muffled until the water evaporates.

The real check comes later

Sound right after a splash is not the final answer. A check on a dry phone, days later, tells you whether anything is left.

Dust keeps collecting

Pockets and bags keep adding grit to the grille, so a clean speaker today is not a clean speaker next week.

The 7-day cleaning plan

Each session has its own sound. The next day opens on the following calendar day, and a push notification tells you it is ready, so the plan doesn’t depend on remembering.

DaySessionWhat it is for
Day 1Water removalBasic cleaning frequencies for water and dust you can see in the grille.
Day 2Deep cleanSeveral frequencies in one session for what the first day left behind.
Day 3Intermediate cleaningA lighter session on medium frequencies to keep the speaker clear.
Day 4Speaker checkA functional test of the speakers after three cleaning days.
Day 5Detailed diagnosisA closer check for remaining particles and uneven sound.
Day 6Pre-finish cleanA quick refresh for new dust.
Day 7Performance checkA final clean and check of the speaker.

Free on the website or in the app

The website is free and stays free. The app is for the part a web page can’t do: come back to you tomorrow, set the volume for you and keep track of the plan.

What you can use today

Everything on this website works now, without an account. The water eject tone plays 165 Hz for a muffled speaker after water, the speaker cleaner adds a low-frequency dust mode, and the speaker test checks left and right channels with a full sweep. On Android, the vibration test checks the motor.
