About this app

Muffled calls, a wet grill after a swim, dust from a pocket — Memvra is speaker care with measured tones, not a random YouTube rumble.

WHAT IT CLEANS
Loudspeaker, earpiece, microphone, and wired or Bluetooth headphones. Each target has its own frequency, volume, and a short safety note. Hold the grill out, keep earbuds off the ear, point the mic port down.

PROGRAMS THAT MOVE MATTER
Water eject uses a 165 Hz sine in 15-second pulses with a 5-second rest so liquid walks toward the mesh and the coil can cool. Dust lift holds 200 Hz to walk dry particles out of the cavity. The earpiece gets a shorter, quieter 280 Hz because that driver is small and close. Deep restore stacks water, dust, then a log sweep. Smart clean follows your last scan, or deep restore if you have not scanned yet. Manual mode lets you set any tone from 100 to 2500 Hz.

LAB, THEN CLEAN
Contamination scan plays calibrated tones and listens with the phone microphone to see where energy drops. You get a map across bass, voice, and treble — an estimate of the speaker-plus-mic loop, not a studio certificate. Watch the change before and after a session. Mic test records four seconds on the device, shows input level, and plays it back. Nothing leaves the phone.

SAFE VOLUME, REAL PAUSES
Studio level is about 60–80 percent. Maximum volume does not push more water. It only heats the coil. Pulse, then rest. After salt water or sweat, eject, dry for a day, then a light dust pass. Cotton swabs crush the mesh.

HABITS THAT KEEP THE GRILL OPEN
Weekly, biweekly, or monthly reminders in the language you picked in the app. Auto volume raises media to about 70 percent for a session and puts it back. Repeat any session from history. Dark cinema or light studio theme.

English, Russian, Spanish, Portuguese, and Chinese. Follow the system language or pick one in settings. No account.

This app may show ads. Ads stay off during a clean, a scan, and a mic test so a session is not cut mid-tone.

Memvra will not replace a repair shop if the driver is torn. It is a careful way to move water and dust you can still hear sitting in the grill.
