## What is Unda?

Unda is a water eject and speaker cleaner app that pushes water out of your iPhone speaker in 60 seconds and shows you whether it worked. It is also an audio test kit: cleaning programs, speaker and microphone tests, a tone generator and a decibel meter. Free to download, no account, no ads.

WATER EJECT
• The 165 Hz tone that shakes trapped droplets out of the speaker grille, the same trick as the famous shortcut and Apple Watch Water Lock
• Programs for every case: Water Eject, Deep Clean, Dust Removal, Turbo, Earpiece, Headphones and Weekly Care
• Light, Normal or Intensive, 1 to 3 cycles with a pause in between
• Tuned for your device: iPhone, compact iPhone or iPad
• Clear instructions: speaker down, volume up, headphones off, and a slider to set the volume to 100%

KNOW THAT IT WORKED
• After every cleaning, play a test sound and answer "Sounds clearer" or "Still muffled"
• Your answers are saved to a history, so you can see whether a second cycle helped
• Tips for stubborn water and when a speaker is beyond cleaning

SPEAKER AND MICROPHONE TESTS
• Frequency sweep from 20 Hz to 20 kHz to hear crackle or dropouts
• Stereo test: left, right or both channels, with a 440 Hz tone or 55 Hz bass
• Earpiece test for the call speaker
• Microphone test: record 4 seconds and play them back
• Headphones and external output test

TONE GENERATOR
• Any frequency from 1 Hz to 25 kHz: swipe, slide or step by 1 or 100 Hz
• Sine wave for cleaning and hearing checks, plus square, triangle and saw
• Left, right or both channels, volume, auto sweep and an auto-stop timer
• Presets: water eject 165 Hz, sub-bass, tuning A4, speech, hearing checks, mosquito and dog whistle frequencies

NOISE METER
• A-weighted decibel meter with the dominant frequency, minimum, average and maximum
• Live spectrum, history chart and reference levels from a whisper to a jet engine
• Calibration offset to match a reference sound level meter
• dB Camera: photos stamped with the noise level, date, time and, if you like, your city

ONE TAP FROM ANYWHERE
• Siri: "Eject water with Unda"
• Lock Screen and Home Screen widget
• Weekly care reminder
• iPhone and iPad, light and dark mode, 32 languages
