About One Button Megaphone

Your Phone as a Megaphone with One Touch! Send Phone Mic to External Speaker!

Simple, easy to use megaphone app. Use the microphone in your phone to send your voice to an external speaker with this easy to use mic to speaker app.

Connect your phone's internal microphone to an external speaker (wired or Bluetooth), press the button and you can now use your device like a bullhorn. Easily make loud announcements with your phone's mic and an external speaker. No additional AV equipment required.

*** If the app says your device isn't connected to a speaker and you think it is, it is possible to disable the warning by going into settings (settings button at bottom right) and selecting the "Remove external speaker check." checkbox. Note that this is not recommended, because it will allow the app to use the internal phone speaker, which causes horrible feedback. You have been warned.
