One Button Megaphone

Simple, easy to use megaphone app.

Connect your phone to an external speaker (wired or Bluetooth), press the button and you can now use your device like a bullhorn.

*** 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.
