About this app

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.

Ratings and reviews

Nice, straight forward to use app. For a basic uncomplicated way to talk into your device and broadcast it onto a bluetooth amplified speaker, hits the mark There is about a half sec delay but as I read other like apps, it is out of control of the developer. So far the app has proven to be stable. Remain some distance from the speaker to reduce feedback. Wish list while still keeping app simple: * Add a volume control slider * Add a Quick Play feature in UI with one click to play that .mp3

I'm very glad to have discovered this megaphone app! I already have an amplifier, but no mic. So now all I need to do is simply hook the phone up to my amp and turn on the megaphone. Also, I discovered that I can use it as a line in mic for my Mac and PC, again saving me from having to purchase and new mic. I do wish it would run in the background, as it could be useful when capturing audio from other apps. Great job!

Slight echo when using. No feedback cancellation. No ambient noise cancellation, i.e. wind. But it does exactly what it advertises, and for free, ya can't beat it. All negative reviews have too high of expectations.
