Truly underrated app

I looked around the app store for a good twenty minutes trying to find an app that will simply amplify my voice through a speaker in real time. Found a handful of good ones, but this is the first one I found that did it for free, and did it well. I found another handful of good ones, but they all charge for something, like just to be able to use it through Bluetooth. Stop complaining people, this app's simplicity is what makes it great. If you want more features, get ready to dish out some cold hard cash, because all these other apps won't do it for free.

Needs Floating toggle or split screen, noise filter

If using this for livestreaming it can be a pain. The forced screen orientation gets annoying when there’s no need for it, and you can’t use it in split-screen to toggle it on/off when needed. A small floating toggle like some video apps use would be useful.

If you don’t have an external mic it picks up every swish and tap on the device which is really annoying. Making it so it only picks up on non-device noise would be appreciated too.

Also a way to listen to music while talking. Just lower music volume if sound is coming through the mic or something.

Developer Response ,

Thanks so much for the thoughtful feedback. The current version now supports iPad rotation and split screen as well as multi app audio mixing.

Stethoscope type

Used it with my LG stereo Bluetooth headphones as a Stethoscope to listen to parts of my auto while working on it. Built in delay is to prevent feedback between iPhone's microphone (which uses the iPhone's earphone next to the front camera as the microphone) and whatever speaker or amp you hookup either through the earphones jack, or (what I like) via Bluetooth stereo headset. (I'm using iPhone 5 with this.)
