An iOS app for peer-to-peer voice chatting

Multipeer Voice Chat

This app uses Apple's MultipeerConnectivity and AVFoundation frameworks to facilitate area-local peer-to-peer voice calls with up to eight users.

This app is not yet finished, but its core functionality is present. There is only one major known issue -- hitting the End Call button in the InCallViewController.

I plan to change the layout of the app significantly to improve usability.

Testing the App

This app requires multiple devices to show off its networking capabilities. To test, I reccomend running the app in a simulator and on a physical device at the same time. It's much less impressive if you have two simulator instances communicating with each other, as you'll only hear your computer's microphone input played back with a slight delay.

The unit tests and UI tests currently don't do anything.

State of the App

Things that work

Bugs / Things I want to change
