Tap Pad for iOS

Music Hackday Toronto 2013 - iOS based Tap Pad (see web version here)

Note: This is a universal app and works for iPhone and iPad

Made by Dmitri Cherniak (@dmitric)

How to get it running

git clone
pod install
open TapPad.xcworkspace

The only external dependency is AFNetworking and I use CocoaPods to load it in. You need CocoaPods to build this project.


Just tap on the grid and get started!
