It seemed obvious then that the same formula would appear on the AppStore. However, it was not to be an official release. Instead it fell to Tapulous to bring the experience to the iPhone and iPod Touch with their successful Tap Tap series. The game has spawned many sequels and spin offs and has become one of the great success stories of the AppStore. Gameloft had a go too with Guitar Rock Tour, and we eventually saw the spiritual successor to GH make an appearance in the form of EA's Rock Band."
