Simon Barkow-Oesterreicher, Eckart Burgwedel, Martin Polak and Ilona Maslioukovskagia have developed a guitar teacher for your pocket. With the smartphone app 'Uberchord', guitar students can learn to play the guitar professionally anytime, anywhere. The app recognizes precise single notes and complicated chords - it also gives the learner feedback in real time. The exercises are constantly adapted to the learner's progress and also include drums and bass as rhythmic accompaniment and can be shared with friends. The developers' vision is to create a platform for guitar training on which every student can find a customized range of entertaining lessons.
