This the third app that enables children to explore and enjoy creating patterns with percussion instruments, record and playback. This will have a much more complex interface to facilitate exploration of diverse instruments, setting, and play patterns as well as recording, playback and sharing of such recordings. We intend to create a simple 'Home Screen' that has these three applications for the children to use. Our expectation is that with some reasonable use of these three Apps they will be ready to move on to a standard Android phone competent enough to explore and learn the depth of offering in such a phone.
