Ive recently completed the sound design for these apps. I first worked with this developer last year, composing some music for an advertisment. There is not too much to explain about the project, it was just the creation of some simple sounds for the app. If you have children (or very child like humor), you might like to download these for them.
One of the things I love most about this job is the range of different projects I can be working on, In this case I went from writing a very soft and delicate string arrangement for a pitch to producing some fart noises all within the same week.
