ZYX is an iPhone app by JODI: http://jodi.org
Specifically, we noticed the user interface of your app is not intuitive and could not be navigated. For example, it asks the user to turn right ten times. Simply turning the phone to the right did not increase the count. After moving the phone in several directions it began counting, but repeating the same task would only allow the count to go up to 4, at which point it looped back to provide the same command to ‘turn right ten times’.
