Alarm Feature
I love the design. One problem though. There no way to shut the alarm feature off when the application is on. So if you do not want to be awoken, the application must be off. This prevents the clock face from being visible at night. One fix is an on/off button or better yet if the alarm would ring only when the alarm face is shown. I hope the designers fix the problem.
