Exactly what I wanted!!! Includes both sexagesimal mode (when the phone is in portrait — vertical — position) and binary-coded decimal (which appears when the phone is rotated to landscape position). It even has a "Hints" mode, which shows each dot's value. I would pay for this! But then, I'm sort of a geek. 😊

Outstanding! Easy to use, easy to understand. I wish this could be a widget.

Nice Clock, and it makes it easier to understand binary number and become nerdy!

I'm sorry, but this is just useless. You need to open it to see it, and you can't change it or do anything at all. No widget, nothing. There's no way to look like a cool nerd if you have to find and open the app WHICH SHOULD BE a bright sleek intriguing widget on your home screen that people constantly ask you how you got so cool to attain it at the very least, and a 4-Star baby breakfast with Michael Obinary himself at the buffest.
