My team binaryhackers built an android application for the Codechef API hackathon.
Name of the Application: Chef On Phone
Description: Our app allows using codechef on your phone. Using this app you can see ongoing contests, future contests, contest problems, practice problems, read problem statements and solve the problems in the IDE built-in inside the app. You can also set reminders for upcoming contests. Download the code from IDE to make submissions on codechef. This will help users to use codechef whenever they want to be it while travelling on bus/metro etc or during boring lectures.
