Hello,
I would like to share ‘CodeHorizon’ with the CodeChef community. CodeHorizon helps coders like us to keep track of algorithm contests on sites like CodeChef, CodeForces, HackerEarth, HackerRank, TopCoder and few others. You’ll be able to view list of all the ongoing and upcoming contests on these sites, and receive notifications for upcoming contests while being online or offline.
Earlier the app was available for iOS devices only. I have managed to develop an android version, and have published it in the google play store.
App Site : http://www.star-lord.me/CodeHorizon/
Google play link : https://play.google.com/store/apps/details?id=com.chintanghate.CodeHorizon
ITunes link : https://itunes.apple.com/in/app/codehorizon/id925056167?mt=8
I hope this app is of some help. Please let me know if you have any suggestions on making the app a bit more useful.
