Coder's Calendar - Android App for Coders [Update: Material-ish design]

A few weeks ago,I had posted about a Chrome and Firefox extension that I had created called Coder’s Calendar which displayed a list of live and upcoming coding contests.(read about it here)

I’ve created and published an Android app of the same.

It is available for download here :

I am using Coder calendar on firefox but it is not showing hackerearth contest ,in the settings i have
added hackerearth also but then also it is no showing hackerearth contests.

Nice tips, thanks

dows it support homescreen widget… there is already a very nice coding calendar app on android but it does not have homescreen widget

@ankursmooth : At present no. It does sound like a great idea!
What would you want to have in the widget?

@nishanth_v this app is already there with many features like reminder, notifications etc . you app is a good effort but seems to have nothing new… For widget :add some(10-20) entries to your android calendar and then place calendar widget on your homescreen and you will see scrollable widget. if you can do the same to your app’s widget then it will be really new feature and differentiate your app from the Coding calender app.

I’ll see what I can do

It must have been a temporary server error.Or do you still have this problem?

I am still having the error in my calendar none of the hackerearth
contests are showing.

Which version of the extension are you using?Is it v0.3.0.1-signed ? That is the current version.If not try updating it and let me know if the issue persists.
