Irctc is now working on its applications beta version but frankly speaking the current version is so weak and unstable. Takes years just to show the trains of required routes. Very slow working app. Needs a huge amount of development and improvement.
User interface is very poor, the app only shows the trains which are particular to the dates, but not those which are on aother days. Whenever I log out of the app it takes me to a lot of ads pages, and then I have to clear the caches every time I use the app.
Important is application do not support all kinds of payments which are available on website of irctc.
The working version of app should launch soon for a better irctc versions.
