I am using this app from last 7 years but earlier it was not so much easier to use this website but once they updated this website it is very easier to book the tickets and make the payment in different modes and so many additional features added like tracking any trains across India, chances of confirmation % for waiting list and Tatkal tickets before booking the tickets, without login into IRCTC in main screen itself we can check the availability of seats just entering FROM and TO station and once tickets is booked you can sort out by upcoming journey in separate screen to avoid confusion.
