The team behind this app deserves highest level of tribute. The perfectness in IRCTC site resembels in app as well. In fact, they made this app more powerful, user friendly.
Especially, if you would like to book tatkat tickets, choose this app than website. Its much faster and easier. Here, we can also add passenger names in master list under my account tab available in the menu, and just dump them when you book the ticket by checking the box.
The only limitation in the app is you can only book six tickets per month. If you try to book 7th ticket, your amount will be deducted and transaction will fail. Don’t worry, the amount will be credited back in two to three working days.
