I have been using this app since one and a half year, I installed it form the play store, all you need to do is fill your detail in this and you are all set to see all your transaction history and balance in one click, You have to fill your crn(customer relationship number) allotted to each customer from the bank every time you want to check your account.
This application is very useful to me, Its on my phone and very convenient to check my account details whenever and wherever I want to check without any safety issue, In my phone I update it regularly for a hassle free usage, otherwise You can face any lagging issues.It also takes very less space in my phone memory as well.
I would highly recommend this application to everyone.
I am very happy with this kotak bank app.
