I being a SBI user, love the priviliges which i enjoy almost everytime. With the wide network of ATM, SBI also provides safe online transaction but this app is a jack of all trades.
One can simply use and see the basic account details also in this app, and can also do transactions and recharge through the same app.
It also has a mpassbook which helps maintaining account easily, i also love the imps transfer option in the app since it helped me a lot to transfer money in my friends account. Basically this app is a really helpful app to manage my savings account and i dont have to visit much to the branch since all the details can be seen and managed from this only.
