Finally :)

I have been waiting for this ever since I got my iPhone and it's finally here! It works and does everything that it's suppose to do and is easier than going through the browser. I like checking my balance once a day and this makes it much easier and convenient for me. Thanks SIS for this feature and I look forward to seeing what else you can do to make my banking better :)

Please update for iPhone 5!!!!!!!!!

Easy to use, but basic

Good app, user friendly and no bugs or glitches as of yet. It makes transferring money and checking your balance easier than going through a browser and is faster than the mint app to update, however doesn't display things such as cash flow and how much you've earned versus what you've spent.

A must for sis customers makes banking easy and puts account information, balance inquiries and transfers at your fingertips! The automatic sign out feature keeps all your data safe when u set your phone down for a quick second. Highly recommend.
