What's New in Version 5.2.5

This update includes bug fixes and improvements.

For certain devices, iPad Air and iPad Mini 2, check out our multitasking enhancements. You can run our app and others at the same time.

iPhone 6s or 6s Plus user? We didn’t forget you, check out 3D Touch on our app and you can now peek and pop on Account Cards or RDC History!

iPhone 6 Plus, iPhone 6s Plus, and iPad user? We created a new split pane view for accounts so that you can see your account balances and transactions at the same time! We want to make it easy for you to find what you are looking for. Note: iPhone 6 Plus and 6s Plus users, you have to hold your phone in landscape orientation to see this.

And that means, we now support landscape orientation on iPhones!

Great app

Love that Touch ID logs me into the app. It's pretty straightforward to use. I have noticed that at times total money in my account doesn't reflect exactly with what the main source website says. Also, my only other issue is that if you set up alerts they are usually about 2 days late from when the transaction happened. Seems a little slow but maybe that's just how long they take to clear. Idk good app

What a bank app should be!

Very easy to use and very helpful. I live an hour from my branch and this saves so much time and hassle!

No complaints

Easy app. I really like it.
