Easy-Peasy App to Use!

This app is both easy and functional. It seems to fit the need of any and all personal banking functions.

Old app better

The app should List all transactions (transfers, deposits, checks, debit card) within the last 30 days, not just that month. when I logged on on the first of the month it shows no transactions, well of course because it's seven in the morning! But I know there are transactions from yesterday which was the 31st and those are the ones I want to see. Also it will show you the available balance but won't let you see the pending transactions so you don't know what to account for. I had to log on to the full website to find out the information I needed...annoying! Then I tried to do a transfer and it kept telling me it failed. However when I logged onto the full website (again) and clicked on "all transactions" (which is the only way you can see any pending transactions) it said that they all went through and showed I had multiple transfers! They should have left the old app it worked great!
