Ratings and reviews

This app is garbage. They do maintenance every single day and when most do it in the middle of the night, they do it between 8 and 10pm. It causes my balance to be off in the app, and most times, it says I have hundreds more than I actually do. Other times it says there is an error and won't change even after a purchase. We were a First Merchants transfer and I am not happy with this O2 app at all.

So far, I have not had any major issues with the app or this bank since the name changed in December 2024. MY only complaint is that I need/would like for the bank to increase the limit amount that can be Zelle. I was trying to pay a business and I had to do it in 3 transactions over 3 days!!! AND once you have Zelle the max($600), that's it for the day. INCREASE THE ZELLE AMOUNT LIMIT, THANK YOU. I have business to take care of.

Unreliable. When you purchase something, it takes over a day for it to register that you've spent your funds, doesn't update your savings correctly, and doesn't notify you of most transactions.
