This is a great app!

I understand the frustration of having to adjust to a “new thing”. Yes, I had to go to the nearest branch and show my ID so I could get my membership # to be able to get this thing up and running. I had tried calling but that was a disaster. Popping into the bank literally took one minute! It was so worth it!

What I love, love, LOVE about this is the Money Management section. I was able to get the balances of my three different bank accounts and four major credit cards all in one place. So rather than logging in an out of different apps and having to do the math in my head I can log into Sound CU and see it all. It’s great!

Disappointed Beyond My Ability To Express It Here

Sound Credit Union found a way to give their users a terrifying bad transition experience from their old mobile banking system to the new one, in which poor instructions and poor communication made it completely unclear how to get back in when the system did finally come back up.

The new app is the same as the old one. They put a new UI on that simply makes it look more like an excel spreadsheet.

What’s particularly frustrating is that the beloved text banking is completely gone. I used to immediately receive an alert any time any transaction occurred in any of my accounts. I always knew my balance and when a transaction took place, so I was confident I could stop fraud right away and be aware of my financial situation. With the new mobile banking and this app, notifications are limited and delayed. There are none available at all for the credit card, which was the entire reason I switched to Sound Cu In the first place. If there was a way to roll it all back to the way it was before, I’d highly recommend it. Sound CU - Feel free to get in touch with me to discuss further.

Probably one of the worst apps I’ve EVER come across. The old app was just fine. If they wanted to update it, they could’ve developed an app that didn’t make you verify check deposits that don’t need verifying. They could’ve developed an app that didn’t give an error message once or twice a week when trying to sign in. They could’ve developed an app that didn’t have an unnecessary large amount of “system updates” every month. Transfers within my accounts don’t immediately show visible like they used to with the old app. Pending charges and current/available balances sometimes just don’t add up when looking at the balance sheet. Yet somehow after a few days everything evens out??? The problems are continuous and eventually will lead to account closure. There are MANY credit unions out there that have a user friendly app available.
