Update: Thanks for the info 5 stars ! Just refinanced from another bank. This experience was so easy. GSB makes the opening of extra accounts so easy (even joint accounts). The app is very easy to use and navigate. Login is a breeze with finger print signon and site security (2fa) is great and responsive. The app is 98% perfect and just needs: * ability to customise account order * ability to see further account attributes (e.g Offset details).

Hi Joel, you are able to see your scheduled payments/bills in the app! If you tap the three bars in the top left after logging in, go to 'Payments & Payees', then 'Scheduled Payments'. About the customisation of account order and seeing offset details, we'll lodge this to our Digital team as a suggestion to consider! Thanks, Great Southern Bank.

The app has constant errors and is slow, it is also lacking features that the website has, such as accessing banking records and is overall a worse experience than the website, along with more errors, and currently if you click the products screen it gives you an error and you have to reopen the app to do anything else.

I have had nothing but issues for months with this app. I have been a CUA/ Great Southern customer for over 20 years without issues. Now I cannot login in via the app, since an update a few months ago. it's now a pain, and have to go through mobile website, which is hard to use on a phone screen. talked to GS, if I can't get a fix, my next step is to move... I have the same Android phone, everything works seamlessly. Something needs to happen, or we will leave.
