Can I use the Alliant mobile banking app on my tablet device? In order to provide the best mobile banking experience, we are making updates to the Alliant mobile banking app in the coming months. The mobile app will still work on iPad and Android tablet devices with the supported operating system versions, but will display with the app layout you have grown accustomed to on your smartphone. You can continue using the app on your tablet, but the display may not be optimized for your tablet device's larger screen size. Tablet users can also use the responsive Alliant online banking platform, which is optimized for tablet devices.
