Good so far. Needs improvement
There should be the ability to use swipe gestures to return to a previous screen or page (the ability to swipe from left to right), instead of reaching to the upper left and pressing the return icon. Also on the invoices page, the total amount owed for all items is not displayed there, it should be displayed at the top. App is also a bit unstable and animation isn’t as fluid as it should be. But good job so far.
