What do you have in mind for the style and theme of the app?
We want to provide the app as white-label product to financial advisors, health care companies, retirement homes. that means we want to have a neutral design where colors can easily adapted and the customers logo can be integrated. furthermore - as it is for elderly people - we have a easy read mode i.e users shall be able to switch to a mode with bigger fonts. we have a first version of our app but it should look more modern and like a financial app (maybe to include a pie or similar chart). Attached a document with some examples of similar apps. I personally like the style of the last 2 pages.
As we want to have the design for the whole app I suggest to focus on the overview screen first. Time is pressing as we have a demo by the end of this month.
