I have a question about designing the UX that requires a large amount of data to be entered by the user upon signing up for an app - needed as the app cannot function without this data - how can this be designed in a simple fashion. Furthermore the app needs to be designed for the iPhone hence having a small screen to enter a large data set. Because they have to enter this info upon signing in they might be overwhelmed and turned off to use the app - need to avoid that.
The data set is financial in nature (and thus can be perceived as boring) including things like salary, 401k deductions, marital status, student loan amount, etc.
The closest app that I saw was TaxCaster. https://itunes.apple.com/us/app/taxcaster-mobile/id346184215?mt=8
I found it to be cumbersome as an end user on the iPhone, several screens to navigate. Our app is not even close to this much data but would say its a fair amount of data entry.
P.S. I am not a UX or iOS developer but working with an iOS developer on identifying a flow.
