I'm trying to inch my way towards building a data collection app for a specific application. Eventually I want to have drop-down and manual text entries, building a dataset that I can export as a CSV and manipulate further in Excel.
I've used some apps like Fulcrum, but eventually I'd like to add some more functionality to the app. Basically I'm trying to figure out how these apps are storing the entered data, then pushing it to a server when internet access is available. What are some general options that I should explore to do this magic?
Thank you!
