I am working on an iPhone app. I am in the early stages of designing the structure.
I will be using word department as a node in the information architecture structure of an app.
I encountered a rather rare (or I think it's rare) issue with information architecture in the app. I am trying to design the navigation system of the app while having 2 main departments in the app. The problem is that I would not rather use the tabs, since 2 tabs look weird (and I haven't really seen an app with 2 tab bars) and they take too much space.
Systems, which I found are used for splitting departments in the apps are:
1. TABS Usually used for more than 2 app departments, like foursquare. Depts: Friends, Explore, User
2. FEED STYLE Usually used for 1 app dept. Dept: Feed
And many others which are usually designed for >= 3 depts
My question is are there any other alternatives to presenting structure of the app in iPhone apps? I would of course rather go for a pattern, which is well-known and not design my own.
And the second if you had 2 main depts in the app how would you present it in the iPhone app?
