What UI design should I use for a smartphone app?

Question

On desktop platforms, using the system's control styling, etc. is a very common practice and changing it ("theming") is usually looked down upon unless the application specifically calls for it (like a themable music player).

However, on mobile platforms (smartphones), I've noticed that this isn't all that common. Many apps prefer to throw the platform styling out of the window and simply use their own. Also, apps that use their own styling appear to be "better" than those that use the system styling. (I'm talking about Android apps in specific, and about my own opinion.)

So, my question is, what should one do in such a situation?

EDIT: Native app.

Answer 1

It's less design and more branding. When writing an iOS app, you want to use the standard navigation bar and tab bar, but with your own brand's coloring. Sizes shouldn't change, gradients need to pop-out or in with the same direction, and elements should be rounded to almost the same degree.

Answer 2

One thing to consider is the type of app you are making. Is it web or native? I've seen quite a few arguments for NOT trying to make web apps look and act natively. If you are going native follow the UI guidelines for the platform, but dont be too concerned about making it look exactly the same as every other app. I think having your own app style can really enhance an app as long as it isn't too unfamiliar and the interactions still make sense.

It is one thing to change the layout that is assigned with interface guidelines and that people are used to, its the other to make a reskin or different styleing.

Take a look at http://www.foodspotting.com/ for example. They have apps for every phone, and on every kind of phone it does the same thing but in a different way. I think its a very nice example.
