Icons are too damn important
21. As we’ve previously mentioned, the icon gives users a first impression of your application : if it looks unattractive or ill-conceived, the application will not be taken seriously. You can take a look at what the App Store has to offer in your category of applications and compare your icon with other icons out there. A good way to evaluate how well your icon looks is to place it on the screen among others.
Manner and matter
22. When developing applications you should always consider that the form must always follow the functionality. There is always an infinite number of embodiments of the problem in terms of appearance and atmosphere, but it is of first necessity to be clear about the purpose of the application before you start to work on it’s appearance and the definition of the target audience. Naturally, different audiences prefer different styles - for example , applications for business should not be enforced in a cartoon style.
Add functionality the smart way
23. Since the application evolves over time, always try to add features without adding complexity - this process is known as "layering functionality”. Start with a well-defined frame structure, information architecture and interaction schemes and be consistent - this will add more features without changing the concept of the application.
Design the icons carefully
24. Remember that an icon is the main positioning element - it should not mirror your application functionality but be suggestive enough of what the app does. Though, mind that it’s color scheme and shapes should be similar to the design of your app. The user should not feel a dissonance between the appearance of icons and the application itself.
Good design can be universal
25. Quality design can be adapted perfectly to different screen dimensions - just think of such websites and apps such as Google, Facebook and Twitter. They have been adapted for different forms or versions of applications for all platforms. Though smaller versions usually have a more conventional structure, but for the most part have the same look and feel.
26. Visual thinking often helps to improve the idea. Just use a pen and paper, Photoshop or any other drawing tools. If you have a working prototype of your app of the device, you can get valuable testing cheap - just buy a cup of coffee to a friend in exchange for a 10 -minute informal usability testing.
Users expect a specific behaviour
27. Typically, users expect that the program will function and look a certain way. For example, do not use the "pinch" gesture for any functions except for zoom and collapse of the image or other objects because it will only confuse users. Though you can still feel free to choose the colour schemes to your liking as it would be too boring if all applications copy the standard Apple palette.
Less is more
28. It could sound pretty obvious but it is better to leave the application simple and avoid layering functions. Avoid stacking large amounts of information on a small screen because it is likely to confuse your users as to the primary functions of the app.
Set goals within your app
29. Always try to develop your applications considering the target actions that you want your users to produce. When you have an idea of what your users must do with your app makes planning the UI/UX much easier. All you would have to do is just help him achieve the goal that you’ve set within your app. Typically, applications are developed based on a common technical concept where the user interface is built around the user’s needs.
Pick only one stylistic theme
30. Most quality applications have a single stylistic theme which in turn affects the design decisions and gives the app a sense of wholeness. This visual theme should always correspond to the main features of the application. A counter example when the theme is not entirely consistent with the function is the use of "stitched leather” in the Find my friends app by Apple Inc in iOS 6.
