1. Apples Demand from Developers: 10 Essential
Rules
Bangalore: As any good designer in App Development will tell you, great implementation of
an impressive feature is only the beginning. But for an iPhone app that has to get approved by
Apple, presentation that goes hand in hand with logic, purpose, and structure of the app is
vital.
10 principles of designing good apps that could prove handy will gain your app an entry into
the list apps approved by Apple are as follows:
1. Idea-mapping
You're not going to get anywhere until you have a clear idea for yourself of what you aim to
make, so map your ideas, and set a clear purpose for this app.
2. Ergonomics
The UI should be spotless, so the user would want to tap them. Its buttons must be such that
the user knows what they do at a glance, and most importantly, at the first time.
3. User's Needs
One might not know what one needs until one sees it on screen. Bear in mind what the user
will and will not require on each page. Less clutter makes things a lot clearer, so do not fear
white space

2. 4. Beauty
Transitions, animations and even the buttons every bit of visual feedback needs to be visually
appealing, while fitting the theme of the app. Make sure the animations serve to clarify what
the user could do with the apps.
5. Mobile = Tactile
The way the user gets to control touch is important. Make sure the control system you design
is engaging yet touch-optimized. Make defaults intelligent, and yet easy to do away with, or
easy to customize.
6. Iteration
Keep in mind to not plan too much, but keep playing with the design as much as possible and
gauge the UI's effectiveness.
It is vital to think of every possible button/element on every screen.
7. Clarity
Make clear to the user what he/she has control over. Jargons would sound impressive to a
hard-core techie, but they would lose value to one who has no idea what you mean.
8. Elegance

3. The implementation of all the above should be smooth. Not only would the user-interface be
good to look at it should also be easy-to-use. One such way to do this would be to use buttons
that are of 'tap-able' size.
9. Polish the App Icon
The icon represents your App, so make sure it shows the user what he/she can do with it.
10. Honest pricing
Although it is tempting to price the app according to the work you put into designing it, it
would be best to price it according to how often the user would turn to it. Test often with
subjects, who would give you honest, yet varied feedback.
