Application Concept
* Solve a problem

• Keep it simple - one solution per app, please.
• Create for a mobile device, not for a desktop
• Think about how people use the iphone
• Most apps are used for only a couple of minutes at a time

Application Definition Statement

• Single best way to focus your app

(How it's different, what it does, and who it's for)

• Easy to use finger paining for the kids
• Beautiful, easy to use budget tracking for the home
• A fun eas to use flatulence noise make for immature adults <- THE DON'T

Know the Rules

• iPhone Human Interface Guidelines
• Use apple-designed widgets
• Don't break common paradigms - certain buttons do certain things - DON'T Change them!

Break the Rules

• Some controls you need to make yourself
• Try to find a real-world analog
• Design to impress Apple (get on the TV commercials)
  Example is a gas gauge for budgeting or pillbox

The finger is not the mouse

• Mouse cursor has a resolution of 1x1 pixel
• The Finger on iPhone up to 55x55 pixels

User-centered design

Paper prototyping

• Forces you to think finger-sized" You can't sketch tiny"
• Easy to hand off final sketches to developer
• Think about the app as a series of screens

Coding

• Objective C best place to start

Getting Registered

• developer.apple.com/iphone
• Register as company or individual
• $99/year

Uploading your app

• Developer Account ($99/yr - pays for itself with minimally successful app)
• Screenshots - hold top button and home button
• Description - enough marketing text to pull someone in.
• Small Icon 57x57 - 99designs.com
• Large Icon (512x512) - for TV or Magazine Ad (design large one first then scale down.)

Selling Your App

• You set price
• Apple takes 30% - apple handles puchase
• Free Apps cost you nothing (other than the Developer license)

Review Process

• Current wait is approximately 2 weeks
• Horror stories you hear are the exception
• Your app will be rejected, and that's a good thing
