About this presentation
1.Work with a designer
• Default UI components look dated
• Mobile design has evolved
• Use other apps to keep in touch
• If this is not your cup of tea, find a designer!
• But... know the basic tools

5.Stay away from
WebViews
• Objective-C
• PhoneGap
• Appcelerator Titanium
• Mobile webpage
• ...
Options
• Efficient multi-platform
• Existing language skills
but ...
• Performance of webviews is terrible
• Lowest Common Denominator
Cross-Platform
• Native “feel”
• All features
• Always cutting edge of platform
Native
• Currently two relevant platforms
• Each platform has unique qualities
• If possible, always build native
• Avoid webviews!
Our opinion
6.Apple’s word is law
• App Store Review Guidelines are final, but...
• ... not all rules are enforced as written
• ... rules change over time
• ... reviewers make mistakes
• ... reviewers test as end-users
The rules
• Read the rules
• Some ‘common wisdom’ is outdated
• Don’t try to outsmart Apple
• Don’t touch Apple’s 30%.
• Roll with the punches
Solutions
7.Never commit to a
launch date
• Currently 1 week, but ...
• ... can take longer
• ... can take shorter
• ... only when you are approved
The review process
• Always plan for delayed approval
• Publish a launch date after approval
• Apps for events are tricky
• Expedited reviews
• Contacts inside Apple
Solutions
8.Track your app

9.Your app will (probably)
not make any money
• A peak and then nothing
• Invisible in the mass of apps
• Building a good app is a must, but not enough
• Gimmicks hardly attract attention anymore
• Mobile ads are no goldmine
• Making money in The Netherlands is hard
• NL is 60/40 not 70/30
A typical app
• Any attention helps: press, advertising, App Store visibility, related channels
• Established brands are powerful
• Freemium models work, payed apps are harder
• Jailbreaked devices and cracked apps are often a small problem
• Validate In App Purchases
Solutions
10.Go for it!
• Mobile is here to stay
• You will have a job
• It’s very visible
• People will understand what you’re talking about
• Still much to be discovered
