9. • One‐Time Storefront Purchase
• Subscription APIs
• In‐App Purchase / AVB
• In‐App Advertisements

10. • Good Industry Patterns:
– Hardware Innovation
– Open, well‐supported SDKs and APIs
– Devices that consistently implement APIs
– Multiple billing models
– Low‐friction store submissions
– Balancing Quality and Quantity in the Stores

11. • Qualcomm:
– $3+ Billion in developer revenue
– Consistent SDK and APIs
– Consistently implemented on devices
– Single submission to multiple storefronts
– Good developer support
– Good Monetization strategy
• 1 time billing, subscriptions, demos, IAP

12. • Carefully select development tools
• Carefully select Reference and Target Devices
• Effectively use the tools available to you
• Learn from past projects & experienced partners
• Apply a good QA strategy
• Plan a monetization strategy from the start

13. Development
Android
iOS
WP7

14. • Native SDKs & APIs
• Hybrid Native / Webkit
• HTML5
• “Rapid” and “Universal” Runtimes

Always check the licenses first

18. • Consider using OpenGL.
• Use the SD Card ‐ it’s faster.
• Use the platform tools ‐‐ XCode
Memory Analyzer, Eclipse MAT, etc.
• Use NDK if you hit Android memory or
performance problems.
• Design separately for tablet vs phone.

19. • Don't try to make iOS‐native UI
widgets on Android, or vice‐versa.
• When converting menu‐driven
applications…
– Convert the business logic line for line
– But create the display logic appropriately
for the target platform.

20. • Design and develop to provide the
best of each platforms.
• Don’t go for lowest‐common‐
denominator.
• … but ensure business logic is
consistently implemented across
platforms.

21. • “Beautifully Different”
• For Apps, start fresh with your design.
Follow Metro Guidelines.
• Find an experienced partner or go to
training.
• If converting from an existing app, try
to start from an Android codebase.

22. MS provides some good info...

23. • CPU processing
• Tombstoning
• Panorama vs Pivots
• Use Live Tiles
• Smoothstreaming only
• No Flash

24. QA

25. • Create Test Plans in conjunction with
Design and Development.
• Efficiently address fragmentation.
• Always test under multiple network
conditions.
• Include automated tools where they
make sense.

26. • Don’t use an API unless there is a
clear use case benefitting the user.
• Be mindful of iOS monetization rules.
• Do not use UDIDs. Use UUIDs.
• Use the iOS configuration.
