Agenda
• Application publishing
• Perf & Polish: Making your app work properly as well as look pretty
• Monetization: Money making possibilities

3. 3
Perf & polish
• Final touches to the app: make it perfect with good performance,
and polish the outlook and behavior
• Can take surprisingly long time - developer possibly not the best
for this task
• The application itself is often done ok prior to this phase, provided
proper development procedures are followed
• Testing, e.g. TDD and CI
• Development guidelines followed

4. 4
Performance
• Perceived efficiency is often what matters the most
• If it is usable - performance is ok
• Points of interest:
•
•
•
•
Startup time
Memory cap - 150MB on WP8
UI thread vs. background tasks
Platform interactions: e.g. tombstoning
• Tools:
•
•
•
•
Debugger
Code Analysis, Code Metrics
Performance Analysis
Simulation Dashboard

5. 5
Polish phase
• Making the app look pretty and meet store requirements
• Can not typically be strictly separated from the perf phase
• Create artwork for Tiles
Tile Size
Flip and Cycle Images
Iconic Images

N/A
• Support for multiple resolutions
• Make supported sure orientations, themes etc. can be used
• Globalization… more 

6. 6
Globalization
• Globalization = Internationalization &
Localization
• Language, currency, symbols..
• There are some caveats in the language
selection
• Obviously should be done from the beginning even if initially only a single language will be
supported
• Language does not only apply to the app!
• Not a bad idea to use a native translator Google/Bing translations work only so far..

Monetization
• Want to make money? Now or later? DOWNLOADS
• Best way to make money is to have money and use it
• Next best is to make the store page appealing  downloads
• Third best is to make a great app
• Free apps can be made commercial, not the other way around
• Try-and-buy can be used to entice users
• Ads are a possibility, PPC not great, forget if not a killer app
• In-App-Purchase has most potential

10. 10
Ads & IAP

11. 11
Get people to download
• Good screenshots, description, etc.
• Stand out from the crowd
• Market the app!
• Get reviews

12. 12
User experience
• Do you know what people want? How about a UE expert? For all
local market place audiences?
• Test with real users
• Beta testing, invite your 10,000 best friends to test for 90 days
• Application Analysis, also during beta testing

13. 13
End user experiences

14. 14
Analytics overview
• Information about your app's usage
• Identify problems
• Make intelligent decisions about updates, fixes,
additions
• Not merely how many apps downloaded and if
they've crashed
• How about knowing that 30% of users don't
play beyond level 4, of those who do 20%
purchase the app between levels 9 and 10? Or
that IAP starts slowly, peeks after 2 weeks in
Europe, 3 weeks in Australia, and 1½ weeks in
USA – and there is no significant difference
between registered and unregistered users?
