This document discusses mobile cross-platform development. It defines three flavors of cross-platform development: web apps using frameworks like TravelMate and Kumbaya; hybrid apps using frameworks like Wikipedia and NBC iPad; and compiled apps using frameworks like Mooniz and Shadowgun. Web apps are regular web pages loaded in a browser. Hybrid apps run HTML5/JavaScript in a native wrapper using a webview. Compiled apps compile code into native apps for each platform. The document advises choosing a cross-platform approach wisely based on factors like SDK lock-in, control, and performance.

12. Web App Flow
“Regular” web pages that are loaded
Web Browser
(Safari, Chrome etc) from a remote server or installed
locally.
Local or Remote
JS, HTML5, CSS

14. Hybrid Apps Frameworks

15. Hybrid App Flow
Similar to a Web App –
Native App
A native app runs a JS/HTML
application in a webview with a Bridge
Web API
View Bridge
for Device API access.
HTML5 / Javascript

16. Notable Hybrid Apps
Wikipedia NBC iPad Harmonious Wunderlist

17. Compiled Apps Frameworks

18. Notable Cross Compiled Apps

19. Cross Compiled App Flow
SDK Codebase
Code Generator Code in SDK language is compiled into
native applications for each platform.

bring you life, the false Grail
will take it from you.”
