Your choice of development tools and platforms can have a huge impact on the capabilities and time to market of your applications. We always look for the most productive and powerful development tools. Here are some of the tools we’ve found to be specially effective:
Native Objective C and CocoaTouch using XCode: If you want maximum speed, power, and control there is no better way that to use the same tools that Apple has used to build iOS.
Appcelerator Titanium provides a very nice balance of native power and developer productivity. Even thought the applications use native iOS controls, they are written in Javascript, making apps easier to maintain and allowing your team to leverage existing knowledge experience.
On the server side, we have extensive experience using Ruby on Rails to build scalable and mission critical applications and web services. For mobile web applications, we recommend JQuery and JQTouch to combine a native iOS look and feel with the advantage of frictionless deployment and updates of your mobile app.
