Hello,
Am looking into developing an iPhone native app using Titanium Developer - http://www.appcelerator.com/
Since this is still in beta, am wondering if there are any better options and/or if its a good idea using such software to develop native apps (which are not games; not graphic intensive)
Thank you for your time.
The similar and more mature PhoneGap framework has been used in a number of iPhone apps and Apple only seems to object if the application autoupdates.
That being said, I wouldn't recommend using web frameworks unless your application is really simple--you will get a much better experience from a native application (on both Android and iPhone)
If you don't want to wait, you can do what a lot of us did: develop apps in Cocoa Touch. It works perfectly well for games as well as non-graphic intensive apps.
My company uses Titanium and it's working fine so far. It's also a pleasure to develop iPhone app using javascript and co. I'd recomend you give it a try, it's really simple to set up and start coding.
