Comparison between Corona, Phonegap, Titanium

Answer 1

Rhomobile Rhodes (http://rhomobile.com/products/rhodes) is very similar in approach to PhoneGap, but is the only framework with:

1. a Model View Controller pattern (as most web frameworks provide)
2. an Object Relational Manager
3. support for all popular smartphones (including Windows Phone 7)
4. a hosted development service (not just hosted build): http://rhohub.com
5. a full debugger and SDK-less emulator in the RhoStudio IDE
6. support for synchronized offline data
