Neil Perlin spent the afternoon heading this hands-on session that showed how to create mobile apps with an web-based program called ViziApps.This program combines a browser-based development environment with its own device-based app that allows you to see, run, and test your app on your device.
Even the smallest mobile apps can cost thousands of dollars to have developed and can take weeks to produce, test, and release. The average time to market is 12 weeks.
ViziApps provides a GUI model with an emphasis on design, not coding. It's one of a larer class of GUI app development tools. ViziApps is least template-bound, most visually flexible.
Most apps require data. While you can use Google Docs (which in itself is quite powerful), you can also use ODBC, the Force.com platform, and other web services.
It's important to design for a small screen. Organize related elements on one screen and within the screen size. Create clear transitions between screens. Think of your users' physical contexts, including the number of hands they have available, the range of motions of their fingers, and their use environments, which can include noise, distractions, and light.
Whenever you make a change in the app, you want to preview it on your phone to make sure your change works and dos what you intended. This is a constant process: iterate, test, iterate, test, and so on.
