One of the principles of Agile development is to make a regular releases of the product: "Release your software to your end customers as often as you can without inconveniencing them." Why is it necessary? The regular project releases would help to produce revenue earlier. Except when the product is not ready, full of bugs and new features which are not welcome y consumers (remember the "Start" button in Windows 8 story?). For mobile apps development this principle is even more important. When user searches for the application in the app store and see thousands of apps with similar functionality and even similar icons, the release date and the update frequency can be the final factor. If application was not updated during last 6 months, it can be just an abandoned application - the user thinks and he will give the favor to another one, released just few days ago. Thus, make updates regularly, do not disappoint your users!
