As you may have noticed (a few years ago!), mobile technology is taking over the world. Not just for the younger generation either. Smartphones and tablets are replacing desktop and laptop computers as the leading source of information, and entertainment.
Because of this, application & mobile application development is an important way to achieve the most complex or simple of goals.
Mobile application development can be used to:
Really, that's just the tip of the iceberg. Web application & mobile application development are two very different services that are often provided by the same developer.
A web application is typically designed for larger programs and needs a larger device (such as a laptop or desktop computer) to operate, but it can do more and is more powerful.
A mobile application is designed for smaller screens, and is compact enough to run on a tablet, smartphone, or both but is not lacking in functionality. These apps can also utilize device features (such as camera, GPS, and vibrate). Mobile app development for the Android and Apple Appstores are increasing in popularity as a core market for game developers because the low price leads to high purchase volume.
First and foremost, application / mobile application design is everything! Web application and mobile application development focuses on the back end design (what the app is supposed to do) as function, while prioritizing user interface (UI) and user experience (UX) design as two of the most important elements. To put it simply, an app is only useful if it feels natural and intuitive to use. The design should focus on simplicity and ease of access, not complicated and complex.
Secondly, web application and mobile application development should be scalable... meaning they should be designed to accommodate high volume usage. They should grow with you, without crashing. Of course an application & mobile application development specialist will offer support through versioning but if your app crashes too much or has too many bugs then it will create a bad experience that most users won't be willing to overlook in a saturated industry.
