A mobile application is a software application that works on a specific mobile device's operating system and is downloaded to the device to perform a specific set of functions. Apps can also be device-specific such as iPhone and iPad apps.
Every mobile project presents unique challenges and considerations, but regardless of your circumstances, deciding whether to create a mobile app or a mobile website does not have to be difficult. Define the purpose of your application and prioritize all of your business and marketing considerations first. Then determine the solution that will best address those needs now and into the future.
