Why your ad agency likes mobile apps…why that might not deliver the best ROI for you

ndustry awards tell you a lot about a business. In recent years, the trends at Cannes Lions – the biggest date in the advertising world’s calendar – show a growing appetite from ad agencies for mobile campaigns.

Often you need to store personalized information for each user of your application. For example, your application may require users to logon to a secure server for authentication. In this case, the user needs to supply his credentials, such as a login name and a password. The first time the user uses your application this information will be entered by the user, but subsequently it would be useful for your application to “remember” this information somewhere so that it can save the user the trouble of entering the same information every time he uses your application.
