Ask any interactive agency nowadays what their clients are asking for when they need a mobile experience — the answer will inevitably be "an iPhone and/or an iPad app." Native Apple apps are a hot commodity, and in today’s mobile application ecosystem, mobile web apps are not sexy. In fact, many people don’t even realize they are even an option. In certain cases, an iPhone/iPad app will be the right solution for their needs.
However, there are some situations where it may become a short-term win, but eventually a long-term loss. Mobile web apps offer a good number of advantages over native apps; and though they face some design, development and deployment challenges, they are a powerful cross platform, scalable and affordable solution.
