To be a native mobile app, or not to be a native mobile app, that is a good question.
Over the past decade, native mobile apps (downloaded in an app store) gained popularity, and then lost popularity with the more prevalent use of responsive web designs. The success of native responsive web design increased popularity as it only requires one development track. Choosing to create a native mobile app, it can mean creating multiple apps (os or tablet/mobile) and exponentially increase the development track without a clear return on the investment.
