There’s a reason why the saying “there’s an app for that” came about. Some believe that eventually, the reliance on apps will become so prevalent that businesses will almost have to invest in an app. Now that search engines can crawl, index, and even stream content from apps, there’s even concern that traditional websites will play less of a role in the future – possibly disappearing completely.
