Mobile apps are the hot thing these days. While they can be entertaining, educational, informational, and very helpful, we advise caution before jumping in with both feet to create an app for your business. We blogged yesterday that just because a technology exists, doesn’t mean it is necessarily useful for your particular business. The optical industry is one such business where apps for eye exams are being pushed, even though most people get an eye exam every two years, or at best, once a year. We wonder why someone would want to download an app they may not use until they get a new phone and have to do it all over again. That is not to say that tends of thousands of apps aren’t extremely wonderful programs worthy of your attention. This infographic from Nuance Communications shows how powerful the app economy has become.
