The number of apps available for mobile devices has increased exponentially over the last few years. Consider that the first apps came out in 2008, and today there are almost 2 million apps available across all platforms.
An app is a slang term for an application that can be used on a computer or smartphone, and numerous types of apps cover a variety of interests, from games to banking to sports. The HVACR industry has been quick to jump on the app bandwagon as well, with many manufacturers and associations rapidly introducing apps geared toward contractors.
