The Apple Watch has been all the news the last few weeks, and it’s unsurprising, given that smart watch sales are expected to grow from 4.6 million units last year to 28.1 million units this year. What does that have to do with real estate, you ask? Yesterday, Trulia announced they now have a version of their app for the Apple Watch, which extends the functionality of their iPhone app. If the Apple Watch is anywhere near as successful as one would predict, then this trend will only continue, with other real estate location services creating apps both for the Apple Watch and other, Android-based smart watches.
