Maybe it’s because they’re managing all of their many assets using the latest apps, or they’re too busy booking first-class tickets to their next sun-soaked vacation, but wealthy smartphone users seem to simply have no time to string together 140 characters and hit “tweet”.

A new survey from the Luxury Institute looks at how wealthy smartphone users in the US use their devices. Those interviewed at to be earning at least $150,000 a year, and had an average net worth of $2.8 million.

Of those interviewed, only 62 percent actually have a smartphone. And in this group, 45 percent have an iPhone, 35 percent have an Android, and 25 percent prefer BlackBerry.

The majority (80 percent) of wealthy smartphone users do have apps installed, but they’re not using their phones for gaming or social media. The most popular categories of apps included weather (63 percent), news (51 percent), travel (42 percent), business/finance (39 percent) and sports (34 percent).

Still, breaking the mold as it so often does, Facebook is actually the most popular app used by wealthy smartphone owners, and it’s used more frequently than any other. When they do have time for gaming, this elite group likes to play Angry Birds and Words With Friends.

And where’s Twitter on this list? Nowhere. Twitter doesn’t come close to Facebook or even weather apps in terms of use or popularity.

The wealthy are apparently concerned with keeping their smartphones distraction-free, as they cite a lack of interest (49 percent) and a desire to keep their phones simple (32 percent) as the main reasons for not bothering with Twitter and other apps popular with those of us a little lower on the pay scale.

Reuters spoke with Milton Pedraza, CEO of The Luxury Institute, to get at why wealthier – and typically older – smartphone users aren’t tweeting:

“As you get older and have family and significant others, aging parents, and a lot more assets and investments, you’re going to need apps for far more relevant things than playing games and chatting with your peers.”
