Do you pay for any of the apps you use on your smartphone or tablet? Or are you one of those (many) people who take only what they can get for free?

Business executives – like the general public, not surprisingly – vary in their willingness to open up their wallets (or tap their credit cards) for the privilege of downloading apps.

As part of a special "App Report" coming Friday in the Jan. 10 print edition of the Puget Sound Business Journal (a sister publication of TechFlash), we surveyed several executives to see how they use their mobile devices – for both business and personal purposes.

This week we're running their answers to four questions. We've already reported on the apps they use most often for business purposes and for day-to-day living. Today we focus on their willingness to spend.

The group we surveyed includes executives drawn from responses to an email blast we sent to dozens of people. In case you notice the lack of women on the list: We sought out a number of women, and unfortunately none participated.

The group:

Spencer Rascoff, CEO of Seattle-based online real estate site Zillow, uses the Apple iPhone 4S on AT&T and the Android-based Samsung Galaxy Nexus phone on Verizon.

Greg Rankich, CEO of Redmond-based IT and business services firm Xtreme Consulting Group, uses the iPhone 4G.

Blake Cahill, president of Seattle-based social media ad agency Banyan Branch, uses an iPhone and iPad.

Pete Shimer, managing partner of the Seattle office of audit, financial advisory, tax and consulting firm Deloitte, uses an iPhone 4 and an Amazon Kindle.

Steve Jones, CEO and partner of Bellevue-based IT consultant firm Explore Consulting, uses an iPhone 4s.

Jim Copacino, co-founder and creative director of Seattle-based ad agency Copacino+Fujikado, uses an iPhone and iPad.

Marc Williams, president of Seattle-based ad agency Williams Helde Marketing Communications, uses an iPad2 and iPhone4.

Dan Voetmann, owner and CEO of Mountlake Terrace-based ad agency Destination Marketing, uses a Motorola RAZR phone and an iPad.

Today's question: What's the most money you'll pay for an app?

Rascoff: $1.99

Rankich: $4.99

Cahill: Free

Shimer: $0

Jones: No limit if the value's there.

Copacino: No limit. It depends on the utility/value.

Williams: $10

Voetmann: It’s in direct relation to its value. I’ve paid 20/30 bucks for productivity tools, but rarely pay much for foolin’ around stuff. There are so many good options for free.
