There is no doubt that mobile app usage is growing. In fact, U.S. consumers spend 35 percent more time with mobile apps than they did last year, at 127 minutes per day. That’s more than two hours daily. Compared to traditional desktop web usage, which sits at 70 minutes daily, it’s pretty clear that mobile apps are absolutely spanking PCs. And San Francisco-based mobile analytics firm Flurry thinks it may do the same for TV.

TV viewing in the U.S. still beats out mobile usage, if the 2010-2011 figures from the U.S. Bureau of Labor Statistics holds up. According to this data, the average U.S. consumer indulges in 168 minutes of television daily.

So let’s do the math: 127 and 70 come out to 197 minutes per day (for mobile apps and PC). If the 168 minutes of TV viewing held up this year, that would be 168 minutes to throw on the pile. All together, that’s slightly more than 6 hours. If you work 8 hours per day and sleep 8 hours per day, that doesn’t leave a whole lot for other things — like eating, dating or anything else that resembles a life.

Granted plenty of people multitask, so these numbers alone don’t paint the whole picture, but it does underscore something pretty striking — mobile app usage is already undercutting PC use, so for it to continue to grow, it only makes sense that TV viewing, i.e., the other primary entertainment activity, will get hosed too.

Says Flurry CEO Simon Khalaf, “We ultimately expect apps on tablets and smartphones to challenge broadcast television as the dominant channel for media consumption.”

So what are these apps that everyone’s spending their time on? The firm’s annual report, which took a look at the trends in app categories, revealed the following:

  • Last year, games accounted for 50 percent of time spent in mobile apps. It’s still leading the way, but at 43 percent, it decreased slightly.
  • Social networking made up 30 percent in 2011, but now comes in at 26 percent.
  • Entertainment apps and utilities stole some thunder from social networking and games, as they’ve both gained marketshare.
