According to BGR Nearly two-thirds of consumers in the United States have spent money on mobile applications on at least one occasion according to a survey conducted by ABI Research.
I have to admit I really have not paid for many apps in my life. I do have a couple that I thought were worth the money.
Here are the 4 apps I paid money for
Office suite Professional 6 - Really functional, easier than Google Apps to use for documents. Bit slow to load if you trying to access shared docs, otherwise really worth $9.99
Calengoo- Only calendar program I need to use. Works really well on on my Kindle Fire. Totally worth the $5.99.
Tune In Radio Pro - Listen to any radio station worldwide. Great stuff and worth the $.99 to be able to record.
Monopoly- Fun game, and plays just like the board game. Good diversion every once in a while. While I don't have that much time to play it, it was still worth $2.49
