Most smartphone and tablet owners who download apps will still not pay for them. Pew Research Centre questioned 2,260 adults aged 18 and over and it found that 46 percent of those that have downloaded apps to a smartphone or tablet have paid for one or more of them.

This is the same as it was in during a similar survey in 2010 which means that people are still not confident to shell out money for Apps. Among those who decided to get the wallet out, 52 percent said the most they have ever spent is $5. Still, there are some buyers willing to pay more, with 17 percent saying they’ve spent $20 or more for a single app. Owners of tablets are more likely to pay for an app than those downloading to a smartphone. Furthermore, those with tablets are more likely to spend a greater amount on an app than those who buy an app for use on a smartphone.

The figures will make many developers wonder why they are in the business at all if it can't make them cash.
