In-app purchase vs. paid

A couple of months ago I published some stats about the PhotoMeta in-app purchase. 

In the mean time I changed my strategy. 8 weeks ago PhotoMeta became a paid app instead of a free app with an in-app purchase. The price of the app ($2.99) is the same as the price of the former in-app purchase. So how did this work out so far?

As you can see the number of paid downloads are significantly lower than the number of in-app purchases in the last 8 weeks before the change. However, I'm going to stick with the paid app for the following reasons:

• No more 1-star reviews from users who downloaded a free app and feel mislead because an in-app purchase is required for the "full" version
• PhotoMeta is targeted at advanced amateur and professional photographers spending hundreds/thousands of dollars on gear every year. Paying $2.99 for a useful app shouldn't be a problem.
• The in-app figures are slightly distorted because they include the Christmas period
