Do you have any references for this theory? If true it would influence my pricing strategy for my own apps. I have seen more sales at $2.99 than $4.99 but I haven't tried anything in between.
I wish I did but it's from a bunch of different posts. I wish it was easier to A / B test in the store but the daily traffic is so unpredictable and unmeasurable. I guess it could be tested on a landing page before hitting the iTunes store, even if you have to lie about the price.
