Carolina Milanesi with some interesting results from a survey of iOS and Android users. We've known for a long time that App Store customers are incredibly price sensitive, but this sentence particularly stood out for me:
In other words, great reviews, feature list, screenshots, and app description do not matter if the price is already beyond what the user perceives to be the right price for the app.
If you've not played with adjusting your pricing for a while, read this and give it another thought! Note that the survey only had 800 participants which makes the data much less useful but I still thought it was interesting.
