Really fantastic article, complete with graphs and solid numbers, as well as detailed explanations of those figures.
The underlying theme in all app pricing advice I've seen is that if you're not in the top 100, the actual price of your app matters very little. That is completely borne out here, with price increases resulting in more revenue and about the same rate of units sold.
It’s bizarre, but I’ve had this experience as well. Last October, I started raising the price of my app by $1 every week or two. The total number of purchases per week varied very little, so I ended up leaving the price at $9.99 (the highest I tried).
I experience something different. From $0.99 up to $9.99, no matter what price I set, my daily income remained essentially the same. Before you ask, the amount was greater than $0.
