Did some research to determine how the day of the week effects downloads: http://www.gamasutra.com/blogs/WilliamVolk/20110418/7458/Daily_iPhone_App_Sales_Trends.php May be useful if you need to see what the effects of a change in app description or other effort means.
The study was done in January though...what about Summer and Christmas seasons, when internet behavior/gaming is different?
Who makes a graph like that? Put the days of the week under the corresponding bars; not off to the side in a key. Other than that, the trend appears close to my own findings. I eat up all the sales data I can get my hands on so thanks for this.
Intersting, my experience is a bit different. Monday is second lowest of the week. Tuesday is a little higher, wednesday a little higher, thursday back down a little (about the same as tuesday), friday is the lowest of the week, then saturday and sunday are the highest (prettty much tied with each other). This is from averaging my last two months sales. I'm sure there are a variety of factors that effect these numbers (time of year, type of game etc). Anyway, still interesting to try getting a little more insight into people's spending habits.
