Geek Posted April 27, 2011 Posted April 27, 2011 <div class="KonaBody"><p><img src="http://osxdaily.com/wp-content/uploads/2011/04/estimate-ios-app-sales.gif" alt="Estimate iOS App Store Download and Sales Numbers" title="estimate-ios-app-sales" width="446" height="146" class="aligncenter size-full wp-image-15332" /></p> <p>Getting specific information about iTunes & iOS App Store downloads is notoriously difficult, very few developers are candid enough to share download counts and the majority of developers guard download data for competitive reasons. If you’re curious how well a specific app in the iOS iTunes Store is selling, try using this quick and dirty formula to get a rough estimate of sales numbers:</p> <p><strong>Number of Ratings * 30 = Sales Estimate</strong></p> <p>This unscientific formula <a href="http://blog.riverofnewsapp.com/2011/04/how-to-estimate-sales-of-any-app.html">comes from</a> the developer of River of News, a Google Reader app for iPad, who confirms the formula is reasonably accurate:</p> <blockquote><p>I found several sources independently say that about 1 in 30 buyers of a paid app will rate it in the store. I now have two apps in the store and that ratio has held up remarkably well.</p></blockquote> <p>I ran the formula on Angry Birds, and came up with six trillion quadrillion gazillion infinitiy downloads, which sounds about accurate. So the next time you start <a href="http://osxdaily.com/2010/09/07/iphone-development-costs/">pouring money into iPhone app development</a>, take a look at some of the apps out there and run the formula, it’s not perfect but it’s better than nothing.</p> <p><strong>Update:</strong> fixed the link to the developer site.</p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/HkOhLGqfJ0RqTG8EUjyVyAXkUJw/0/da"><img src="http://feedads.g.doubleclick.net/~a/HkOhLGqfJ0RqTG8EUjyVyAXkUJw/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/HkOhLGqfJ0RqTG8EUjyVyAXkUJw/1/da"><img src="http://feedads.g.doubleclick.net/~a/HkOhLGqfJ0RqTG8EUjyVyAXkUJw/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=JGP-fNLbf1g:mgeeRnZePk0:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=JGP-fNLbf1g:mgeeRnZePk0:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=JGP-fNLbf1g:mgeeRnZePk0:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=JGP-fNLbf1g:mgeeRnZePk0:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=JGP-fNLbf1g:mgeeRnZePk0:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=JGP-fNLbf1g:mgeeRnZePk0:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=JGP-fNLbf1g:mgeeRnZePk0:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/JGP-fNLbf1g" height="1" width="1"/> View the full article
