As mentioned a few posts ago, Apple’s iTunes sales reporting tools are a joke.
In walks AppFigures.com. This site provides exactly the type of data I would expect Apple to provide. It automagically grabs your iTunes sales reports every day, then uses the data to generate Google analytics style charts and graphs. Before using this site I only had a vague idea of how many apps I’d sold.
If you’re an iPhone developer I highly recommend you drop everything and start using this app.
