Got an app in the App Store? Tracking its sales and trending data through iTunes Connect? Wanna track same if you're not near a computer?
Apple says it's got you covered. iTunes Connect Mobile lets your iPhone or iPod Touch access daily and weekly sales data related to updates, paid, and free apps, as well as In-App purchases.
While the current version has its share of online detractors (a common complaint amongst customer ratings appears to be the lack of revenue), but the app itself is free, so what have you got to lose?
