I use this (in conjunction w/other tracking apps). Synthetic Void uses this. This is probably the best apptracker available. Also, with appshopper pulled from the store, some might be looking for a replacement, so here ya go: App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
Looks like the iphone version is free as well. I've gone ahead and picked up the ipad version for later.
Be careful. You might end up checking Appzapp more than actually playing the apps you pick up using it.
Free again. Looks like the Pro version of the iPhone app is free as well, this time around: App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
Used to have this on my iPod Touch. I find these apps make me download a lot more crappy stuff, with just the odd hidden gem. Still, with no AppShopper I might as well pick up the iPad version.
