I have 366 apps listed in iTunes. I'm not bragging. I probably use about 25 regularly, and probably only have 100-200 actually installed on my phone or my ipad. Is there a way to detect which apps are NOT installed on my iPhone or iPad? Since there's a different set installed on both, I don't want to lose something in the ipad just because I don't see it on my phone. I thought about deleting all the apps from iTunes, re-syncing the phone and Pad, and hoping just those apps come back into iTunes (from the devices), but I am a little worried that might just wipe out the apps on the devices. Any suggestions?
