For ppl who like to install free apps frequently from Android Market to try out, very often you find your smart-phone out of phone memory and have to uninstall some of them to make space for new free app. Then one fine day you vaguely remember you have intalled certain free app before and you are keen to know the full name but you just cannot remember.This app serves that purpose. It will log all app install and uninstall package name and date. Then you can do a search based on a date range etc to see what are the apps you have installed previously.To configure, tap Start to start the Package Tracker Service. To search, set a date range, select package type, order by some criteria and then tap Search.
