This application is one of the very useful app I ever made for my own purpose.
This app just stores the Market information for a particular application in to the SD card of the phone in a Database.
So, when ever you install any application in the phone, your SD card remembers it. So, when you do a factory rest of the phone, just by installing the 'AppHistory' you can have market links to all of the apps you had.
I am going to update the application with more information like,
1. date of installation
2. Number of times you installed / un installed
3. Share the application to your firends via Twitter / Facebook / SMS / Email.
4. Share the application list [as a DB file] to your firends, etc very soon.
Thats it.. Enjoy with the applicaiton.
