I see a few "uninstall apps" on the market and I am wondering why there are such applications. Uninstalling an app from the phone is not that complicated and it is quite fast. Maybe my question is silly but I am very new to Android. I know that Windows for example does not uninstall programs properly, and one needs often a third party program to really make a clean uninstall. Is that the same with Android, or do these apps just make it faster to uninstall an app (with the same result that one will get with a "uninstall" process through the apps manager)?
