An Android device say e.g. Android tablet might be shared by multiple users and obviously, everyone wants a different profile/user to configure things as per there likes/dislikes. In other cases, you might need clean user profiles that provide an android environment which is totally different from another reason.
SwitchMe lets Android users switch User accounts, Profiles just like they can do it on a Windows, Mac OS X PC. SwitchMe allows users to create profiles specific to their needs. Those profiles are saved, can be loaded whenever and users can create new profiles that are on whole new installations on Android.
SwitchMe is a unique application for root users that allows you to log in and out of multiple installations of Android just as you would on a desktop computer. The technology behind SwitchMe saves all of your applications and data, protects it and stores it as a file in memory. You can then log out of an account and log into a fresh installation of Android or another account with its own unique content.
You may create as many profiles as the memory is capable of holding. Some of these may require very little free memory because they contain few apps, others will be larger as they contain many applications and lots of cache and data.
The uses for such an app are plentiful, as ftgg99 explains:
Privacy – the most obvious benefit is that you can securely share one device among multiple users, which gives you privacy and peace of mind.
Testing – if you are a developer, you can use profiles as clean sandboxes to test your applications and their interaction with the system.
Gaming – with multiple installations of Android on a single device, you can now play online MMOs as different characters.
Speed – the games your kids play slow down your tablet, but with SwitchMe you can easily create profiles without games or instant messengers.
Battery life – when the battery is low but there are important emails or documents to edit later, switch to a profile which only contains these essentials.
