Many Android phones have had the ability to at least dual boot for awhile now. However, the process for a lot of them can be very complicated and run the risk of hard bricking a device and even more so are still in beta with issues to be worked out.
This is a problem that XDA Recognized Developer ftgg99 hopes to solve with his app, called SwitchMe. 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. 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.
The app can be found in the Android Market and there’s a free version for people to use, but you can also find the link in the app’s original thread where you can also find additional info about the app as well as a link to the Market app._________
