SwitchMe is a new application that is slightly similar to a Boot Manager app recently discovered. In the concept, they are similar. However, SwitchMe does not allow booting into different ROMs like the Boot Manager app. On the plus side—SwitchMe is easier to navigate.
The app enables its users to create a seamless and smooth installation in the current ROM without having to go through tweaks and settings. Moreover, the app has been found to do good for battery optimization while letting its users switch through different profiles.
Here are other things you can do with the app, as discussed by the developer, FAHRBOT Utilities:
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.
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 in without games or 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.
