91 PC Suite for Android is a program for managing data on Android smartphones. It works the same way as iTunes works with iOS devices. Once you connect your smartphone to your computer, you can manage your contacts and SMS messages, work with your calendar and tasks, read Email messages stored on your smartphone, view your browser bookmarks, etc.
The "Media" tab allows you to download music, videos, photos from your phone and to your phone. You can also set new themes and take screenshots from the device screen. If you want to back up important data, you need to go to the "System" tab, where you will find not only the tools for backup, but also the phone setup tools.
Everything is quite simple in the program despite the fact that the interface is presented in English. The phone is only connected via USB cable, and the software does not require much computer resources.
