Wondershare MobileGo for Android links your mobile phone to your Windows PC via Wi-Fi for super-easy uploading, downloading, backups, apps management, and more. It's a two-part system, with a free Android app on your phone or tablet and premium software on your Windows PC. The Android app includes a speed-up feature that frees up memory and closes unneeded apps. The Windows program does much more, like installing apps, sending SMS, finding duplicate contacts, transferring files and contacts, importing and converting music and other media files (including iTunes playlists), and one-click backup of all or some of your phone's data and records to your PC.
