SynchronZu

SynchronZu migration assistant will help you seamlessly back up your device's
address book and calendar to your device's SD card storage, email account, Google Drive or Microsoft SkyDrive as well as migrate address book and calendar from your Android to Windows Phone 8, Windows 8 or BlackBerry 10 device.

Most importantly, it's all done wirelessly, so no need to connect your phone to your PC, install drivers,
run some program on your PC, nothing like that !

Use this application to back up your address book and calendar to email, local SD card storage or secure Google Drive or Microsoft SkyDrive (you'd need Google ID or MS Live ID for that, it's free) and
subsequently restoring it back onto your Android device or transferring via Bluetooth or e-mail directly to your
Windows Phone 8, Windows 8 or BlackBerry 10 device. In case of migration please make sure you install SynchronZu application on your Windows Phone 8, Windows 8 or BlackBerry 10
device as well (from Windows Phone Store, Windows Store or BlackBerry App World correspondingly) and follow the instructions.
NOTE: due to MS SkyDrive limitations only 1000 contacts can be transferred if selecting an option of transferring via MS SkyDrive.
