ClockworkMod has announced its Carbon App for Android but its not any Twitter app which was rumored earlier. Actually its cloud based backup app which allows you to backup and restore application that allowing the user to upload said apps to the cloud, PC, or the device’s on-board storage.
Currently with ClockworkMod Carbon you can backup data to Google Drive or your SD card but Koushik also plans to add support for Dropbox in the final release.
The app requires your device to be rooted and this beta will only be available for a week, so try it now if you wish to.
