younity gives you access to all your files, from all your devices, without ever needing to "sync" your mobile devices again. younity creates a personal cloud for all your files, built from your devices. With younity, you have all your music, photos, videos and documents on all your devices - regardless of storage. All your files, from all your devices, all the time.
You don't have to log into each computer or browse them separately. You don't have to put files in special folders or flag them to be synchronized. There is no storage limit because you are streaming files from your devices, so you can have 2GB, 2TB or 2PB of files. If you want to download your files to local storage (for "offline use"), you can, but it isn't a requirement.
Just use every device the way you always have and know that you can have access to any file stored on any device you own.
younity even converts unusable file formats (e.g. WMA, OGG, etc.) to iOS-compatible formats in real-time when you stream, so you can keep your media in whatever format you like.
You can even search for files across all devices simultaneously, without having to even know which device a file is stored on.
