A shortcut for building real-time sync

Device Sync helps you accelerate and simplify app development. It's especially helpful for apps that must continue to function when disconnected, or apps that offer real-time collaboration. Device Sync cuts down the amount of code you need to write and maintain, streamlines application architecture, and takes care of complexities such as error handling with ease.
