your data, your devices.

Automatically sync your existing SQL Server data to all your mobile devices.

Zumero for SQL Server (ZSS) v3.3.0

ZSS can be hosted on your own servers next to your existing SQL Server database, or installed on a cloud platform such as Microsoft Azure.

Zumero requires no changes to your existing data; it works alongside your SQL databases and applications, keeping changes up-to-date (in both directions) between SQL Server and mobile devices.

Your applications need not know or care that synchronization is occurring, nor do your mobile apps need to worry about staying up-to-date with the backend. ZSS takes care of the details.

If you're building an application with a new SQL Server database, then you may want to host your ZSS Server on Azure
