SQL Server 2017 Standard CAL Licensing - Mac OS/ iPad

Hello,

We are currently preparing for a new SQL Server 2017 Standard for our site (Internal Site).

We are buying a Server + CAL licensing model for the SQL Server to install on our server, but we found that one of our devices is using iPad to access the database through our application.

We are buying 5 devices CAL for the SQL Server, which we are wondering if this can be used/install on an iPad.

Since we are using express edition in the past, we would like to know if the CAL will work on an iPad or other android devices.

Thanks for your help.

Best Regards,
