Is the version of each device, and its version of software avaialble in the system, so we can prompt users to update, bear in mind some of the devices are on site with gangs with little IT skill, so we can track who has what device, and what version the software is at when it syncs.
The Alloy App has the version information pinned to the bottom of the menu, hope that helps
Its the version of each and every mobile device, whenever we have training sessions they get sent emails to say bring your tablet, make sure its up to date, and they never are.
Like on Mayrise we have the DEVREG table, and a screan to see what devices need updating
