EMS Express Mobile Software - Quantum Ultra is an application designed to provide intuitive user control of Quantum Ultra videowall processors from Apple® iOS® devices. The software combines the freedom of wireless control with an easy to use application operated with familiar finger gestures, such as tap, drag and drop, swipe, and pinch/stretch. It facilitates preset selection, window size and position, source selection, and other common operational tasks, and can work in tandem with VCS and a control system. Up to 10 users can control one or more videowalls. Separate User, Designer, and Administrator credentials define operational roles. EMS-Quantum Ultra is ideal for use with systems requiring one or more points of control through a user-friendly interface. EMS-Quantum Ultra can be used in any application that requires mobile, wireless control of a videowall for operational use. This includes corporate conference rooms, command and control centers, network operations hubs, or other applications that would benefit from intuitive control, either single-point or multi-point. A LinkLicense® upgrade for the Quantum Ultra, LinkLicense for EMS-Quantum Ultra, is required to enable communication between EMS and the processor.

Verdict
The clearest difference is update cadence: Atrius Facilities at every 4 months against EMS's every 10 months. Atrius Facilities also leads on device support (3 vs 1). EMS's advantage is iOS requirement (12.0 vs 15.0). On price, ads and in-app purchases there is nothing between them.
