MP Install is used by designers and installers of business music systems to configure and control QSC MP-M40 or MP-M80 music and paging mixers. These mixers, offering unprecedented capabilities combined with ease of configuration and operation are intended for retail and hospitality applications in which paging messages and high-quality audio from various sources is routed to multiple zones. Live mixing functions are also supported for applications requiring reinforcement of entertainment, presentations or conferences. MP Install provides the system designer and installer an attractive graphic environment and intuitive workflow to configure and tune the system. A Setup Wizard helps the installer keep track of tasks and easily navigate the MP-M. Onboard Intrinsic Correction™ (factory FIR/IIR presets) for QSC loudspeakers help maximize the performance and value of the system.

Verdict
The clearest difference is rating: MP Install at 5.0 against ArrayCalc Viewer's 4.1. MP Install also leads on iOS requirement (12.4 vs 16). ArrayCalc Viewer's advantage is update cadence (every 4 months vs every 10 months) and ratings volume (8 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
