PI-CUBE is a new app that complements IN-CUBE app, which has been available on the APPSTORE since 2017 IN-CUBE is an innovative concept of displaying decorative materials (tiles, stone, parquet, wood...) inside a specific dedicated space via an elaborate video projectors system. The customer controls, via IN-CUBE, the display of series of materials on floor and wall using iPhone or iPad by navigating according to 4 criteria (manufacturer, name of the series, colour and size). The overall objective of PI-CUBE for IN-CUBE users and IN-CUBE teams is to offer new options and to optimise installation, maintenance and diagnostic operations on equipment in three main areas: - display via the video projectors of any image present on the iPad (modelling from 3D space creation software, images of customer or visitor, presentation of collections by manufacturers, etc.) - the client launches configuration and diagnostic tests, the results of which are sent to the IN-CUBE teams in order to optimise responsiveness and quality of service with the maximum amount of information - help IN-CUBE teams during the installation of the equipment to simply configure the various settings

Verdict
The clearest difference is update cadence: e at every 2 months against Pi's every 6 months. Pi's advantage is iOS requirement (13.0 vs 15.5). On price, ads, in-app purchases and device support there is nothing between them.
