Opto 22 offers two types of mobile apps for use in automation:

• Diagnostic and commissioning apps for Opto 22 SNAP I/O and SNAP PAC Systems: Opto iPAC and Opto aPAC.
• Monitoring and controlling apps for almost any automation system or equipment from any manufacturer: groov View for iOS and groov View for Android.

This technical note compares these two types of apps and describes the best ways to use each.
