Good first attempt
I use an Si Expression 3 and use 10 busses for monitors. The Visi iPad app can be frustrating because the musicians have access to the main mix and often adjust that accidentally. This solves that problem. My only issue is the controls are WAY too small for an iPhone 6s screen and because of that the faders are hard to control as you can't see them with your finger covering them up. I would much rather see bigger faders with less per page so they are easier to adjust as well as some sort of graphic control for each bus.
