Works Fine

Does it's job, glad it exists. Very helpful on set to stand back and dial in settings. Haven't tried on an iPad but have a smooth experience on my iPhone 13. Sometimes takes a minute for the device and app to link.

Terrible app

Honestly, this app would be better if it didn’t exist. You waste a ton of time trying to get it to work and it’s a train wreck.

Spend your time learning how to use the lights or better yet, selling these lights to somebody else.

Crush

It crushes immediately by touching slider. Every time. No matter how many times reinstalled.

App worked at one point - crashes constantly

The App worked at launch but now constantly crashes even after uninstalling it and re-installing it. If you go into a fixture and use the sliders it immediately crashes the whole app.
