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. ### 1/5 — Terrible app *2023-09-21* 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. ### 1/5 — Crush *2023-04-16* It crushes immediately by touching slider. Every time. No matter how many times reinstalled. ### 2/5 — App worked at one point - crashes constantly *2023-04-01* 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. ## Frequently asked questions about starCTRL ### What lighting fixtures does starCTRL support? starCTRL supports Quasar Science Rainbow 2, Double Rainbow, and Astra IP fixtures.
