Limited functionality and not user friendly at all. It takes around 5sec to open the app on my xs max. That’s not a huge deal, but generally remotes are about accomplishing an adjustment quickly and effectively. This app completely fails at providing convenience. For instance, If you need to change the volume after waiting for the app to open you have to select the projector from a network list (as far as I can see there is no way to set a default) once you connect you are either kicked to the “contents” screen which doesn’t offer any adjustments or you are left at the connection screen which will send you to the “contents” screen if you try to select any option. From the contents screen you can get to the menu and select target device and finally the control tab, but when you finally get there you’re greeted with a clunky slider bar for volume control and an input selection. Absolutely no way to access the menu to adjust picture setting, brightness, orientation etc. Moreover even if you don’t close the app you are disconnected as soon as you switch to another app. I appreciate the free app, but it really feels like minimal effort has gone into it.
