This app is incredibly glitchy and frustrating to use. I can only make one lighting adjustment to one bulb before the app freezes. I then have to choose it and open it again to adjust the light settings further, or to adjust another bulb. After reducing the brightness of a bulb it will still display that it's at 100% intensity on the home screen despite showing a different percentage in the bulb settings that reflect the actual brightness of the bulb. Not a good app.
