This app is mostly functional, but could do with some improvements. 1) You can create “scenes” consisting of multiple lights, where, with the touch of a button, several lights all change to different preset colors. However, you can only do this with a literal picture. As in, you import a photograph, and then find hues in the photograph that you want to use. I would rather use the more intuitive basic interface to do this. (I worked around this somewhat by taking a screenshot of the color wheel in the app itself, and then importing it back into the app in the “scenes” function of the app. It doesn’t work quite as well as the real thing.)2) You can save five preset colors, but then you can’t access them from programs, scenes, or other areas of the app except for the basic function. Essentially, the basic part of the app works great, but then none of the other features use or communicate with the basic part of the app that actually works well.
