Like other reviewers, Ive tried pretty much every hue related app out there, and this one is by far the best app for creating and editing your own color themes. From the variety of looping effects to the way you can create your own color palettes and sync them to your own music is fantastic. Best of all, no in app purchases! The developer isnt greedy....Buy it once and you can create any variety of looping colors that you want. I love that I can assign a group of bulbs together and have them all synced to the same colors. Its the only app you really need!
