Stumbled upon this app because it appears to be virtually the only app that supports Hue and LIFX together. Imagine my surprise that the only option is so incredible, and better than about anything Ive used that controls Hue alone. One great thing about the app that Ive realized since getting some LIFX bulbs in the mix is how well everything works together—and how well the UI handles both platforms. Whats really incredible is the ability to have animations that you can control with very fine precision. In fact, precision is painted all over this app. This has the result of being a little daunting, but there are lots of available inbuilt presets of you dont want to do any tinkering. But that brings me to the "Featured" in-app purchases... These purchases are preset packs. They dont really add any features to the app, just scenes that you could make on your own for free, in theory. I am completely okay with this—what you are paying for is the convenience of not having to set up these incredibly specific presets/animations yourself. If the dev keeps supporting the app, I know Ill be happy to buy the Christmas or Halloween packs when those holidays roll around. But if you dont want to do that, you arent restricted in any way whatsoever by not buying the packs. If I have a couple of criticisms, they arent deal breakers at all. First (a small gripe), the notification center widget uses space a little liberally; Id prefer it if the straight list at least was presented in 2 columns, so as to not use so much space. And now having used it for a bit, the biggest problem I have is that the notification center widget has been very unstable after adding some LIFX bulbs. The app is fine, but the widget crashes, and is otherwise unreliable (LIFX bulbs arent always responsive with the widget when they work fine with anything else). Ive deleted and re-added scenes triggered by the widget, but it has still been shaky. But overall, this app is worth the money. If you want to setup scenes yourself, itll take some effort, but your end result will be exactly what you want. And once you get over the learning curve, its probably quicker to build a scene in this app than most.
