Retro Pod alternatives

This is the first light syncing app for phillips hue that I've seen that is completely free. Like I said in pros, the setup was easy. The Spotify integration was quick and painless, and although it didn't find my lights immediately, I was able to connect with the ip address of my lights, which wasn't too hard. The only issue was that for some songs it would seem weirdly synced, and I couldn't figure out what part of the music it was trying to flash with. There is a color wheel to select colors from, but mine ignored that and flashed through all the colors of the rainbow -- I don't know if I selected it wrong, or what. Either way, I plan to keep using it! I feel like it would be good for syncing lights to music for a party, but not exactly something I would use in my every day yet.
