If you want your Philips Hue lights to dance along to your music, then Ambify might be your cup of tea.
The app takes your local music library on your iPhone, analyzes it, and then lights up your living space and has your Hue lights dance to the music. You can even AirPlay the app's visualizer to your television through the Apple TV.
Something like this can be great for dance parties. Unfortunately, the iPhone app doesn't support Apple Music, but the Mac app does, which is nice if you want to play around with Ambify on your Mac.
The iPhone app is $3, while the Mac app costs $10.
