Mobile App:
Although you need absolutely nothing to use the LUXA2 GroovyR with your Android or Apple device, there are mobile apps available for each. In this section we will take a look at the Android app, as installed on an Android 4.2.2 phone.
The first screen capture shows the main page of the app, where each of the four larger circles is a button for the features provided. There is an equalizer, a music player, Bluetooth controls, and an Internet radio.
The equalizer is pretty cool, since it gives you a variety of presets, as well as the ability to use sliders to set your own levels for the various bands. Unfortunately, this works only with the analog output of the 1/8" stereo jack, and not with Bluetooth.
The image below shows the built in music player, which will let you play your local digital music files. Most devices have a player already, which may be more feature packed, so this isn't really necessary.
The next image shows the main page of the Internet radio portion of the app, which is something like Shoutcast as it has links to tons of stations in a variety of genres.
The below left screen shows the first sub-menu for finding an Internet radio station. You have a variety of genres in the "Radio List", and I am only slightly twisted up by the mix of upper and lower case entries (ha). If you select "music" in the below left image, you will get the screen shown in the below right image. And from here, you can select any of these types of music and find a station ready to suit your tastes.
The Internet radio is by far the coolest part of the app, but overall the app is not necessary. Most devices have similar apps installed that may do a better job at the same task, but for me I am mostly just streaming from Pandora or my Qloud server and don't need anything else installed to enjoy the GroovyR!
