I downloaded this app in order to play music on my new Oregon Scientific Clock Radio (CIR-100), and I love it! It works great! For the best sound quality, it's best to play your music using your wifi network, instead of Bluetooth) if possible). Note: you do need a second app to pair the clock with your phone/device. The radio app lets me choose between music already on my iPhone (iTunes), as well as iHeart Radio and Spotify. Because my friend has the same clock, we discovered that we could use them as wireless speakers to play music from both our phones in multiple rooms, and we can even use it for conference calls!
