Indeed, Loopy is developed for iOS devices only and at some time someone suggested a build for Android phones but due to the fact that every Android device is different in the terms of hardware, libraries, drivers, the process of developing the application for this operating system is somewhat hard to accomplish.
But beside all this there is an application called PocketBand Lite which promises to fulfill what you actually need. Give it a try from the Play Store and see if it's good enough for your purpose.
