The Android app is solid. I don't remember running into any bugs recently, and (1) the app supports Android tablets well (2) the app for classical music "Classical" works is also top-tier. I switch between the iPhone app and Android app frequently, and I really can't tell any difference between the two versions. The Android one supports Chromecast, although I have had some trouble with it in the past.

The Windows app is ok, but I haven't used it as much, so I can't provide much feedback.
