Availability & current status

The app is currently available in a limited internal/beta setup and requires a personal Spotify Premium account to function. Due to Spotify's current rules around API quotas, it has not yet been released as a public Google Play listing, but is used in smaller training groups and as a reference project in my consulting work.
