Jim Wanner: Early Music Companion was developed as therapy during the covid pandemic. I am now retired, I kept the composer database up to date and fixed any problems that I find or that were reported to me.

When I reached my 90th birthday, I decided I could no longer, in good conscience, continue to charge for the Early Music Companion mobile app. I have kept it up to date and available as long as I can, and I’m happy to have found a new home for it.
