Concertmaster is a classical music front-end for Spotify.
It's splitted in several projects. This one provides only the iOS app. (There's a web player as well!) All data comes from an API which, in its turn, uses the Spotify API. Spotify doesn't allow multiple apps using the same API key, so you can't fork only the app and use the Concertmaster API - you have to fork both.
It's an iOS app. You can get it directly on the App Store.
The player itself is full of features, so there is a wiki explaining them all.
Concertmaster uses SwiftUI, so you'll need MacOS Catalina and XCode 11 to build it (and iOS 13 to test it on a device).
Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
Concertmaster composers and works information come from Open Opus, a free, wiki-style, open source database of classical music metadata. You can review existing info or add new entries to the database - any help will be appreciated!
Concertmaster is free to use but it runs on web servers that cost us money. You can help us by supporting us on Patreon - any amount is more than welcome!
