The Identifier listens to a song and says which partner dances suit it. You can search it without an account: type a song's name and it shows the dances dancers have said fit the song, each with how sure the community is. Search is all the app does for somebody who is not signed in.
Signed in, you can hold your phone up while a song plays and the app identifies it live, then ranks the dances the same way. Your phone does no listening of its own. The sound goes to www.stage.africa, which asks the recognition service, ACRCloud, and keeps nothing of what it heard. Live identification draws on one monthly budget that Stage Africa pays for, with a ceiling of 20 songs a day for each account. When the month's budget is spent, identification pauses until the first of the next month, the app tells you when it is back, and search goes on working.
You sign in with your Stage Africa account, the same one the website and the forum use. The app opens the sign-in page in your browser. Type your e-mail address and the site sends you a six-digit code to type in, with a link in the same mail for when you are reading it on another device. Or continue with Google, and Google hands the site the address it has verified. There is no password to remember. If you have no account yet, the site makes one once you have confirmed that you are 18 or older and accepted the terms, whichever way you came in. If you have set up two-factor sign-in on your account, the site asks for your password and your second factor instead. Accounts are made and closed on www.stage.africa, never in the app. A Google link is removed under Account on the website, and to close your account go to www.stage.africa/close-account.
Signed in, you can also vote. For a song and a dance you say how well it fits, Perfect, Can Do, In a Pinch or No, and you can add a dance the list is missing. A dance you add is held as provisional until a curator or a trusted tagger confirms it. Before your first vote the app asks you to accept the contributor terms, once, because your votes go into a shared record that other people's answers are worked out from. You can also paste or share a playlist's link to have every track in it read for dance fit, and rate a track for social dancing, performance and practice.
Your standing as a tagger comes from agreeing with the record, first with tracks whose dances we already know and then with the weighted consensus, never from what you say about yourself. A tagger whose votes agree well and often earns a badge, which shows on their profile and their directory entry once they have said yes to showing it. No computer votes in the record.
The app plays music through YouTube's and Spotify's own players, or gives you a plain link, and no streaming service's data enters the record. It is for adults, carries no advertising, no analytics and no crash reporting, and asks for no location. The same app runs as a page on www.stage.africa, on the same account. Features may change, and this page is updated when they do.
