Download the host app, unzip it and double-click Install Ward Choir. It installs Python if the PC doesn't have it, opens the firewall so phones can connect, and puts Ward Choir on the Desktop and Start menu. The app serves the director's console on your PC and a page for singers on the same Wi-Fi. All songs, recordings, programs and bookmarks are stored on that PC — in folders you choose.
Nothing to install and no account. They open the address shown on the console (or scan its QR code), tap Singer / Accompanist, pick a part and put in an earbud. The director's Play starts every phone within a few milliseconds, and their part sounds above the others.
681 hymns and songs from the Church's library with separate voice parts, their printed sheet music with click-to-play, highlight and autoscroll — plus your own recordings, part by part, or the app writes the music for you from a MIDI file.
Only your email and whether your host subscription is current. Your choir, its songs and recordings never leave your computer, and rehearsals run with no internet at all.
An Android phone can, through Termux — see the Android notes under Download on the account page. iPhones cannot run the host, but any phone can be a singer or the director's remote console.
On the I'm the director page, with your account's email and password — or with the licence code from your account page, handy on a shared chapel PC. The PC remembers it; the only time it talks to this site is to renew.
$10 a year for the host account. Singers are always free. Cancel any time from the account page; hosting keeps working 30 days past the last check-in, so a chapel without internet is fine.
Restart Ward Choir — the PC has a new address, which the console and QR code then show. If Windows asks about the firewall, allow it (or run allow-firewall.bat once). On a hotspot, the phone providing it usually cannot join as a singer itself.
