Charts, keys and slides from one plan.

Build the order of service once. The band gets each song in the singer’s key, the volunteers get their reminders and the slides are ready in cOS Presenter.

Churches start on December 1, 2026, free during the beta.

Plan the service once.

Songs, keys and who leads each part sit in one order of service. Send it, and the band, the volunteers and cOS Presenter all have it.

Sunday in Covenant OS
The order of service for Sunday, October 25 in cOS, with each song’s key and leader, and buttons to open it in Presenter and send it to the team
The order of service for October 25 on a phone, with each song’s key and leader

Each song in each singer’s key.

Move a chart to any key, and the chords follow. The band reads it full screen on a tablet, with the current line lit.

Fill every spot on the team.

Volunteers answer from their phones, and a volunteer who can’t serve asks a free teammate.

Who is serving for four Sundays by team in cOS, with who said yes, two open spots and a lapsed safety training flagged
