About

CDRoster

Read full description

CDRoster brings your ecclesia's duty roster to your iPhone and iPad. See your upcoming duties at a glance, request a swap when you can't serve, or volunteer to fill an open role. Browse the full schedule in a month calendar, look up members in the directory, and keep up with ecclesial news, announcements and surveys. Add a home-screen widget for your next duty, or subscribe to your duties from your own calendar app. FOR EVERY MEMBER • Your upcoming duties, with swap requests and open roles you can volunteer for • A colour-coded month calendar of meetings, marked on the days you're rostered • Announcements with photos, attachments and in-app surveys • The ecclesia directory and shared documents • Your profile: availability, role preferences, household, qualifications, Sunday School classes and notification settings FOR COORDINATORS AND ADMINISTRATORS • Run and publish rosters, assign or reassign duties, and open slots to volunteers • Compose announcements with photos, attachments and member surveys • Sunday School years, classes, teachers, enrolments and attendance • Congregational attendance and child-safety (WWCC) credentials • Member administration, ecclesia settings and spreadsheet exports These tools appear only for members who hold the role — a member sees none of them. DESIGNED FOR IPAD On iPad, Calendar, Members and Manage use a two-column layout, so the list and the detail sit side by side. Home becomes a dashboard, forms and articles keep a comfortable reading width, and an extra-large home-screen widget shows your next duty plus what's coming up. Hardware keyboard shortcuts, all four orientations, Split View and Slide Over are supported. CDRoster works with your ecclesia's existing CDRoster account — you'll need an invitation or login from your ecclesia to sign in. There is no public sign-up and nothing to buy in the app.
