Remember each person and plan the next act of care. CELLOG helps pastors, administrators, and cell-group leaders at Sejong All Nations Church organize member lists, pastoral visits, and follow-up notes. The app interface is currently in Korean. • Record care: Keep notes about meetings, calls, visits, prayer, and other activities. • Organize members: Ministers and leaders can view assigned members, birthdays, and recent care records. • Track report reading: Administrators and ministers can privately distinguish their own read and unread reports. • Plan follow-up: Record who needs another call or visit and when to reconnect. • Use the calendar: Browse records and birthdays by date and add new entries. • Find and export: Search or filter records and share a CSV file. • Manage groups: Create a group or join with an invitation code, then manage member roles and departments. Members have administrator, minister, or leader roles and belong to Adult, Young Adult, Youth, or Sunday School departments. Authors can view their own reports; within a shared department, ministers can read leaders’ reports and administrators can read ministers’ and leaders’ reports. Administration alone does not grant report access, and readers cannot edit or delete other authors’ reports. Share invitations and CSV exports through the iOS share sheet. An email account and an internet connection are required. The app is free, with no advertising, subscriptions, or in-app purchases. Privacy information and support are available through links in the app and on the support website.
