Doer is the calm, simple way to run your day. TODAY, AT A GLANCE Your day as one clear timeline. Meetings show their Teams, Zoom or Google Meet logo, and a meeting with a link gets a Join button when it's time. Tasks sit beside them with their start and end, and Doer shows the free time in between. JUST SAY IT Press the Action button (set Doer Voice in Settings › Action Button › Controls) or tap Doer Voice in Control Center, and talk. Doer listens in the Dynamic Island, writes what you say as you say it, and understands it on your iPhone, with Apple Intelligence where available: "tomorrow, dentist from 2 to 3", "call with Sara Friday at 10 for half an hour on Zoom". Check the day, time and length, then tap Add. Speech is recognised on your iPhone, in English. A MEETING IN ONE TAP Type a meeting in + and Doer suggests online or in person and the app — Teams, Zoom, Google Meet or FaceTime. One tap to accept, one more to change. THE WHOLE WEEK Summary shows the whole week, day by day — your tasks and meetings in order, with their times. Tap a day to jump to it. PROJECTS AND NOTES Keep projects and notes together, newest first. Filter to just projects or just notes in one tap. Projects show their next task and progress. A LITTLE HELP, WHEN YOU WANT IT • Plan my day fits your loose tasks into today's free time. • Break it down turns a big task into a few clear steps, with Apple Intelligence (on iPhones that support it). WIDGETS Six widgets for your day and your week — Today, Up next, Progress, This week, Coming days and Week load — on the Home Screen, the Lock Screen and in StandBy. BUILT FOR iPHONE AND iPHONE DUO Black and white design with Liquid Glass, smooth animations and gentle haptics. Light and dark mode, Dynamic Type and VoiceOver. On iPhone Duo, the tabs sit in the side bar of the outer screen, and when you open it your day, week, projects and settings spread across the larger screen. PRIVATE BY DEFAULT No account. Your tasks stay on your iPhone, in your own iCloud and, if you allow it, in your own calendar. Voice and Apple Intelligence run on the device.

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.
