App Overview
Lighter attendance work, clearer operational screens
Checkin is an attendance management app designed so organizers can process attendance quickly while participants check in without friction. From group creation and invitations to attendance records, member management, and announcements — every workflow lives in one place.
Key Features
Choose the check-in method that fits the situation
You're not locked into one method — pick the easiest check-in flow for the way your group runs.
Check-in
Verification Code
Members enter a 4-digit verification code for fast check-in — perfect for remote meetings or simple attendance confirmation.
Check-in
GPS-based Check-in
Verifies both the configured location radius and time window so members can check in with one tap.
Operations
Member Management
Manage not only members who joined via invite link, but also members who don't use the app — Hosts can add them directly.
Reports
Today, Calendar, and Stats
See today's attendance status at a glance and review cumulative trends through the calendar and period-based statistics.
Communication
Announcements and Notifications
Hosts send announcements and Members never miss important notices — through both the in-app inbox and push notifications.
How It Works
An intuitive flow for both Hosts and Members
Even though both roles use the same app, the features each one needs are naturally separated.
