EOA is a utility app designed for iPhone users to streamline office management tasks. It allows users to view and manage their incomplete tasks effortlessly, ensuring that all office affairs are organized. The app features a scheduling function that enables users to book meeting rooms, shared workspaces, and negotiation rooms while inviting other employees to join meetings. During meetings, participants can check in by scanning a QR code and gain access to various room facilities such as control screens and lighting systems. After meetings, users receive minutes and assigned tasks for follow-up.

In addition to internal management, EOA facilitates visitor management by allowing users to send invitations to external guests. Visitors can complete their information before arriving at the designated meeting room at the scheduled time. The app also automatically generates attendance records based on user access logs, eliminating the need for manual check-ins. Overall, EOA enhances productivity and organization within the office environment.
