Masook Instansi Simpatika is an online biometric attendance system that uses face detection and liveness detection for authentication. It is developed by Masook for Android devices and is available for free. The system is designed to support attendance processes even when there is no internet connection available.

The system consists of two parts, SIM (Sistem Informasi Manajemen) for management and a mobile app for attendance activities. The mobile app enables users to authenticate their attendance using facial recognition, identify and capture user's face, synchronize schedules, select organization or institution, attend using personal or institutional devices, mass attendance in various areas, and record offline and online attendance history. On the other hand, SIM allows setting up geo-location attendance areas, determining multi-location institutions, monitoring data and dashboard, managing users and organizations, scheduling and working hours, generating periodic attendance reports, recording user attendance history, and manual approval of attendance.

Overall, Masook Instansi Simpatika is a comprehensive and efficient attendance system for institutions and organizations. With its multiple features, it offers a complete solution for attendance management.
