Fandaharam-potoana is an offline worship management system designed for churches, enabling the projection of hymns, Bible verses, and service schedules without relying on internet connectivity. The application eliminates the need for manual PowerPoint preparation by providing a structured and reusable service flow.

The system combines a desktop projection app and a mobile companion app. Congregation members simply scan a QR code to receive the service program directly on their phones, allowing them to follow along seamlessly during worship — entirely offline.

Additionally, programs can be imported and exported as JSON for easy backup and quick transfer between devices.
