For every wave, there is a path
and for every Bahaar there is a companion

Marine mobile applications have become an essential tool for modern fishermen, offering navigation, weather, and marketplace features. However, existing solutions fail to adequately serve the Bahraini fishing community due to limited localization for Bahraini users, interfaces primarily designed for Western markets, and the fragmentation of critical tools across multiple paid applications.

Bahaar is a bilingual mobile application developed to address the unmet navigation, safety, and fishing support needs of both professional and recreational Bahraini fishermen. The application consolidates marine navigation, real-time weather and tide data, AI-based fish species identification, fishing trip logging, and a peer-to-peer fish marketplace into a single, intuitive platform designed for users of all technical backgrounds.

The application was built using Flutter and Firebase, enabling cross-platform deployment on both Android and iOS. An EfficientNetB0 model running on device classifies five commercially significant fish species with a confidence threshold of 70%. Additionally, a celestial navigation module provides GPS-independent positioning as a safety fallback, ensuring continued usability in areas with limited connectivity.

All six feature modules passed unit, widget, integration, and performance testing, confirming the system is functionally complete and ready for user-facing evaluation. The project demonstrates that a locally tailored, unified marine application can meaningfully improve the safety and productivity of Bahraini fishermen.
