T-Navi

T-Navi is an Android application designed for vehicles like buses and trains to keep passengers informed about their current journey. It uses GPS to track the vehicle's position in real time, automatically announces upcoming stops, and displays the full route on an onboard information board.

Key features:

• Real-time GPS-based position tracking
• Automated stop announcements
• Route visualization on an information board
• Multi-language support (Bulgarian, English, Dutch, German, Polish, Czech)
• Built natively in Kotlin for Android 8+

Distributed exclusively through Google Play, with a privacy-first approach — location data stays on-device during active routes, and analytics are anonymized in line with GDPR.
