Cross-Platform GPS Tracking App

I need a straightforward GPS-tracking application built for both iOS and Android. The primary goal is reliable, continuous location capture and display, wrapped in a clean, intuitive interface that feels native on each platform.

You are free to choose the most appropriate toolkit—whether that’s Swift and Kotlin natively, Flutter, React Native, or another proven cross-platform framework—as long as performance and battery efficiency remain solid. I will supply the branding assets; you will handle architecture, coding, simple cloud or on-device storage of location data, basic privacy safeguards, and submission-ready builds for both App Store and Google Play.

Deliverables
• Full, well-commented source code
• Test builds for iOS & Android
• Brief deployment guide and store-submission assistance
