I have an existing Android and iOS application that needs a focused refresh. First, selected screens require a facelift so the tracking features feel clean and intuitive rather than bolted-on; think streamlined layouts, consistent colours and modern icons that match current platform guidelines. Alongside the visual work, I need solid location-tracking functionality implemented end-to-end. The app must request the right foreground and background permissions, capture accurate GPS data with minimal battery drain, and surface that information inside the updated screens—live map view, status indicators and a concise history log. All logic should be shared where possible (Kotlin Multiplatform or React Native welcome, but I am open to native Swift/Kotlin if you prefer) and thoroughly tested on recent iOS and Android versions. Deliverables • Redesigned tracking-related UI components packaged for both platforms • Integrated location-tracking module, running in background and foreground, with graceful degradation if permission is denied • Buildable source projects plus brief setup notes and a short demo video that proves the flow works on real devices I’ll be available for quick feedback rounds and can supply current source code as soon as we agree the milestones. If you have shipped apps with reliable GPS or logistics features before, I would love to see a sample.
