I’m building a child-parent safety application that must run on both iOS and Android and deliver three things flawlessly: real-time location sharing, geofence-based notifications, and a one-tap panic button that instantly sends the child’s coordinates to the parent’s phone. Beyond those essentials, I also need an activity log that keeps a searchable timeline of movements and alerts, a simple screen for storing multiple emergency contacts per child, and a smart battery-life alert so I know when the tracked device is about to run out of power. You are free to work in Swift/Kotlin, Flutter, React Native, or another stack you trust—as long as the UI is responsive and the location updates remain fast and battery-efficient. A lightweight backend (Firebase, AWS Amplify, Supabase, etc.) for authentication, data sync, and push notifications is fine; use what will get us to a reliable MVP quickly. Deliverables • Compiled iOS and Android apps ready for App Store and Play Store submission • Full source code with clear, modular structure and comments • Simple backend configuration files and deployment guide • Brief hand-off document covering build steps, environment variables, and how to add future features Acceptance criteria • Real-time position refresh no slower than 10 seconds in normal conditions • Geofence alerts fire within 5 seconds of boundary crossing in a live test • Panic button sends a push notification with accurate latitude/longitude 100 % of the time in QA testing • Battery alert triggers when remaining power drops below the threshold set in settings If this sounds like the kind of project you can deliver with security and reliability top of mind, let’s get started.
