Child Tracker App Development

I’m building a mobile application that will run on both iOS and Android and link directly to my own hardware device. Once the phone pairs with the device, the app must show a live map, let parents create and manage multiple child profiles, and reflect each child’s real-time location on that map. Smooth pairing, rock-solid connectivity, and low battery impact are priorities. the app should also be able to track when the device has detected a fall\crash and send an alert with high urgency Deliverables I’m expecting • Full source code for iOS and Android, neatly organised and documented • A working pairing flow integrated with the device SDK or protocol I provide • Live map screen with location updates and the ability to switch between child profiles • Basic UI that I can skin later, plus clear hand-off instructions for publishing to both stores • Short video demo and test builds for user acceptance To help me choose quickly, please attach examples of past mobile projects that show your ability to handle hardware integration, maps, or multi-profile user flows. A concise outline of your approach and timeline is welcome, but past work is what will speak the loudest.
