I’m creating a mobile app that lets casual players form private or public groups, track live horse-racing and football stats supplied by the app itself, and compete for the top spot on a shared leaderboard. The core experience is a friendly, low-pressure competition environment rather than a professional training tool, so the interface should feel welcoming and social. The build needs to run smoothly on both iOS and Android from a single code-base if possible. I already have reliable data feeds lined up; your job is to pull that data into the app, structure it so groups can set up weekly or one-off challenges, and display rankings in real time. Standard account creation (email, Apple, Google), push notifications for challenge updates, and basic in-app chat will round out the first release. Deliverables: • Complete source code for iOS and Android builds • Clean, well-documented API calls to my data provider • Simple admin panel or config file where I can adjust scoring rules for each sport • A short deployment guide so I can reproduce the builds and push updates myself I’m happy to discuss preferred frameworks, but React Native or Flutter familiarity will be a plus. Let me know what similar projects you’ve shipped and how quickly you can move from wireframes to a testable build.
