Live Line App

Building a Cricket Live Score App from Scratch

Live Line is a real-time cricket live score app we built for a Faridabad-based client. The app covers international cricket — IPL, World Cup, T20I series, ODIs, and Test matches. Fans get ball-by-ball live scores, live match predictions, scorecards, match schedules, and push notifications — all synced in real time from a control panel the client's team operates.

We built it as a cross-platform React Native app connected to a Firebase-powered backend, so scores update instantly across all devices the moment an operator enters them in the dashboard.

What the Client Needed

The client wanted to build a cricket live score app that covers major international tournaments — IPL, ICC World Cup, Asia Cup, T20 leagues, and bilateral series. The app needed to deliver real-time scores, match schedules, player stats, and completed match results in a clean, fast interface.

It also needed to handle traffic spikes — especially during IPL season when thousands of fans are checking scores simultaneously. The system had to stay fast and reliable even at 5,000+ concurrent users.

How We Built It

• Real-Time Score Updates: The app shows ball-by-ball updates, live scorecards, run rates, and match statistics. Firebase Realtime Database handles the sync — when an operator updates a score in the admin panel, it reflects in the app within milliseconds.
• Tournament Scheduling: Users can browse upcoming matches, tournament brackets, and fixture schedules. Everything is organized by tournament so fans can follow their local leagues easily.
• Push Notifications: We integrated push notifications for match starts, key moments (wickets, milestones), and results. This keeps users coming back even when they're not actively watching.
• Live Match Predictions: The app includes live predictions that update as the match progresses — win probability, projected scores, and session forecasts. This adds an extra layer of engagement for fans who want more than just raw scores.
• Seamless Dashboard Integration: The app pulls all its data from the Live Line Dashboard — the companion web admin panel we built alongside the app. Operators enter scores there, and the app displays them in real time. Both products were designed and delivered as a single package.

Tech Stack

We used React Native for cross-platform development — one codebase for both iOS and Android. Firebase handles real-time data sync and authentication. Node.js powers the API layer that connects the app to the admin dashboard. This stack keeps things fast, reliable, and cost-effective since we didn't need to build separate native apps — and Firebase scales automatically during IPL traffic spikes.

Results

The app handled 5,000+ concurrent users during peak IPL and World Cup seasons without performance issues. Fans could follow multiple matches simultaneously, and the client had a fast, reliable product that cricket fans actually wanted to use for live match tracking.

Conclusion

Live Line shows what you can build when you pair React Native with Firebase for real-time use cases. It's a cricket live score app built for serious cricket fans who want IPL, World Cup, and international match updates — fast and reliably.
