Overview

Survivor Bracket turns watching Survivor into a competitive sport. Users join or create private leagues with friends, make weekly predictions before each episode — who gets voted out, who wins immunity, who plays an idol — and earn points based on accuracy. A live leaderboard keeps the competition fierce all season.

Features

Private league creation with shareable invite codes
Weekly prediction forms locked at episode air time
Automated scoring based on episode results
Season-long leaderboard with point breakdowns
Player profiles and season stat tracking
Push notifications for lock deadlines and results

Technical Details

The app uses Firebase Firestore for data persistence and Firebase Cloud Functions to automate the scoring pipeline — when an admin posts the episode results, scores update instantly for every user in every league. React Native handles the cross-platform mobile experience with a custom tribal-council-themed design system.

Engineering Challenge

The prediction lock system was critical to get right. Picks had to be immutably sealed at exactly the right moment without relying on client-side timing (which users could manipulate). Cloud Functions with server timestamps solved this cleanly.
