Structural fact — engine capacity
When the client shares live tournament data — active organizers, completed events — we'll swap these figures for real platform metrics.
The Context
One platform that runs the tournament and officiates it.
Cataleague handles event creation, player registration, brackets and live scoring for any sport, traditional game or esport — with a Virtual Referee that settles calls digitally, multiple admins able to work the same event at once, and social sharing that keeps players and fans engaged between matches.
On top of the operational side, the client wanted players and fans to stay engaged between matches — sharing scores and leaderboards socially, and browsing bite-sized reads about the games and sports on the platform.
The Challenge
Tournament management lived in spreadsheets and group chats.
Organizers ran events through spreadsheets, WhatsApp groups, and paper brackets — a setup that fell apart the moment a tournament grew past a handful of players. Registrations got missed, score updates lagged, referee calls turned into disputes, and nobody had a clear view of how an event was actually progressing.
The brief called for one platform that worked across sports, traditional games, and esports alike: fast event creation, registration for up to 32 players and 75 matches, multiple admins working the same event without stepping on each other, and a way to officiate matches digitally instead of arguing about them after the fact.
Our Approach
Speed and fairness, built in from day one.
We mapped the organizer's workflow end to end — event creation, registration, live play, and post-match sharing — then built each piece to hold up under a real tournament, not just a demo.
One Flutter app, every sport.
A single cross-platform app for iOS and Android that treats esports, traditional sports, and games as the same underlying event model.
A web dashboard for organizers.
Angular-powered event management tools for building brackets, assigning admins, and monitoring a tournament as it runs.
Officiating built into the app.
The Virtual Referee feature lets admins call matches from their phone, with scores publishing live the moment a game ends.
Engagement as a feature, not an afterthought.
Social score-sharing, live leaderboards, and a dynamic mini-reads section keep players and fans coming back between matches.
Weekly demos tracked the platform from empty event shell to a fully officiated, shareable tournament experience.
The Impact
What this means in practice.
01
Organizers can spin up a full 32-player tournament in minutes instead of days.
02
The Virtual Referee feature moved officiating into the app, cutting on-field disputes dramatically.
03
Live leaderboards and score-sharing turn events into shareable moments across social platforms.
04
Multi-admin roles let one event scale across a full organizing team without conflicting updates.
05
Mini-reads and gamification keep players and fans engaged between matches, not just during them.
06
One Flutter codebase means every new feature ships to iOS and Android at the same time.
