Guide

Building sports apps: clubs, athletes and communities

01

Three kinds of sports app

Sports apps usually solve one of three tasks. Organisation: teams, dates, fees, communication. Performance: training data, video analysis, statistics. Matching: bringing together athletes, coaches, clubs and scouts.

The technology behind them differs widely. Organisation needs reliable notifications and roles, performance needs data models and analysis, matching needs search, profiles and trust.

02

Matching and profiles

For SportsForce we built a recruiting app for US college sport: athletes and coaches find each other through a swipe mechanic, matching runs at university level, and candidates can be ranked. The app is based on FlutterFlow with a Supabase backend and custom code for the special parts.

03

Minors and data

In youth sport many users are minors. That affects parental consent, the visibility of profiles and contact between adults and young people. We plan these rules as part of the product — they are hard to add afterwards. For training features see the fitness app page.
