Rune, a coach's toolkit for matches and practice

Rune, from S3i, is a mobile and web app for sports coaches to manage and monitor their players in matches and practices.

Under the hood

Design decisions

Tactics that move

A coach draws a play on the tactics board frame by frame, with passes and runs, then plays it back as an animated scenario for the team.

AI on the match footage

Rune detects the players in match video and turns the footage and athlete data into tactical insights for the coach.

Practice and matches in one place

Training drills, match plans and each player's development sit in the same app, so a coach follows a player from practice to match day.

Built on Unity

Built on Unity, so the same tools run as a mobile app at the pitch and in a browser.
