B-Ball Subs

Fair substitutions made simple. Generate balanced rotation schedules for your basketball team so every player gets equal court time. Perfect for youth and junior coaches.

B-Ball Subs takes the stress out of managing substitutions during basketball games. Instead of scrambling to track who's been on and off the court, generate a complete rotation plan before the game starts. Every player gets their fair share of court time — calculated automatically so you can focus on coaching, not maths.

Manage multiple teams, track game progress in real time, and handle unplanned injuries or swaps mid-game without losing track of who's played how long.
