OR DOING THEM ON-THE-FLY IN YOUR HEAD
Stop planning substitutions
by hand.
Fair. Position-aware. Done in seconds.
When the game changes, Sub Boss adapts — and keeps every player's minutes fair.
Coaches lose track. Kids miss out.
It shouldn't be that hard.
The app
Everything on one screen.
Sub Boss plans your rotations, manages substitutions, and tracks every player's minutes — so game day stays organised from tip-off to the final buzzer.
It doesn't replace your judgement. It backs it up — with a clear plan before the game, live information during it, and instant recalculation when things go sideways.
And unlike the cluttered dashboards and confusing interfaces of other substitution tools, Sub Boss is designed to be read at a glance. Clean visuals, intuitive layout — built for the sideline, not a spreadsheet.
That same clarity carries into your post-game reports — store and review every player's minutes across every game.

Why Sub Boss
Built for basketball.
Every feature — positions, rotations, court view — designed specifically for basketball. Not a generic sports app with a basketball skin.
Balanced playing-time plans built around your roster, game length, positions, and individual minute targets.
Made an unexpected sub? Sub Boss recalculates the remaining plan around your original minute targets and settings — or snaps back to the planned rotation.
No internet connection needed. Sub Boss works fully offline during games.
Always know who's on court, who's due off, and how many minutes each player has logged — this stint, the whole game, or on the bench.
Team and player data stays on your device. No ads. No data selling. Ever.
