FairSub makes fair playing time simple and joyful. Add your squad, start the match — every child gets their time on the pitch.
There's a better way. And it starts with a simple plan. ✌️
Enter your players once. They're saved for the season — just tap to select who's available for today's match.
Choose your formation, match length, and number of periods. Drag players into position. FairSub does the math.
A real-time countdown tells you when to sub — and who. Execute with one tap. Every child gets equal time on the pitch.
Everything you need. Nothing you don't.
FairSub figures out equal time — not just a timer, but a plan that adapts as the match unfolds.
Substitution cards show exactly which players to swap, with a countdown to each change.
Drag players between field and bench. Set lineups per period. Works for any formation from 3-a-side to 11-a-side.
See how much every player has played — per match and across the season. No spreadsheet needed.
Most apps give you a stopwatch and let you figure out the rest. FairSub gives you a plan.
The app simulates the entire match forward — period by period — and calculates the optimal substitution moments so every player ends up with as close to equal time as mathematically possible.
When something changes mid-match — an injury, a goalkeeper switch, a sub you missed — FairSub recalculates in real time and adjusts the plan. No manual recalculating. No spreadsheets. Just tap and go.
The free version is a real app — not a demo.
