Fair playing time.
Every match.
FairSub calculates substitutions in real time. Every player gets fair time on the pitch.
Countdown to every sub.
FairSub is built for the coach with a full bench, a ticking clock, and no time to do mental math.
Take a closer look.
Real-time substitutions
What happens on the pitch is reflected in the app, as it happens. Skip a sub, swap a player, manage an injury: the plan recalculates so every player still gets their fair share of playing time. No fixed timers, no preset rotations.
Designed for the sideline
The best place for your eyes during a match is on the pitch, not on your phone. Sounds, haptics and a lock-screen notification tell you when it's time to sub. Keep the phone in your pocket and your eyes on the game.
Set your gameplan.
Choose your formation, match length, periods and rotation style. FairSub does the math before kick-off so you can guarantee every player their share of minutes.
Set the team. Period by period.
Pick from over 40 formations, from 3v3 to 11v11. Plan a starting lineup for every period, so every player gets a fair chance to start. Arrive at kick-off with the team set.
Position-aware substitutions
A defender replaces a defender. Fair playing time always comes first, but the engine prefers like-for-like swaps. Your tactics hold through every change, from kick-off to final whistle.
Statistics that show the complete picture.
Before kick-off, a gentle nudge shows who's been playing and who's been sitting out. After the final whistle, match summaries reveal who played when and how fairly. Across the season, every player's matches, starts and minutes add up to the full picture.
Monthly Report.
Every player's time on the pitch and match rate, for every match of the month. One secure link to share with club and parents.
Plans change.
FairSub adapts.
Eyes on the pitch.
Not on your phone.
A glance is all it takes.
Free to start. Fair to pay.

Questions.
Who is FairSub for?
Volunteer and grassroots coaches of youth soccer teams, ages 5 to 12. Any format from 3-a-side to 11-a-side, any squad size, any number of periods. The coach who wants every player to get fair time on the pitch, without mental math on the sideline.
How does FairSub calculate substitutions?
FairSub simulates the match forward and calculates every substitution needed for fair time. What happens on the pitch is reflected in the app, as it happens. If you miss a sub or a player gets injured, the plan recalculates automatically. Why timers fail
Why does equal playing time matter?
Every kid who steps onto the pitch gets a chance to touch the ball, make decisions and feel part of the team. That's where confidence grows. That's where the love for the game is born. Why equal playtime matters
Why doesn't FairSub track goals?
FairSub counts minutes, not goals. At ages 5–12, development happens through playing time. Every touch, every decision, every moment on the pitch.
What is the Monthly Report?
A shareable monthly summary of your team's matches. Every player's time on the pitch and how often they were selected. Generate it in the app, share a link with club and parents. Protected by a team-name login so children's data stays private. Requires the Coach upgrade. How coaches use it
Is FairSub really free?
Yes. The full substitution engine, lineup builder and match history are free. No trial, no limits. The optional Coach upgrade (USD 14.99 per year) adds position-aware substitutions, Live Activity, flexible rotation styles and the Monthly Report. The free version is not a demo.
Do I need an account?
No. FairSub works without an account. Your data stays on your device. No servers, no sign-up, no password.
What about my players' privacy?
FairSub stores match and gameplay data, not child data. Only first names and a team name. Everything stays on your device. Reports are protected by a team-name login. We do not collect data we do not need, and we treat anything about children with extra care. GDPR and national laws set a high bar around minors' data, for good reason. A focused coaching app does not need photos, parent contacts or free-text family notes to do its job. Our privacy stance
Does the app work offline?
Yes. Everything is stored on your device. No internet connection needed, including during live matches.
