Fair playing time. Every match.

FairSub calculates substitutions in real time, so every player on your team gets fair time on the pitch.

You know the moment. Halftime is in two minutes, you've got 14 kids who all want to play, and somewhere behind you there's a parent wondering why theirs is on the bench. Tracking it in your head breaks down fast. FairSub does the math quietly, in your pocket, so you can stay on the sideline and focus on the game and the kids.

HOW IT WORKS

1. Add your team and pick the squad for the match.
2. Set the formation, match length, periods and rotation style.
3. Plan your lineup for each period. A color signal shows whether every player gets fair time.
4. FairSub builds the substitution plan: who comes on, who comes off, and when.
5. During the match, follow the countdown and tap to execute. Player injured? Skipped a sub? Made a manual swap? The plan recalculates in real time. Every player still gets their fair share.
6. After the final whistle, review who played when and track fairness across the season.

DESIGNED FOR THE SIDELINE

The best place for your eyes during a match is on the pitch, not on your phone.

• Keep the phone in your pocket and your eyes on the game. Sounds, haptics, and a lock-screen notification tell you when it's time to sub.
• An uncluttered, at-a-glance interface with only the info you need during the match.
• Dark mode and light mode for bright pitches and evening matches.
• Supports TalkBack, large text and reduced motion.
