FairSub

Fair playing time. Every match.

FairSub helps youth soccer coaches plan substitutions in real time, so every player gets fair playing time on the field.

You know the moment. Halftime is two minutes away, you have 12 kids who all want to play, and a parent behind you is wondering why their kid is still on the bench. Tracking it all 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 choose the players for the match.
2. Set the formation, match length, periods, and rotation style.
3. Plan your lineup for each period. Color signals show whether every player gets fair playing 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 make each sub. Injury? Skipped sub? Manual swap? The plan recalculates in real time, so 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 soccer match is on the field, not on your phone.

• Keep your phone in your pocket and your eyes on the game. Sounds, haptics, and Lock Screen notifications tell you when it is time to sub.
• An uncluttered, at-a-glance interface with only the information you need during the match.
• Dark mode and light mode for bright fields and evening games.
• Supports VoiceOver, Dynamic Type, and Reduce Motion.
