Before the game
Set the squad, player availability, positions, match requirements and the rotation approach that best fits the team.
SMART SUB SAVER / EX PARVIS VENTURE
Fair playing time
without the spreadsheet.
Smart Sub Saver helps junior and grassroots sports coaches plan substitutions, track playing time and manage fairer rotations while they focus on coaching the game.
Keep coaching the game.
Match day asks one coach to watch the game, remember every change, account for availability and roles, work out the next substitution and make sure no child is left on the sideline for too long. Smart Sub Saver removes much of that mental calculation without taking away the coach's judgement.
CURRENT STATUS
Focused, coach-first and nearing commercial validation.
Smart Sub Saver is the most mature Ex Parvis venture. The priority is still validation before expansion: prove the core match-day workflow, learn from coaches and resist turning a focused tool into an untested all-purpose sports platform.
PRODUCT CAPABILITY
One match-day workflow.
During the game
Track match time and player minutes, receive substitution guidance and adapt the rotation while retaining coach control.
After the game
Review playing-time distribution, retain match history and share clearer participation information with parents.
PLANNING THAT FITS THE GAME
Fairness has more than one shape.
Practical fairness
Balance meaningful playing time without pretending every match can follow a perfect mathematical plan.
Balanced workload
Use player roles, availability and match requirements to distribute the demands of the game more thoughtfully.
Fewer interruptions
Plan smaller group changes or less frequent substitutions when match flow matters more than exact-time targets.
Coach control
Recommendations support the coach. They do not remove the ability to respond when the match changes.
