Sub iQ: Sub Timer & Rotation

Fair playing time for every kid. Timed subs for every game.

Sub iQ is the substitution app for junior sport coaches. It builds a fair line-up, plans your subs before kick-off, times every substitution wave on the sideline and tracks each player's minutes across the season. Made for youth soccer coaches first, then built out for field hockey, water polo and basketball, with a custom sport for anything else.

You make the calls. Sub iQ does the maths.

WHY COACHES USE IT
Equal playing time is the promise every junior club makes and the hardest thing to deliver on game day. Sub iQ is a sub timer, rotation planner and minutes tracker in one, so you can watch the game instead of the clock.

BUILD YOUR LINE-UP
• Lineup maker with a drag-and-drop formation builder
• Set positions, a goalkeeper and who can cover where
• Starters chosen on season minutes, so the same kids are not always on the bench
• Late arrivals, injuries and borrowed players handled before kick-off

PLAN YOUR SUBS
• A substitution plan with projected minutes for every player
• Fairness scores, so you see how the plan lands before the whistle
• Rolling subs or a sub limit, halves or quarters, set per sport
• Share the match plan with your assistant coach as a PDF

LIVE ON THE SIDELINE
• Game clock with periods, breaks and a countdown to the next fair sub
• Suggested sub waves: who comes off, who goes on, confirmed with one tap
• Live field view with the bench, positions and minutes played
• Goalkeeper rotation, sin bins, yellow and red cards, early finishes
• Log goals and keep score

TRACK THE SEASON
• Season planner that evens out playing time over every round
• Minutes, starts, goalie time and positions for each player
• Leaderboards plus pair, trio and quad chemistry
• Season plan and season stats as PDFs for parents and the committee

EVERY SPORT, PLAYED PROPERLY
Each sport gets its own rules, words and surface, so it feels built for your game.

JUNIOR SOCCER (FOOTBALL)
• Small-sided to 11-a-side, halves or quarters, 20-minute halves by default
• Formations such as GK + 2-3-1 or GK + 4-3-3 on a real pitch
• Dedicated or rotating goalkeeper, with keeper time counted fairly
• A substitution limit for competitions that cap subs, with a check before you go over
• Yellow and red cards, and the plan reshapes itself after a send-off
• Stints of at least 5 minutes, so no kid is on and off in a flash

FIELD HOCKEY
• 7-a-side junior and full-pitch formats, four 10-minute quarters by default
• Rolling substitutions from the bench, as many as the game needs
• Green and yellow cards run their own sin-bin timers (2 and 5 minutes) and the plan adjusts around them

WATER POLO
• One goalie and six in the pool, four 8-minute quarters by default
• Rolling subs with short stints for swimmers who tire fast
• Cap numbers on every player card, pool positions and keeper rotation

BASKETBALL
• 5 on court, four 8-minute quarters, rotations at dead balls
• Point guard to centre on a real court, with fair minutes across every quarter
• Log points, keep score and keep the whole bench in the game

CUSTOM SPORT
• Set players on field, periods, period length and whether subs roll or are limited
• Name your positions and build a formation for futsal, touch football or any team game with a bench
