Junior rugby league · quarters, then halves from Under 10
Rolling subs, First Receiver and Dummy Half vests, kicks shared round, and every kid's unbroken period. Siren knows the Junior Laws that generic sub-timers miss, so you can stop juggling a clipboard and watch your kid play.
What Siren knows
FR · DH
First Receiver and Dummy Half move round the team each period, and no kid wears either twice.
Unbroken
Under 10 to Under 12, every kid plays at least one unbroken half; younger teams get two unbroken quarters.
4 + 2
A try is 4 and a conversion 2, and the kicks are shared round so everyone gets a shot at goal.
The rotation engine tracks minutes for all players and nudges you toward balanced playing time, without you having to count.
Log a try with one tap; the conversion kicker comes from the rotation. Every player kicks before any kicks twice (with a one-tap override for the rare double). Turn scoring off if you're in an age group that does not keep score.
At U9 and up, the FR and DH vests rotate every period. Siren tracks who's worn what across the match so no player wears a vest twice and handles the injury-replacement carve-out without breaking the count.
Mark each player available or unavailable the night before. Short of numbers? Drop the on-field count to match and Siren rebalances rotations + vest assignments automatically.
Tap any player, then Player actions, to lock them to forward or back, flag an injury, or lend them to the opposition. Siren adapts mid-game without losing track of the rotation or the vest plan.
Big Jimmy's a tackling machine? Little Lenny's a speedster out wide? Add forward / back position chips to start introducing the concept of positions to players. The lineup suggester routes chipped players to their position first, then balances the rest.
At half-time, Siren suggests a reshuffle that balances forward/back time, keeps every player's unbroken periods on track, and rotates the FR/DH vests. One tap to accept, or tap two players to switch them.
Send the run-link to a parent on the sideline and they become the scorer for the day. No app download, no account, no setup. A magic link gets them straight in.
Did you know that the junior rules dictate that every player must play an unbroken half or quarter regardless of how many players you have on the bench? Neither did we. Abide by the official rules or have flexibility to run your squad the way you want.
After every game, field-time and vest-wear stats update automatically. Spot who hasn't had a chance with a vest and fix it before next round.
