Why Siren
Built for the kid who's been stuck in the same spot all quarter.
The sideline tool that tracks where every kid has played, not just how long they've been on.
The sideline reality
Three minutes until the next whistle.
You're coaching the U10s. Marcus has been pinned in the same spot all quarter. Chloe just rolled in late. Your shooter (or full-forward, depending which sport you're reading this on) needs a spell. Jasper's dad is yelling from the boundary that his son hasn't had a go in the middle all game.
You've got a whistle in one hand, a clipboard in the other, and three minutes until the next break.
Sound familiar?
The difference
Positions, not just minutes.
A generic sports app can count minutes. But in junior sport, fair isn't about how long a kid's been on. It's about whether they've had a crack at every part of the game.
Siren tracks time per position area: attack, centre, defence, and bench. Football coaches see forward, centre, back, interchange. Netball coaches see attack third, centre third, defence third, bench. When the rotation suggester runs, it doesn't just look at who's played the least — it looks at who's missed out on where. The kid who spent the whole first quarter at full-back (or stuck at goal keeper) gets their run up front before the final siren.
This is how fairness in junior sport actually works.
Time per area
48 min gameFollowing your league's junior rotation policy (rotate every quarter, several positions, 50–75% minimum game time) turns out to be a nice side effect. The point is that every kid leaves the ground feeling like they got a go.
Built for our game
Not a generic rotation tracker.
Junior football and netball have their own rhythms. Quarters, not halves. Position areas the kids actually recognise — attack/centre/back for football, three thirds with seven bibs for netball. The “everyone gets a go” ethos. Fixtures via PlayHQ. Lending a kid to the opposition when numbers are uneven. Mid-quarter subs when your league allows them, period-break subs when it doesn't. Siren is shaped around those things, not adapted from a soccer subs app.
A note from the coach who built it
I built Siren because I got sick of juggling a clipboard on the sideline and couldn't find a tool built properly for our game. I'm a parent-coach in Australia, not a SaaS company.
Siren is free for the entire 2026 season. No trial timer, no paywall, no upsell. I'm using this season to learn from the coaches using it and make it better week by week. Clubs who get on board now will be looked after when paid options arrive.
If you want to be the coach whose kids all remember getting a go, I'd love your help shaping it.
