You coach. We'll fill in the blanks.

You've got twelve kids, nine spots, and a parent in a lawn chair keeping track. Most of us end up doing it on a legal pad at ten o'clock the night before, and we still can't tell you who's played the least infield this year.

That's the whole job READY does.

What "fair" actually means here

Not a slogan. These are the rules it follows on every single lineup:

Nobody sits twice until everybody has sat once. And if your roster is big enough that it can't manage that, it tells you instead of hiding it.
Infield and outfield even out over the season, not just over today's game. Most apps forget by Saturday.
No kid parked in the same spot two innings running, unless there's no legal way left to fill the field.
If you say a kid never catches, they never catch. A lockout is a rule, not a warning you can click past at 10pm. READY never overrides one to make the math easier. Not once.
Every inning counts from game one to the last game. That's why fair in October depends on what happened back in May.

Here's the proof, from its own engine

I ran a full twenty-game season two ways. Both coaches gave every kid the exact same innings — 90 apiece, dead even. The difference is where those kids stood.

Gap between the most and least infield innings, over one season

Rotating the bench down the roster, the way we all do it

Same roster, same games, run through READY

Same twelve kids, same twenty games, same innings for everybody. Full write-up and the per-player numbers are in Equal innings isn't the same as being fair.

Built to fit your league, not the other way around

Baseball and softball. Tee-ball, coach pitch, kid pitch.
No roster cap, no team cap. Bring sixteen kids. Bring eighteen. Coach two teams on one subscription. Big rosters are exactly where fair rotation is hardest and matters most.
1 to 12 innings a game, whatever your league plays.
Optional 5th infielder and a rover or short fielder, if that's how you line up.
One product, every age. Tee-ball through 14U get the same rotation, the same lockouts for any position, and the same rule switches. Nothing to choose, nothing to outgrow.
Pitcher and catcher holds, catch-after-pitch protection, and the mound re-entry rule for the leagues that use it — all switches you control, not assumptions we made for you.
A kid doesn't show up? Uncheck them and the rotation fixes itself. You don't rebuild anything.
Swapped somebody mid-game? Fix the record afterward so your season totals stay honest.

Why I built it

I coach youth baseball in Livermore, California. I built this because I got tired of doing rotations on a legal pad at 10pm and still not being able to answer a parent who asked why their kid hadn't played infield in three weeks.

I wasn't trying to start a company. I needed the thing to exist for my own team. Everything in it is there because it came up at a real field, in a real season, usually the hard way.

Before you pick any lineup app, ask it these five things

Genuinely — go ask these of whatever else you're looking at. They're the questions that separate a lineup app from a rotation you can defend.

If I say a kid never pitches, will it actually obey me — or just warn me?

There's an app out there that calls its rules "guardrails, not hard blocks" and leaves the final call to you — which sounds generous until it's the fourth inning and you're busy. READY treats a lockout as a rule. It never overrides one, even when obeying it makes the rotation harder to solve. This is the big one.

What does it cost me a year?

There's a lineup app charging $39.99 a season, or $7.99 a month — for a team you coach for free. READY is $9.99 a year, for as many seasons and as many teams as you coach. Your first three lineups are free, no card, so you see it work before you decide.

Does it count across the whole season — for every kid, or just a few?

Most build a good lineup for today and forget it by Saturday. One that does keep count shows you a handful of kids' numbers and blurs the rest until you subscribe. READY carries every inning forward all season, and every kid's totals are yours from the first free lineup. The numbers above show why that matters.

Does it stop the same kid living in right field?

This is the complaint coaches actually get. Nobody says "my kid didn't get enough innings" — they say "my kid always plays right field." READY counts infield and outfield innings as their own thing and weighs them above everything except bench time, across the whole season. Season Totals shows each kid's IF and OF columns, so you can see it balance rather than take my word for it.

Does it cap how many kids I can have?

Some do, as low as 14. READY has no cap on players and no cap on teams.

Does it work at the field, with one bar of signal?

READY builds the rotation on your phone — no server, no spinner, no "retry rule check." The sheet is a real PDF, one tap, printable with no signal at all.

Every rule on this page is one the app actually enforces — and where a rule is best-effort rather than guaranteed, it says so above instead of promising something the math can't always deliver. The season comparison was run through the same rotation engine the app ships with.
