Accept once.
Blocked everywhere.

REF CLASH keeps your availability in sync across every assigning platform. Take a game on one site and that time is automatically blocked on all the others. No more double-bookings. No more copy-pasting your schedule.

The problem

Too many platforms.
One referee.
Zero sync.

Every assignor uses a different scheduling site, and none of them talk to each other. So every time you accept a game, you're stuck doing the same chore over and over.

✕Accept a game on one site, then log in to three others to block the same time slot.
✕Forget one, and an assignor books you for a game you can't make.
✕Turn back a game last minute, and it hurts your standing with the assignor.
✕Spend your Sunday nights on calendar admin instead of resting up.

How it works

Set it up once. Done.

Three steps and REF CLASH handles the rest.

1

Connect your accounts

Link the assigning platforms you already use. It takes about two minutes.

2

Accept games like normal

Keep using each platform the way you always do. Nothing changes on your end.

3

We block the rest

REF CLASH spots the new game and blocks that time everywhere else, including travel buffers.

Platforms

Works where you work

We started with the sites NY-area referees use most, and we're adding more every season.

Planned

Built for refs

Smart about game day

Knows how long games run

Block length matches the age group, so a U10 game doesn't eat your whole morning and a U17 game isn't cut short.

Buffers built in

Adds time before and after each game to cover travel, check-in and paperwork.

Merges back-to-back games

Three games in a row on the same field? You get one clean block, not three separate ones.

Made for your phone

Add it to your home screen on iPhone or Android. It works like an app, with nothing to download.

"I got tired of blocking the same Saturday on four different websites. So I built the fix."

FAQ

Straight answers

Is it free?

Yes. REF CLASH is free while it's in beta.

How do I get in?

The beta is invite-only for now. If you have an invite code, sign up at app.refclash.com/signup. If you don't, reach out and we'll add you to the list.

Is my login information safe?

Where a platform supports it, you log in through that platform's own sign-in page, so we never see your password. For platforms without that option, your credentials are encrypted and used only to manage your availability. You can ask us to delete your data at any time.

Will it accept or decline games for me?

No. You stay in control of which games you take. REF CLASH only blocks your time on the other platforms so nobody books you twice.

Which platforms does it work with?

REF CLASH works with several of the most popular referee assigning sites, and more are added each season. Sign in to see the current list.

Is REF CLASH affiliated with any assigning platform?

No. REF CLASH is an independent tool built by a referee, and isn't endorsed by or affiliated with any assigning platform.
