REF CLASH keeps your availability in sync across every assigning platform. Take a game on one site and that time is blocked on all the others. No more double-bookings. No more copy-pasting your schedule.
Free during beta · Works on any phone · No app store needed
Sign up, connect your platforms, run a check, and confirm your blocks. Here's the whole thing, start to finish.
Sound on 🔊 · Platform names and games shown are examples.
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.
Four steps, and REF CLASH handles the rest.
Enter your name, email and invite code. Your personal dashboard link is your sign-in. Add it to your home screen.
Link the assigning sites you already use. It takes about two minutes.
Keep using each platform the way you always do. REF CLASH checks every morning and evening, or whenever you tap Run Check Now.
See exactly what will be blocked, untick anything you don't want, and confirm. The time is blocked everywhere else, buffers included.
We started with the sites NY-area referees use most, and we're adding more every season.

PLANNEDSee all your accepted games from every platform in one place, soonest first. Need time off? Add a manual block and it goes on all your platforms at once.
Block length matches the age group, so a U10 game doesn't eat your whole morning and a U17 game isn't cut short.
Adds time before and after each game to cover travel, check-in and paperwork.
Three games in a row? You get one clean block, not three separate ones. It works across platforms too.
Four tabs along the bottom: Blocks, Platforms, Schedule and Help. Add it to your home screen, with nothing to download.
See exactly what REF CLASH wants to add, untick anything you don't want, then confirm.
Automatic checks every morning and evening, plus a button to check right now.
When you give a game back, REF CLASH removes the block it made, where the platform allows it.

Every check lists the blocks for you to tick and confirm. Plus the Upcoming games list, and a third platform open to everyone.
Games from it block your other platforms and the other way around. It is being switched on for referees step by step.
A cleaner app with tabs along the bottom, a Help tab to reach us, faster pages, and a way to get your link back by email.
Block a trip, a class or a shift yourself, and it goes on all your platforms at once.

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

The beta is invite-only for now. If you have an invite code, sign up at app.refclash.com/signup. If you don't, email [email protected] and we'll add you to the list.
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.
You can. The list of your upcoming games is yours. If you ask for help with a problem, the person running REF CLASH can look at your dashboard and your upcoming games, read only and without game locations. Passwords and logins are never shown to anyone.
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.
REF CLASH removes the block it created for that game, where the platform allows it, and tells you what it removed. Blocks you made yourself are never touched.
Yes. On the Schedule tab, add a manual block for a single day or a range of days, all day or part of the day. Confirm once and it's blocked on all your platforms. You can remove it any time.
Go to app.refclash.com, type the email you signed up with, and we'll email your link to you again.
