Everything Ultimate Clock does

Every feature at a glance. Then the guide walks you through it step by step.

On the field

Game clock with global pause

The game clock, halftime and a ❚❚ button that stops every running clock at once.

Automatic pull

When a team scores, the pull countdown starts by itself and shows which team throws. Whistles at 45, 60, 75 and 90 s.

Time outs with a quota

Each team sees how many it has left, and the quota resets in the second half.

Eight call types

Foul, violation, pick, travel, stall, contested goal, injury and spirit timeout, each one explained.

Goals with assist and scorer

One tap adds the goal; then pick who assisted and who scored. Undo if it was a mistake.

WFDF, USA Ultimate or your own

Rule sets with times already loaded, or a profile of your own.

To run a tournament

Teams from Excel

Download the template, fill in teams, players and colors, then import it. Up to 64 teams.

Team logos

They show on the board, the fixture and the live link.

League or brackets

Round robin or knockout, with a bracket view and a champion.

Standings and stats

Table, scorers and assists per player; points and tiebreakers are adjustable.

Several devices at once

One table per field with the same user; if a phone fails, pick up from another.

Fixable results

Made a mistake? Correct it and the fixture, the advancing winner and the table update by themselves.

To share

Live link

The crowd follows score, clock, play-by-play feed and standings on their phones, nothing to install.

Scoresheet as PDF, CSV or WhatsApp

Export the game to print, to open in a spreadsheet or to send to the group chat.

Your tournament in a file

Export and import the tournament between devices.

In your pocket

Sound and screen kept on

Loud alarms for every countdown, and the screen stays on during the game.

Light or dark

Light mode for the sun, dark for the night.

Spanish and English

Switch the language from the menu.

Installable, works without signal

Add it to your home screen. If the internet drops it keeps recording and syncs when it is back.

New

New: run your tournament with your AI

Connect Ultimate Clock to your AI assistant and ask for things in your own words. It only sees and touches the tournaments of your account.

It can also add or remove players, upload logos, set the times and delete a tournament (it asks for the exact name). You can disconnect the AI any time from the site.

  1. Add the connector

    In your AI assistant (with MCP connectors) add a connector with this address:

    https://iona.ar/ultimateclock/api/mcp
  2. Sign in once

    An Ultimate Clock page opens for your username and password. The AI never sees your password.

  3. Ask for what you need

    Try one of these requests:

    • “Create the Spring Cup tournament with 6 teams and build a round-robin fixture.”
    • “Enter the result Hawks 9 – Foxes 7, with Ana’s goals.”
    • “How is the table and who are the top scorers?”
    • “Give me the live link to send to the group.”

The guide, feature by feature

Everything the app does, with real screenshots. As you scroll, the screenshot changes with each step.

Everything fits on one screen, top to bottom: the game clock, the teams with their score, each team's call timer, the pull and the time outs.

  • Start starts the clock; below it you see time left and time to halftime.

The only clock that pauses is the game clock. Pull, call, time out and halftime run until they finish.

Pull and time outs

When a team scores, that team’s pull starts by itself (you can also start it by hand): whistles sound at 45, 60 and 75 seconds, and the fourth at 90, when time is up.

  • If play has to stop, ❚❚ PAUSE in the top bar stops every clock; ▶ RESUME starts them again.
  • Each team button shows its remaining time outs (for example 2/2); in the second half the allowance renews.
  • When the first half ends the clock stops and a halftime prompt appears.
