What you need before you start

The person who starts the jobsite needs a list of the phones the crew will join from, a working phone browser, and a clear plan of who controls the signal. Each signal person and rigger should have their own phone with a browser and a full charge, because joining happens from a phone browser. [1] Decide in advance who shares the link, because that person holds the start link and sends it out. Agree on the meaning of each signal and move before anyone joins, so the words mean the same to everyone. Confirm that every crew member can open the shared link or scan a QR code, because that is how people join. [1] Make sure the phones have a data or wifi connection, because the signals pass between phones and no claim says this works without a signal. Check that every phone browser can open the link and show a full-screen alert, since STOP shows a full-screen alert to everyone else. [1] Agree on what to do if a phone drops out, because a move is dropped after 2 seconds if it stops arriving. [1] Keep a backup way to talk, such as a radio, and check how any tool you pick behaves when a connection fails.

Step by step

  1. Choose the tool and the person who starts the jobsite. That person opens the tool, starts a jobsite, and keeps the link or QR code ready. [1]
  1. Send the link or QR code to every signal person and rigger before the lift. Send it by text or show the QR code so each person opens it on their own phone.
  1. Have each crew member join from a phone browser and confirm they see the same jobsite and the other people on it. [1]
  1. Agree on the signals and who sends them. If the tool has move buttons, decide who holds STOP, HOLD and SLOW and how moves are sent.
  1. Run a short check before work starts: one person sends a stop and everyone confirms they see it, because STOP releases every held direction and shows a full-screen alert. [1]
  1. If the tool offers chat and voice, have one person send a quick message and join a call, so the crew knows how to talk without leaving the link. [1] [1]
  1. Confirm how the jobsite ends. Check how long a link stays live and when an empty jobsite is wiped, and tell the crew, so nobody is surprised. [1] [1]
  1. Agree on a fallback and who keeps the link safe. Check how any tool you use handles a phone that drops out.

Tools that can do it

OperatorLink is made by the team that publishes this site. It shows STOP, HOLD and SLOW to the jobsite crew, and passes button presses, chat and voice between phones in a phone browser. [1] One person shares a link or QR code and the crew joins from it. [1] STOP releases every held direction on every phone and shows a full-screen alert to everyone else. [1] HOLD and SLOW stay on for everyone and are cleared when the last person leaves. [1] Holding a move button keeps sending that move, and the other phones drop it if it stops arriving for 2 seconds. [1] One tap sends radio-style calls such as Go Ahead, Copy That and All Clear as chat messages. [1] Anyone who joins can take part in a voice call run from the phone browser. [1] The app runs in a phone browser with no app install, and it can be added to a phone's home screen. [1] [1] A jobsite link stops working 12 hours after the first person joins, and an empty jobsite is wiped after 3 idle hours. [1] [1] STOP makes the phone buzz on Android browsers, while iPhone Safari ignores the buzz. [1] OperatorLink is currently free to use, with no paid plan built yet. [1]

Other tools can send messages and signals between phones, but no published facts are listed here for them, so check each one's own material for what a crew gets, how people join, and what it charges. When a source does not state a fee, treat the fee as not published and ask the provider before relying on a free claim. Check how long a link stays live and whether a signal is dropped on a weak connection, because no claim covers those for tools not listed here.

Common mistakes to avoid

Start work only after agreeing who controls the signal, or two people may send moves at once. Tell the crew when a link expires, because a jobsite link stops working 12 hours after the first person joins. [1] Do not leave a jobsite open and unused, because an empty jobsite is wiped after 3 idle hours. [1] Watch for a phone that drops a move, since moves are dropped after 2 seconds when they stop arriving. [1] Do not count on an iPhone buzzing for a signal, because iPhone Safari ignores the buzz. [1] Do not assume the tool works without a connection, because no claim says it does. Keep a backup talk channel such as a radio, and name who uses it if a phone fails.

Frequently asked questions

How does the crew join one jobsite link?

One person starts a jobsite and shares a link or QR code, and each crew member joins from it on a phone browser. [1] [1] Before the lift, have every signal person and rigger open the same link on their own phone and check that they see the same jobsite. For other tools, check the provider's material for how the crew joins.

Is OperatorLink free?

OperatorLink is currently free to use, and no paid plan is built yet. [1] It runs in a phone browser with no app install. [1] Because the price could change, check the product's own page before relying on the free claim. For other tools, read the provider's fee terms, and if no fee is stated, ask the provider what it charges.

How long does a jobsite link stay active?

A jobsite link stops working 12 hours after the first person joins it. [1] If you plan a long job or a job that runs across a break, start a fresh jobsite when the link is near its limit. An empty jobsite is wiped after 3 idle hours. [1] For other tools, check the provider's material for how long a link stays live.

What happens if a phone drops a signal?

Holding a move button keeps sending that move to the other phones, and they drop it if it stops arriving for 2 seconds. [1] So a weak connection can end a move, and the crew should agree on a backup talk channel such as a radio. No claim says any tool keeps working without a phone signal, so check the provider's material for what happens on a weak connection.

Does every phone buzz when a signal arrives?

On Android browsers, signals such as STOP make the phone buzz, while iPhone Safari ignores the buzz. [1] So on iPhones the crew relies on the full-screen alert, not a buzz. Everyone should confirm they see the alert before starting a lift. For other tools, check the provider's material for how alerts appear on each phone.
