The short answer

GroupTalk is push to talk software where a crew member talks to a whole workgroup at once [1]. GroupTalk's page says its push to talk and personal alarm features enable secure, real time communication across all personnel and workgroups [1], and that its cloud based system offers unlimited range [1]. Voxer's Personal plan is free for individuals [2]. Voxer also offers a 14 day free trial for business [3]. For a crane crew member, GroupTalk's sources say it meets the need to keep separate groups for different roles, functions, areas or tasks [1] and to raise a personal alarm to nearby colleagues and central management [1]. Voxer's sources say it meets the need to build groups by syncing Procore contacts [6].

What GroupTalk, Voxer is built for

GroupTalk's page says its push to talk and personal alarm features enable secure, real time communication across all personnel and workgroups [1]. Separate push to talk groups can be set up for different roles, functions, areas or tasks [1]. Its cloud based system offers unlimited range and secure communication [1], and group voice channels allow simultaneous communication across multiple teams [1]. Personal alarms report incidents immediately to nearby colleagues and central management [1], and lone workers can alert nearby colleagues and central resources immediately [1]. The page says it integrates live location tracking, alarms and group communication for construction sites to support effective HSE procedures [1], and that supervisors and managers can reach any team or individual instantly [1]. It names NCC, Entry, Veidekke and YIT as construction companies that chose it [1]. It also offers private cloud and on premises deployment [5]. Voxer's page offers a 14 day free trial for business [3], syncs Procore contacts to create groups [6], and has a personal plan that is free for individuals [2].

What OperatorLink is built for

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 [4]. It runs in a phone browser with no app install [4]. STOP releases every held direction on every phone and shows a full screen alert to everyone else [4]. HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves [4]. Holding a move button keeps sending that move to the other phones; if it stops arriving for 2 seconds, they drop it [4]. One tap radio style calls such as Go Ahead, Copy That and All Clear go out as chat messages [4]. Anyone who joins can take part in a voice call run from the phone browser [4]. Button presses, chat and voice pass between phones in a browser [4].

Pricing and fees

GroupTalk does not publish a price on its page; it offers a 14 day free trial [5] and a sales contact [1]. What it costs after the trial is not published, so the price comes from talking to sales. Voxer's personal plan is free for individuals [2], and business use starts with a 14 day free trial [3]; Voxer does not publish a business price on its page either. OperatorLink is currently free to use, and no paid plan is built yet [4]. None of the three is a card payment service, so no card payment fee applies and none is published.

Setting it up on a jobsite

GroupTalk needs separate push to talk groups to be set up for different roles, functions, areas or tasks [1], and its group voice channels carry simultaneous communication across multiple teams [1]. Its page says supervisors and managers can reach any team or individual instantly [1]. Voxer builds groups by syncing Procore contacts [6]. OperatorLink is started by one person who shares a link or QR code, and the crew joins from it [4]. A jobsite link stops working 12 hours after the first person joins [4], and a jobsite with nobody in it is wiped after 3 idle hours [4]. The tool can be added to a phone's home screen as a standalone app [4]. On Android browsers signals such as STOP make the phone buzz, while iPhone Safari ignores the buzz [4].

Things to check before you choose

What does the tool cost after the free trial ends, and does the price match the size of the jobsite crew? Does the crew's signal procedure match how STOP, HOLD and SLOW behave on the tool? What does a voice call depend on from the phone network at the jobsite? If lone worker alerts matter, how does a personal alarm reach nearby colleagues and central management? How are groups kept separate for different roles, functions, areas or tasks? What happens to a signal when a phone drops off? If the crew already logs work in Procore, does the tool build groups from those contacts?

How to choose

If the crew needs separate groups for different roles, functions, areas or tasks with live location and personal alarms, GroupTalk's sources say it offers those [1][1][1]. If the crew already works in Procore and wants groups built from those contacts, Voxer's sources say it syncs Procore contacts [6]. If the crew wants STOP, HOLD and SLOW shown to everyone in the jobsite with no app install, OperatorLink shows those signals and passes button presses, chat and voice between phones in a browser [4][4][4]. Confirm the price after any trial before committing, since GroupTalk and Voxer do not publish one.

Frequently asked questions

Is GroupTalk free?

GroupTalk's page does not publish a price. It offers a 14 day free trial [5] and a sales contact [1], so what it costs after the trial is not published. Anyone comparing it for a crane crew should ask sales for a price before choosing, since the free trial may not line up with the size of the jobsite.

Is Voxer free?

Voxer's personal plan is free for individuals [2]. For business use it offers a 14 day free trial [3], and it does not publish a business price on its page. A crane crew member who wants Voxer for work should treat it as a trial first and check the price after the trial ends.

Does OperatorLink need an app install?

OperatorLink runs in a phone browser with no app install [4]. It can also be added to a phone's home screen as a standalone app [4]. The crew joins when the person who starts a jobsite shares a link or QR code [4].

What does the OperatorLink STOP signal do?

OperatorLink shows STOP, HOLD and SLOW to the jobsite crew [4]. The STOP signal releases every held direction on every phone and shows a full screen alert to everyone else [4]. A crane crew member should still match this to the crew's own signal procedure before relying on it on a jobsite.

Does Voxer work with Procore?

Voxer's page says its contacts can be synced with Procore to create groups [6]. So a crane crew that already logs its work in Procore can build Voxer groups from those contacts. Voxer also offers a 14 day free trial for business [3] and a personal plan that is free for individuals [2].

OperatorLink is currently free to use, and no paid plan is built yet. [4]
