Install Opsler on Any Device — Straight From Your Browser

There is no app store download and no IT ticket. Open Opsler in the browser you already use, run that browser’s install command, and it sits on the home screen or dock with its own icon. Below: the current steps for each device, and the one extra step that prepares a technician’s phone for a house with no signal.

Install Opsler on Any Device: The Quick Answer

Most people who set out to install field service app software open the App Store or Google Play first. Opsler is in neither, and doesn’t need to be. You open it in the browser already sitting on the device, use that browser’s own install command, and Opsler lands on the home screen or dock with its own icon — its own window, no tabs, no address bar eating a strip of a screen your technician is already squinting at.

That is how you install Opsler app on any device: a Windows or Mac computer, an Android phone, an iPhone. Sign in, run the command, confirm the prompt. Everything below is where each browser maker hides that command, because they all hide it somewhere different.

One thing to settle before the steps. Installing puts Opsler on the device. It does not put today’s work on the device. That is a second, deliberate action inside the Field Agent App, and skipping it is how a technician ends up holding a phone with an Opsler icon on it and nothing behind the icon, in a crawl space, at 8am.

Open Opsler and install it

Choose Your Device and Supported Browser

Opsler runs in any current browser. This table answers the narrower question of which ones can also install it to a home screen or dock. The last row is the one that generates support tickets: on an iPhone the install step belongs to Safari alone, so a technician who lives in Chrome has to open Opsler in Safari once — just the once — to get the icon.

Device	Browser	Installs	Where the command lives
Windows laptop or desktop	Chrome	Yes	Install icon in the address bar, or the three-dot menu
Windows laptop or desktop	Edge	Yes	Settings and more → More tools → Apps
Mac laptop or desktop	Chrome	Yes	Same three-dot menu as Windows
Mac laptop or desktop	Safari	Yes	File → Add to Dock, on macOS Sonoma and later
Android phone or tablet	Chrome	Yes	Three-dot menu → Install and create shortcut
iPhone or iPad	Safari	Yes	Share → Add to Home Screen. Safari only
iPhone or iPad	Chrome or Firefox	Use Safari	Opsler runs fine, but iOS keeps the install step in Safari

Install Opsler on Desktop or Laptop

You install Opsler on laptop and desktop machines exactly the same way — what decides the steps is the browser, not the computer. Sign in to Opsler first; most browsers will not offer the install command while you are still sitting on the sign-in screen.

Chrome, on Windows or Mac

Look at the right-hand end of the address bar and select Install.
If that icon isn’t showing, open the three-dot menu, choose Cast, save, and share, then Install page as app.
Confirm the prompt. Opsler appears in your Start menu, Applications folder or dock.

Edge, on Windows or Mac

Open Settings and more, then More tools, then Apps, then Install this site as an app.
Confirm the prompt, and Opsler is installed alongside your other apps.

Safari, on a Mac

Choose File then Add to Dock from the menu bar, or use the Share button in the toolbar and choose Add to Dock.
Type the name you want, then click Add.
Opsler is saved to the Applications folder in your home folder, and opens from the Dock or Spotlight. This needs macOS Sonoma or later.

Menu labels above are the current wording in each vendor’s own help documentation, read 4 August 2026. Browser makers rename these items more often than you would expect — if a name has moved, look for whichever item mentions installing or adding to the dock.

Install Opsler on Android

Chrome is the shortest path on an Android phone or tablet, and it is the one worth standardising on if you are setting up a crew’s handsets in one sitting.

Open Opsler in Chrome and sign in.
Tap the three-dot menu to the right of the address bar.
Tap Install and create shortcut, then Install.
The Opsler icon appears on the home screen and in the app drawer.

Open it from that icon rather than from Chrome afterwards. Launched from the icon, Opsler fills the screen and drops the browser furniture; launched from a Chrome tab, it is still Opsler, just with less room to work in and a tab that is easy to lose behind twelve others.

Android is also where a shared or hand-me-down handset causes trouble: install under the technician who will actually carry the phone, and have them sign in as themselves, or the Field Agent App will show somebody else’s day.

Install Opsler on iPhone

This one has to be Safari. Chrome and Firefox run Opsler perfectly well on an iPhone or iPad, but neither exposes the install step — iOS keeps it in Safari’s Share sheet. If your technician normally lives in Chrome, that is fine; they just need to open Opsler in Safari once to get the icon, and can go back to Chrome for everything else afterwards.

Open Opsler in Safari and sign in.
Tap the Share button. Depending on where your tab bar sits, you may need to tap the menu button first.
Scroll the list and tap Add to Home Screen. If it isn’t there, scroll to the bottom, tap Edit Actions and add it.
Name it and tap Add. The icon lands on the home screen.

There is no Opsler listing in the App Store, so searching for one is a dead end. If a technician reports that they “can’t find the app”, this is almost always what happened — send them the Opsler web address and the four steps above instead.

Launch, Pin or Remove Opsler

Launching. Tap the Opsler icon like any other app. It opens in its own window rather than a browser tab. On a Mac, a Safari web app keeps its sign-in separate from the browser, so the first launch may ask a user to sign in once more even though they were already signed in in Safari.

Pinning. On Windows, right-click the Opsler icon in the taskbar and pin it. On a Mac, right-click it in the dock and choose Keep in Dock. On a phone, drag the icon wherever the technician actually looks — usually the bottom row, next to the phone dialler they use forty times a day.

Removing. Remove it the way you remove any app on that device: uninstall from the Start menu or dock, or press and hold the icon on a phone and delete it. Nothing in your Opsler account changes — you are removing an icon and the copy of your data held on that handset, not the account or its records. Signing back in through the browser puts everything back. This is the right move when a technician leaves and hands the phone in.

Updates. There aren’t any to install. No app-store review queue, no separate iPhone and Android versions drifting apart, no technician running something six versions old because they never tapped update. Everyone is on the current version because there is only one.

Prepare the Field Agent App for Offline Work

Installing is the easy half. The half people skip is the one that lets a technician actually use Opsler offline, and it is a short trip: in the Field Agent App, open More, tap the Offline Sync card, and on the screen that opens — titled Sync for Offline — tap Sync Now. After the first run that button is labelled Refresh Sync.

Do it while you still have signal, in the yard or on the driveway. The screen works through its steps one at a time and ticks each off as it lands, so you can watch it rather than hope:

Today's Jobs
Parts Catalog
Service Catalog
Tax Settings
Van Location
Stock Levels
Customer History

When it finishes, a Cached Data panel gives you counts for what is now on the phone: jobs, parts, services, stock levels and how many customers’ histories came down. The screen also shows when it last ran. Check those counts before driving off — a sync that reports zero jobs is telling you something useful while you can still do something about it. Make it part of the morning routine, in the same breath as loading the van.

Two limits worth knowing before you rely on this rather than after. You have to be online to run it — the button is disabled with no connection, which is exactly when someone thinks to look for it. And a job the office adds after the technician synced will not be on the phone until that phone next has signal.

What Works Offline — and What Still Needs Connectivity

Taking a field service app offline is a different question from installing one, and it deserves a straight answer per action rather than per screen. Most of it works exactly the way it does online — nine of the fourteen rows below need no connection at all. Four rows do: real limits, not gaps we would rather you found later.

Read the two estimate rows together. Building a Good/Better/Best estimate with no signal works and the draft is safe on the device. Submitting a brand-new one is the exception on this page: nothing carries it to the office on its own, so it waits as a draft until the technician reopens it with a connection. Invoices behave the way people assume estimates do — they queue and go up by themselves — and that difference matters if a customer is standing there waiting for a number.

Task	With no signal	Detail
Open today's job list	Works	Downloaded by Sync for Offline before you leave
Read a customer's history at that address	Works	Comes down with the job set
Look up a part or a service and its price	Works	Both catalogs are held on the device
Check van stock levels	Works	Held for lookup; the number shown is as of your last sync
Change job status — On My Way, Arrived, Start, Pause, Complete	Works	Held in order and replayed when the phone reconnects
Tick checklist items and add notes	Works	Each tick stamped with who did it and when
Take before-and-after photos	Works	Kept on the device, uploaded on reconnect
Draft a Good/Better/Best estimate	Works	Autosaves to the handset line by line, and is still there when the form reopens
Submit that new estimate to the office	Needs signal	Nothing carries a brand-new estimate out on its own — it waits as a draft until the technician reopens it with a connection and sends it
Build an invoice, take a signature, collect payment	Works	Held on the device and sent up as soon as there is signal
Get that invoice to the customer	Sends on sync	Goes out after the invoice reaches the office, and still follows your approval setting
Chat with the office	Needs signal	Neither reading nor sending works without a connection — messages are not held for later
Show the customer a live tracking map	Needs signal	A live position needs a live connection
Add a customer or job that isn't already on the device	Needs signal	Sync before you leave, or wait for signal

Completing a job works offline too, with the same requirements it has anywhere: a before photo, a signature and an after photo. The whole package — photos, signature, notes, invoice — is held on the handset and goes up in order once the phone reconnects.

The longer version, including how a deliberate sync differs from a browser that merely happens to have kept a screen around, is on the mobile and offline app page. Invoice approval settings are covered on the invoicing page.

Reconnect, Sync and Troubleshoot

When the phone finds signal again, the work held on the device — status changes, checklist ticks, notes, photos, invoices, signatures, payments — goes up to the office in a sensible order without anyone pressing anything. If an item fails, Opsler retries it a few times before flagging it rather than dropping it quietly. Five things that actually go wrong, and the fix for each:

There is no install option in the menu

Check the browser first. On an iPhone or iPad it has to be Safari — Chrome and Firefox on iOS will run Opsler but hand the install step back to Safari. On a computer, make sure the browser is up to date and that you are signed in to Opsler rather than sitting on the sign-in screen.

The technician opens the app and the job list is empty

Almost always the Offline Sync was never run, or was run before today's jobs were assigned. Get back into signal, open More, tap Offline Sync, tap Refresh Sync, and check the Cached Data counts before driving off.

Sync for Offline won't run

The button is disabled with no connection — you cannot prepare for offline work while already offline. Reconnect to wifi or mobile data properly, not to one bar that looks like a connection, and try again.

Work done offline hasn't appeared in the office

Same root cause most of the time: the device needs a real connection. Reconnect, open the app and run the sync, and leave the app open until the counts settle. If a brand-new estimate is the thing missing, that one is expected — reopen the draft with a connection and send it from there.

A dispatcher and a technician edited the same job

Held actions replay when the device reconnects and the technician's field record is applied as it arrives. If your office regularly edits jobs technicians already have open, test that against your own workflow during the trial — airplane mode, edit from both ends, confirm the result — rather than discovering it on a live job.

Installation FAQs

No. There is no Opsler listing in the App Store or on Google Play, and you don't need one. You open Opsler in your browser and install it from there. It then sits on your home screen or dock with its own icon and opens in its own window, without the browser tabs and address bar.

Windows and Mac computers, Android phones and tablets, and iPhones and iPads. The browser matters more than the device: Chrome and Edge handle it on a computer, Chrome on Android, and Safari on iPhone and iPad. Opsler runs in any current browser — the table above is only about which ones also offer the install step.

It's the same Opsler. Installing changes how you reach it and how it looks — its own icon, its own window, no browser furniture — and it is what lets the Field Agent App hold a technician's work when the signal drops. One thing to know on a Mac: a Safari web app keeps its own sign-in separate from the browser, so you may be asked to sign in once more the first time you open it.

No. Installing is free on every plan and there is nothing to unlock. The free Budding plan covers 2 seats — 1 admin and 1 technician — and 50 jobs a month. Pro is $25 per seat per month with no seat minimum and a 14-day trial that doesn't ask for a card. Two things worth knowing before you test in the field: GPS snapshots and per-job work timers are switched off on Budding.

Not on its own. Installing gets Opsler onto the device. Working with no signal needs one more step: open More in the Field Agent App, tap Offline Sync and run it before heading out, which downloads today's jobs, the parts and service catalogs, tax settings, the assigned van and its stock levels, and customer history to the phone. A technician who installs the app but never syncs will find an empty screen in a basement.

There aren't any to install. There is no app-store review queue, no separate iPhone and Android versions drifting apart, and no technician running something six versions old because they never tapped update. Everyone is on the current version because there is only one.
