Arcus Command is the Android app your warehouse team uses on handheld scanners to pick, pack, capture serial numbers and fulfill packages. It is installed from your company’s download page, not from an app store, and it tells you when a newer version is ready.

​
Before You Start

  • An Android device running Android 8.0 or newer, with a web browser.
  • Your entity code. An admin finds it in Arcus under Settings > Scanners.
  • A user with a PIN for the scanner app.

​
Install Arcus Command

  1. On the device, open the download page and tap the Arcus Command download. The file is named Arcus-Command.apk. The browser may warn that the file might be harmful, as it does for any app downloaded outside an app store: tap Download anyway.
  2. When the download finishes, tap Open (or open the file from the browser’s Downloads list).
  3. The first time, Android asks whether to allow installs from the browser. Tap Settings, turn on Allow from this source, go back, and open the file again.
  4. Tap Install. Google Play Protect may say App scan recommended because it has not seen this app before: tap Scan app to have it checked first, or tap More details, then Install without scanning. Either way the app installs.
  5. Tap Open, then enter your entity code and tap Connect, or tap Scan Setup QR and scan the code an admin shows you.
  6. Pick your name and enter your PIN.
The permission in step 3 is asked once per device. You can turn it off again afterwards under Settings > Apps > Special app access > Install unknown apps; turn it back on before the next update.

​
Update Arcus Command

Arcus Command checks for a newer version when it opens and every few hours while it stays open.
  1. When a newer version is ready, the Dashboard shows Update available with the new version number.
  2. Tap Download. The browser downloads the new version (tap Download anyway if it warns about the file).
  3. Tap Open on the finished download, then Update, and answer Play Protect as in step 4 of Install Arcus Command. Android says App updated.
  4. Tap Open and enter your PIN. The app keeps your entity, your user and your settings.
You can also check on demand: open Settings (tap your initials on the Dashboard), then tap App updates under About. The row says whether you are up to date, when it last checked, or which version is available.
Tapping the close button on the banner hides it until the app restarts. The update stays available under Settings > About > App updates.

​
When an update is required

If your version is too old to keep working with Arcus, the app shows Update required instead of the Dashboard. Tap Download update and install it as above. Tap Check again if you have just installed the new version and the screen is still showing.

​
Replace an Older Copy That Will Not Update

Copies of Arcus Command installed before October 31, 2026 were packaged differently, so the new version cannot install over them. Android says App not installed or reports that the package conflicts with an existing one. Replace the old copy once:
  1. Press and hold the Arcus Command icon, tap App info, then Uninstall.
  2. Install from the download page, as in Install Arcus Command.
  3. Enter your entity code again and sign in with your PIN.
After this one replacement, every later update installs over the app from the banner.

​
Which Version Am I On?

Open Settings and look under About. The first row shows the version, the build number and which build you have installed. The build number is what decides whether an update is newer.
