At a glance

Use this guide when

Setting up the mobile web app on technician phones and working in basements or remote areas with no cell signal.

Best practice

Add the app to the mobile home screen via Safari or Chrome for seamless full-screen operation.

Watch for

Offline queue entries must be synced within 12 hours of creation; older entries are permanently rejected.

01

Install the Field App to your mobile home screen

  1. iOS (Safari): Open your field access link, tap the Share icon at the bottom of Safari, and select "Add to Home Screen".
  2. Android (Chrome): Open your field access link, tap the 3-dot menu in Chrome, and select "Install app" or "Add to Home screen".
  3. Launch the app from your home screen icon for full-screen mobile operation.
02

Work in basements and dead zones with offline queueing

  • When signal drops, the field app displays an offline status indicator.
  • Technicians can continue clocking shifts, checking off punch list items, taking photos, and typing job notes.
  • All updates are securely stored in the mobile browser’s encrypted offline storage queue.
03

The 12-hour sync window invariant

CRITICAL OFFLINE RULE: As soon as mobile signal or Wi-Fi is restored, open the app or visit /field/offline to sync queued updates. Any offline queue items older than 12 hours will be permanently rejected by the server to avoid overwriting newer changes.

Completion check

Confirm before moving on

Use these checks to make sure the dashboard and the real-world workflow agree.

  • Field app is installed on mobile home screen as a Progressive Web App.
  • Offline indicator displays correctly when mobile data is disconnected.
  • Offline job notes and time punches sync immediately upon reconnecting to signal.

Troubleshooting

When the workflow doesn’t look right

Offline queue shows pending items after returning to service.

Open the field app, tap the offline indicator, and click "Sync Now".

App asks for login again when reopening.

Ensure you launch the app from the installed Home Screen icon rather than opening private/incognito browser tabs.
