Offline Data Screen

​
Overview

The Fentu Mobile Technician app is built for field work — including situations where internet connectivity is limited or unavailable. The Offline Data feature ensures that you can continue working without interruption, and that all your work is safely stored on your device until it can be synced to the Fentu server.
Offline mode is automatic. The app detects when you lose connectivity and switches to offline mode seamlessly. There is no need to manually enable it.

​
How Offline Mode Works

When the app loses internet connectivity:
  1. The app displays a small Offline indicator in the top status bar.
  2. You continue working normally — completing tasks, filling in checklists, logging time, and adding notes.
  3. All changes are saved locally on your device in a secure offline queue.
  4. When connectivity is restored, the app automatically syncs all pending changes to the Fentu server.

​
What Works Offline

The following actions can be performed without an internet connection:
  • View task details and task line items
  • Complete checklists (yes/no, pass/fail answers)
  • Fill in readout values
  • Progress through wizard steps
  • Update task status (e.g. In Progress, Paused)
  • Add notes to tasks
  • Start, stop, and switch timers
  • Add manual time entries
  • View your time log for the day
  • View asset details for assets previously downloaded to the device
  • Add condition notes
  • Log readouts
  • View service history (for cached assets)
  • Take photos and attach them to tasks or assets
  • View previously downloaded file attachments

​
What Requires Connectivity

Some actions require an active connection and will be queued or unavailable in offline mode:

​
Offline Actions Queue

Offline Actions Queue The Actions tab in the Offline Data screen shows every change you have made while offline that is waiting to be synced. This gives you full visibility into what is pending.

​
Reading the Queue

Each item in the Actions queue displays:

​
Failed Actions

If a sync attempt fails (for example, due to a conflict with a change made in the back office), the action is marked as Failed with a red indicator. Tap the failed item to see the error details and choose how to resolve it:
  • Retry — Attempt to sync the action again
  • Discard — Remove the action from the queue (your local change will be lost)
  • View Conflict — If there is a data conflict, compare your version with the server version and choose which one to keep
Discarding a failed action permanently removes that local change. It cannot be recovered. Only discard if you are certain the change is no longer needed.

​
Sync Data

Sync Data Screen The Sync Data tab shows the current synchronisation status between your device and the Fentu server.

​
Sync Status Indicators

​
Manual Sync

The app syncs automatically whenever connectivity is available, but you can also trigger a manual sync:
  1. Go to Offline Data → Sync Data tab.
  2. Tap Sync Now.
  3. The app will immediately attempt to upload all pending changes and download any updates from the server.
Trigger a manual sync at the start of the day (when you have a good Wi-Fi connection) to ensure all your tasks, assets, and attachments are downloaded and available for offline use throughout the day.

​
Pre-Downloading Data for Offline Use

To ensure you have all the data you need before going into the field:
  1. Go to Offline Data → Sync Data tab.
  2. Tap Download for Offline.
  3. The app will download your assigned tasks for the next 7 days (or as configured by your administrator), along with all linked assets, attachments, and manuals.
Pre-downloading large files (such as PDF manuals) requires a Wi-Fi connection. The app will warn you if you attempt to download over a mobile data connection.

​
Storage Usage

At the bottom of the Sync Data screen, a storage indicator shows how much of your device storage the app is using for offline data. If storage is running low:
  1. Tap Manage Offline Data.
  2. Review and remove downloaded files for tasks and assets that have already been completed.
  3. Tap Clear Completed Task Data to free up space automatically.
