Offline Mode
The LiteLog app also works without an internet connection — in underground garages, basements, halls, or on remote sites your employees simply keep working. All captured data is stored locally on the device and synchronized automatically as soon as a connection is available again.
What is offline mode for?
Offline mode ensures that evidence is captured without gaps even where there is no reception — capture continues unchanged, and the app catches up on the transfer later. This page describes what works offline, how synchronization works and where the limits are.
What works offline
| Feature | Offline |
|---|---|
| Running patrols — scanning checkpoints via QR code or NFC, beacon points are captured automatically on approach | ✅ |
| Capturing incident reports — including photos | ✅ |
| Time tracking — start, pause, and stop working time; shift sign-in/sign-out | ✅ |
| Filling in forms — e.g. shift reports and checklists | ✅ |
| Status reports — including check-ins via the status reporter | ✅ |
| Creating and completing tasks — new tasks are saved on the device first and uploaded later | ✅ |
| Viewing documents — PDFs already downloaded | ✅ |
To make this possible, the app keeps the required data locally: properties and checkpoints, patrol tasks, and documents are loaded onto the device while working with a connection.
The buffer zone (geofencing) and beacon checks also apply offline: both are evaluated locally on the device — no server connection is needed for them. The timestamp is always the moment of capture — not the time of the later synchronization.
Automatic synchronization
As soon as the device is back online, the app automatically transfers all not-yet-synchronized records to the server — tag scans, time tracking entries, attendance, incident reports including images, form responses, status reports, task completions, and tasks created in the app. Nothing needs to be triggered manually.
- Failed transfers are stored and retried automatically. If the server permanently rejects a newly created task, the app shows Upload failed; you can then discard the task in the detail view.
- Depending on the amount of data (e.g. many photos), the transfer can take a while after a long offline period — keep the app open for it.
Limits of offline mode
- Signing in requires internet — Login (and thus the first start after installation) needs a connection. Once signed in, the app remains usable offline. If the server cannot be reached, the app reports "No connection to the server. Please check your internet connection and try again."
- Data must have been loaded once — Properties, checkpoints, patrols, and documents are only available offline if they were previously loaded with a connection. Ideally open the app once with internet before heading into a dead zone.
- Patrols that were not loaded — If a planned patrol cannot be loaded (e.g. because it is not available offline or was deleted in the meantime), the app deliberately aborts the start and shows a notice — so no scans get assigned to the wrong patrol. Details: Running a patrol.
- Rotating kiosk QR — Checking in via the kiosk screen requires a connection, because the rotating code is generated and validated server-side. Static QR codes and NFC tags, on the other hand, work offline.
- Form drafts with media — Drafts containing photos or a signature are best continued on the same device; across devices the answers are carried over, but media attachments are not.
- Tasks without a due date — Offline, the app only keeps open tasks with a due date within the synchronization period. Tasks without a due date do not appear offline, not even when scanning a linked checkpoint.
- Live features — Chat, live views, and loading new tasks or changes from the portal naturally require a connection. Editing and changing the status of a task created in the app is also only possible after it has been uploaded; completing works before that.
- Digital signature with password — If your company demands a digital signature when submitting incident reports and forms or when completing tasks, the password method only works with a connection. NFC chip and QR code also sign offline; your data is never lost even without a signature — a missing mandatory signature is recorded as a deviation.
- Signature PIN offline: 7 days after an online use — The signature PIN works without a connection once it has been used or set up online on this device: every online PIN signature in the app renews a grant valid for 7 days. Therefore set up the PIN with an internet connection — the dashboard reminds you with the Set up signature PIN card as long as no PIN is set; a PIN cannot be created without a connection. After a PIN change, a reset by the administration or a sign-out, an online signature is required first. A PIN set up in the portal does not receive this grant automatically — use it once in the app with a connection. Offline as well: five failed attempts lock the PIN for 15 minutes.
If synchronization gets stuck
If entries remain marked as "not synchronized" permanently, the guided recovery in the app's help area can assist: it first uploads all pending data and then resets the app cleanly — without data loss. See Help — Recovery.
Good to know
:::tip Note
- Offline mode works silently in the background — your employees do not need to switch anything.
- Timestamps are set at capture time, not at synchronization time: a checkpoint scanned offline carries the actual scan time.
- The electronic guard book benefits as well: evidence is captured without gaps even when the site has no reception. :::
