Prepare while connected
Open and prepare the inspection before leaving reliable connectivity.
OFFLINE FIRE DOOR INSPECTIONS
Keep inspecting when the signal disappears
Prepare a Fire Door inspection while connected, continue recording answers and evidence in low-signal areas, then synchronise safely when connectivity returns. MYLU Fire keeps the field workflow moving without pretending every building has reliable mobile coverage.

PREPARE BEFORE SIGNAL LOSS
Take the inspection with you before you go offline
Offline working starts deliberately. While connected, prepare the inspection so the Fire Door records and inspection state needed for the visit are available locally on the device before you enter a basement, riser, plant area or other low-signal location.
Continue on site
Work through the structured Fire Door inspection without relying on a live mobile connection.
Keep evidence locally
Inspection answers and captured evidence remain available on the device while offline.
Synchronise later
When connectivity returns, use the normal sync and retry workflow to move the prepared work back to the server safely.
FIELD WORK WITHOUT A LIVE CONNECTION
Record the inspection where the door actually is
MYLU Fire is designed for the reality of inspection work inside buildings. Once prepared, the inspector can continue recording inspection answers and evidence locally instead of abandoning the workflow when the mobile signal drops.
The offline state is deliberate and visible, so the inspector can understand whether the inspection is prepared, waiting to sync or requires another retry.
Structured inspection
Continue the same door-by-door workflow used online.
Local evidence
Keep captured evidence with the prepared inspection until it can upload safely.
Visible status
See whether work is prepared, pending synchronisation or needs another retry.
No duplicate restart
Return to the prepared inspection rather than rebuilding the visit from handwritten notes.
RECONNECT & SYNCHRONISE
Bring the inspection back online without losing the audit trail
When connectivity returns, MYLU Fire synchronises the prepared inspection through a controlled retry process. Evidence uploads use the same provenance and immutable-original model as online work, and sync conflicts are surfaced rather than silently overwriting server state.
- Controlled reconnect and retry
- Evidence remains tied to the correct inspection
- Conflict detection prevents silent overwrites
- Completed work returns to the normal review workflow
IPHONE & PWA GUIDANCE
Offline working is reliable when the inspection is prepared properly
MYLU Fire is an installable Progressive Web App. On iPhone, keep the installed PWA open or backgrounded normally while working offline. Avoid force-closing it while offline because iOS may require connectivity before a fully closed installed PWA can launch again.
This is a platform limitation rather than a loss of the locally retained inspection data. Prepared inspection and evidence state remains on the device until synchronisation can complete.
EVIDENCE CONTINUITY
Keep photographs and inspection evidence with the offline visit
Evidence captured during prepared offline work remains connected to the relevant Fire Door and inspection. When connectivity returns, the normal upload workflow preserves source provenance and the immutable original rather than turning offline evidence into an untracked attachment.
This keeps offline field work within the same evidence model used for connected inspections.
Correct door context
Evidence remains associated with the Fire Door being inspected.
Source provenance
Camera and existing-photo sources remain distinguishable where applicable.
Immutable original
The original evidence file is retained when upload completes.
Review-ready
Synchronised inspections can move into the normal submit, review and approval lifecycle.
BUILT FOR REAL BUILDINGS
Useful wherever connectivity is unreliable
Offline capability is most valuable where inspection work and mobile coverage do not line up. MYLU Fire helps inspectors keep the workflow consistent in the parts of buildings where a browser-only online process would otherwise become a liability.
Basements & plant areas
Prepare before entering lower levels or enclosed spaces where mobile reception is weak.
Stair cores & risers
Continue inspection work without relying on each landing having a usable connection.
Large portfolios
Keep a repeatable offline process for inspectors moving across varied building environments.
OFFLINE INSPECTION FAQ
Questions about offline Fire Door inspections
Can MYLU Fire be used without mobile signal?
Yes, after the inspection has been prepared while connected. Inspectors can continue recording answers and evidence locally, then synchronise when connectivity returns.
Do I need to prepare an inspection before going offline?
Yes. MYLU Fire uses a deliberate preparation step so the inspection state needed for the visit is available locally before the inspector enters a low-signal area.
What happens to photographs captured while offline?
Evidence captured during prepared offline work remains associated with the relevant inspection and Fire Door. When connectivity returns, the normal upload and retry workflow preserves source provenance and the immutable original.
Will MYLU Fire automatically synchronise when signal returns?
The offline workflow provides controlled synchronisation and retry when connectivity returns, with visible state so inspectors can confirm whether work has completed or still needs attention.
Can I force-close MYLU Fire while offline on an iPhone?
It is best not to. iOS may require connectivity before a fully closed installed Progressive Web App can launch again. Keep MYLU Fire open or backgrounded normally while working offline.
Does going offline remove the Fire Door history or evidence trail?
No. Prepared offline work remains part of the same Fire Door, inspection and evidence model. After synchronisation, it continues through the normal review, approval and reporting workflow.
Is MYLU Fire a native offline app from the App Store?
No. MYLU Fire is an installable Progressive Web App used through a modern browser. It supports prepared offline inspection work but is not distributed as a native App Store or Google Play application.
