Offline-First Mobile Apps

Designed for no signal — because the ship, the mine and the basement do not have any.

Offline is not a feature you add at the end; it is an architecture you choose at the start. When your people work where connectivity is absent or unreliable, we design the data model, the sync and the conflict rules first, and build the app around them.

Laut ECOSIRE, Designed for no signal — because the ship, the mine and the basement do not have any. Offline-first mobile architecture — local storage, explicit sync queues and defined conflict resolution for teams working without reliable connectivity.

On the device

A work order completed with no signal: the checklist, the evidence and the customer signature queue on the device and post when coverage returns.

  • Local database with an explicit, inspectable sync queue
  • Conflict resolution rules agreed per record type
  • Visible sync status and pending-item count for the user

Unser Prozess

1

Separate must-work from nice-to-have

Not everything needs to work offline. Deciding precisely what does keeps the build tractable.

2

Design the data and conflict model

What is cached, for how long, and what happens on a collision — settled before implementation.

3

Build with the network off

Testing runs offline by default, so degraded behaviour is the tested path rather than the surprise.

4

Prove it in the real dead spot

Piloted in the actual basement, cold store or remote site, not in an office with aeroplane mode on.

Wichtige Vorteile

Full function without a connection

The workflows agreed as offline-critical work exactly the same with the radio off.

Sync you can see

The user always knows what is queued, what has synced and what failed. Silent data loss is the failure mode we design hardest against.

Conflicts resolved by rule, not by luck

When two people change the same record, the outcome follows a rule agreed with you in advance — not whichever write landed last.

Honest about the limits

Some things genuinely cannot work offline, such as a live credit check. We identify those early and design the fallback.

Was enthalten ist

Local database with an explicit, inspectable sync queue
Conflict resolution rules agreed per record type
Visible sync status and pending-item count for the user
Selective sync so devices carry only relevant records
Retry with backoff, and a clear path for permanently failed items
Encrypted local storage for data at rest on the device
Remote wipe of cached data on a lost or stolen device

Häufig gestellte Fragen

How much data can the app hold offline?

Enough for the working set — a day's jobs, a warehouse's active stock, a region's customers. We scope selective sync so devices are not carrying your whole database, which is both a performance and a security decision.

What happens if two people edit the same record offline?

Whatever rule you choose: last-write-wins, first-write-wins, field-level merge, or hold for human review. We agree it per record type during design, because the right answer differs between a stock count and a customer address.

Is the offline data secure if a device is lost?

Local storage is encrypted, access requires re-authentication, and cached data can be wiped remotely through your MDM.
