# Offline field app

> Cablefolio keeps working in a plant room, a basement, or a lift: keep a property on the phone before you go, and every change made with no signal is queued and sent, in order, when the signal returns.

- Keep a whole property on the phone, with photo thumbnails and files
- Add and edit rooms, racks, devices, runs, links, notes, checklists, and photos offline
- A queue that sends oldest first and stops at the first change that does not land
- Conflicts held for a person to settle: keep mine, or take theirs

## Built for sites with no signal

Cablefolio is phone-first and installs as a web app. Before a visit, press **Keep offline** on a property and the whole property is copied to the phone, with each photo’s thumbnail and each file. Anything opened with a signal can be read again without one.

With no signal, edit as usual: clients, properties, rooms, racks, and devices; cable runs one at a time or from a pattern; links, power feeds, notes, contacts, checklists and their steps, VLANs, presets, photos, and files. A photo taken offline shows at once from the copy waiting to upload.

## A queue you can trust

Changes wait in order and send themselves, oldest first, as soon as the browser is back online. The queue stops at the first change that does not land, so a device added to a new room never arrives before its room. A refused change shows the server’s own reason.

If someone else changed the same record meanwhile, the change is held, not applied: compare what you changed with what the server has, and choose. Nothing is decided for you.

## Honest about what needs a connection

Signing in, revealing stored credentials, share links, reports and PDFs, and server-wide search say “Could not reach the server” rather than pretend to work offline. Credentials, access codes, and API tokens are never kept on the device.

## Questions and answers

### Does Cablefolio work offline?

Yes. Keep a property on the phone before a visit and add or edit rooms, racks, devices, cable runs, links, notes, checklists, photos, and files with no signal. Changes are queued and synced in order when the connection returns.

### What happens if two people edit the same record offline?

The later change is held as a conflict instead of overwriting the other. The technician compares what they changed with what the server has, then keeps theirs or takes the server’s.

### Is Cablefolio a native app?

Cablefolio is a progressive web app: it runs in the phone’s browser, can be added to the home screen, and keeps working offline, with nothing to install from an app store.
