FEATURE / 05 · OFFLINE CANVASSING

Offline canvassing app, knock doors anywhere, sync when you're ready.

A canvassing web app built for dead zones, apartment basements, and rural routes. It saves the walk list (the addresses each canvasser will visit) on the phone, and it stores every disposition (door result), note, and survey response in the browser's storage (IndexedDB). When signal returns, the saved records upload in the background.

Capabilities

How offline canvassing works without cell signal

Most canvassing tools assume the phone has a connection. Beacon was designed to work without one. Every screen the canvasser uses works without cell service, and the data uploads when a connection returns.

/01, CACHE

Offline canvassing storage on the phone

The app, walk list, contact details, and survey questions are all saved to the phone the first time it connects, so the canvasser can open the app at the door without waiting on a network.

App saved on the phone
Walk list + contacts saved
Survey forms load from the phone

/02, QUEUE

Offline queue for recording dispositions

Every disposition, note, and survey response is saved to the phone first. The saved records stay through browser closes and phone restarts, so nothing is lost if the battery dies.

Queue stored in IndexedDB
Kept through restarts
Visible "pending sync" count

/03, UPLOAD

Background upload on reconnect

When the phone finds a connection, the saved records upload together in the background. If two canvassers visit the same contact, Beacon keeps both visits as separate records.

Background batch upload
Duplicate visits kept as separate records
Online indicator on every screen

At the door, without signal

The offline canvassing door screen works without cell signal

Disposition buttons, survey forms, and AI talking points saved during the last connection load directly from the phone. The "Online" label at the top of the walk list turns red when the signal drops, but the rest of the app keeps working as before.

How an offline shift runs

How an offline canvassing shift runs, end to end

/01

Connect before you go

Open the app on wifi and tap sync. The walk list, contact details, survey questions, and territory boundaries are saved to the phone.

/02

Knock without signal

Walk the list, record dispositions, complete surveys, and leave notes. Every action is saved directly on the phone. The "Online" label turns red, but nothing else changes.

/03

Return and upload automatically

When the phone has signal again, the saved records upload in the background and the pending count returns to zero.

/04

Manager sees the data

Knocks appear in the activity feed and the map updates as the records arrive, so there is no spreadsheet to hand off and nothing to reconcile at the end of the day.

FAQ

Offline canvassing app questions, answered

Q / 01

How do records upload after canvassing offline?

Every offline interaction is saved in the phone's browser storage (IndexedDB). When the phone has a connection again, the saved interactions upload to Beacon together. If two canvassers visited the same contact, Beacon keeps both visits as separate records.

Q / 02

What if my phone dies before the data uploads?

The data stays saved on the phone through browser closes, app restarts, and phone reboots. Open the app again once you have a connection, and the saved records upload normally.

Q / 03

Do I need to install the offline canvassing app from the App Store?

No. Beacon is a Progressive Web App, a website that installs like an app. On Android, Chrome offers "Add to Home Screen," and on iOS you tap the Safari share button and choose "Add to Home Screen." You get the app icon and a full-screen view without an app store account.

Q / 04

How much data does the offline canvassing app use?

The app is under 2MB on first load, and a typical 500-contact walk list is under 1MB. Once saved, the app uses no data until it uploads, and a busy day of door knocks (100+ records) usually uploads in well under 500KB.
