# Work offline

> The mobile app is offline-first: it keeps working without a connection, shows a banner while you're offline, and syncs your changes when you reconnect.

Budget Bandit on mobile is offline-first. Your budget lives on the device, so the app stays fully usable on a plane, in a basement, or anywhere the signal drops. Edits you make offline save locally and sync the moment you're back online.

## What works offline

Effectively everything you do day to day:

* Open the Budget, Transactions, Accounts, and Reports tabs.
* Add and edit transactions with [quick-add](/mobile/add-on-the-go).
* Assign money and move it between categories.
* Check balances and what's safe to pay on your cards.

Because the data is already on your phone, these screens load and respond without waiting on the network.

## The offline banner

When the app loses its connection, a thin banner appears at the top:

> Offline — changes save on this device and sync when you reconnect

It's a reassurance, not a warning. Keep working; nothing is lost. The banner clears on its own once you're back online.

## Syncing when you reconnect

When the connection returns, the app uploads the changes you made offline and pulls down anything that changed elsewhere — including edits made on the web or by someone you [share with](/sharing/invite-a-partner). You don't trigger this; it happens automatically.

<Note>
  Settings shows your current status as **Connected** or **Offline**, so you can confirm at a glance whether your latest changes have synced.
</Note>

## Things that need a connection

A few actions reach a server by nature and won't complete offline — for example, [linking a bank](/accounts/connect-a-bank) and pulling fresh bank transactions. Queue your manual edits offline; run bank-linked actions once you're back online.

## If a change doesn't appear on another device

* Confirm both devices are online and show **Connected**.
* Give sync a moment to finish after reconnecting.
* Still missing? See [Fix sync problems](/accounts/fix-sync-problems).
