# The mobile app

> Budget Bandit for iOS and Android: four tabs, a settings gear, and the same budget you use on the web, kept in sync.

The Budget Bandit mobile app is built for quick moves on the go — check a balance, categorize a charge, assign a few dollars — and stays in sync with the web app. It runs on iOS and Android.

To install it, see [Install the mobile app](/getting-started/install-the-mobile-app).

## Four tabs

The app opens to a bottom tab bar with four destinations:

<CardGroup cols={2}>
  <Card title="Budget" icon="wallet">
    Your envelope budget, with Ready to Assign and the credit-card payment strip.
  </Card>

  <Card title="Transactions" icon="receipt">
    The register, with a quick-add button for new entries.
  </Card>

  <Card title="Accounts" icon="credit-card">
    Account balances; tap one to open its register.
  </Card>

  <Card title="Reports" icon="chart-simple">
    A focused set of reports, including Net Worth, Spending, and Cash Flow.
  </Card>
</CardGroup>

## Settings is a gear, not a tab

Settings lives behind a gear in each screen's header rather than taking a tab slot. Tap the gear to open Settings, where you'll find your connection status, the biometric lock toggle, and other preferences.

## What's the same as the web

The mobile app reads and writes the same budget as the web app:

* Assign money and watch Ready to Assign update.
* Add, edit, and categorize transactions.
* See credit-card balances and what's safe to pay.
* Open accounts and their registers.

Changes you make on your phone show up on the web, and the other way around, once both have synced.

## What's focused for mobile

The phone app is a tuned subset, not the full web surface. The Reports tab carries a focused set — Net Worth, Spending, and Cash Flow — rather than all eleven web reports. For the complete report library, deeper filtering, and bulk tools, use the web app. See [all reports](/reports/overview).

## Built for on-the-go

Three things make the app feel right on a phone:

* [Face ID and app lock](/mobile/face-id-and-app-lock) keep your numbers private.
* [Quick-add and haptics](/mobile/add-on-the-go) make entry fast and tactile.
* [Offline-first](/mobile/offline) keeps everything working without a signal.
