# Cedar Mobile

> Get around the ARMS mobile app: tabs, screen order, and switching carriers.

<Info>
  Cedar Mobile is the field app for ARMS. Use it to work inventory, receive interchanges, and run trains from a phone or tablet.
</Info>

## Sign in

Open ARMS Mobile and sign in with your Cedar account. If your company uses SSO, follow the [mobile SSO guide](/user-docs/sso/mobile).

## The tabs

When you open the app, five tabs sit along the bottom of the screen. The selected tab is highlighted in yellow.

| Tab | What it's for |
| - | - |
| **Inventory** | View and move cars in your yards |
| **Shipments** | Manage shipments (when enabled for your carrier) |
| **Trains** | Manage trains and jobs |
| **Warehouse** | Warehouse operations (when enabled for your carrier) |
| **More** | Everything else, including Interchanges, Profile, and screen order |

<Frame caption="The Inventory tab is selected. Each row is a station. Tap the star to favorite a station — favorites move to the top of the list.">

</Frame>

<Tip>
  Scroll the station list, or use the search box at the top to find a station by name.
</Tip>

This guide covers **Inventory**, **Interchanges**, and **Trains**. Shipments and Warehouse appear when your carrier has those products turned on.

## Change the tab order

Open **More → Configure screens** and drag the screens into the order you want. Use this to keep Interchanges on the tab bar if you receive cars every day.

## Switch carriers

If you work more than one railroad, change the active carrier from Profile.

<Steps>
  <Step title="Open More, then Profile">
    Tap the **More** tab, then tap **Profile**.

    <Frame caption="The More menu. Profile is near the bottom of the list.">

    </Frame>
  </Step>

  <Step title="Choose a carrier and save">
    Tap **Choose a carrier**, pick the railroad, then tap **Save**.
