# Use app metadata in apps

*This article describes the steps for showing app data using App Info in the Tulip App Editor.*

## Overview

There are several options for referencing app data using 'App Info' in Tulip.

You can access all of these options in the App Editor in two ways.

## Using Variables

You can create a Variable in an app to access app data by creating a variable with the datasource set to App Info. See below the options available within this area of the App Editor.

### Selecting the Variable

- Create a new Variable
- Set the Datasource as 'App Info' and select the App Info data to display.

## Expression Editor

- You can access app data using the Expression Editor, which can be used in Triggers.
- You will need to create a trigger Action set as:
  - Data Manipulation → Store → Expression

Note that you will need to enter your variables as @App Info.<data data-tomark-pass=""> in order to access data from the Expression Editor.</data>

**App Info**

**App Info**is a subset of the data available within an application automatically. This data can be used both in **Widgets**and**Triggers.**This includes the current date and time, the app name, the app version, the current shift, and more.

**Variables**

**Variables**are a location to store app information. Variables have a specific type that must match the contents they can store.

Variables are only accessible within a single application and are cleared when the app is restarted or completed.

**Expression**

A configured code snippet that returns a calculated value based on certain inputs. **Expressions**have access to all of the variables, Table Records, and any other data available to an application.

**Trigger**

**Triggers** are groups of logic that are tied to an app event, such as step open, timer, widget interaction, etc. App builders can add triggers to **widgets**, **machines**, **devices**, **apps**, and **steps**.

**Triggers** can contain **actions**, **transitions**, and **conditions**.

**Action**

**Actions**are different operations that can be executed in **Triggers. Actions**cannot move users to other apps, or other**steps.**

Many **Actions**can be added to a single **Trigger.**

*ex. Store the value of variable x to table field y, Print app step, Adjust Edge device GPIO pin.*

**Station**

**Stations**are a digital representation of a physical place or device in your facility. Stations are 1:1 with **Interfaces (display devices)** running Tulip Player, but Stations can also be assigned **Edge Devices,**Tulip Vision Camera Configurations, Machines,****and more.

**Step**

A view your users will see within an application. **Steps** can be viewed chronologically or in whatever order best fits your process.

Steps can be grouped into **Step Groups**to manage and organize your app Steps.

**Step Group**

**Step Groups**are a mechanism to organize and group individual steps. Step groups can be duplicated/deleted and reordered like individual steps.
