# Creating Apps

Requirements:

* [You have a canvas with Output Format](/en/craft/output-format)
* [Your canvas is published](/en/craft/publishing)

## What are apps?

Apps are one of **Tela**'s main features. They are useful when you already have a reliable Canvas and need to give different users
a way to create multiple *runs* of your Canvas at the same time, providing files to populate a [Variable](/en/craft/using-variables)
and downloading the result of all the runs in a spreadsheet.

<Tip>
  Our **apps** are related to a Canvas, but you can share the app link with any person with access to your workspace
  and they will be able to use the app without needing to interact with the Canvas.
</Tip>

## Creating an App

After publishing a version of your Canvas, you can click the `Deploy` button in the top right corner of your canvas page:

<Frame>
  <img class="rounded-2xl" src="https://mintcdn.com/meistrari/pblu7JGV78zF0-_0/images/guides/craft/creating-apps/deploy.png?fit=max&auto=format&n=pblu7JGV78zF0-_0&q=85&s=62689850b2ed42066c3da2ca4631ee5f" alt="Deploy button" width="378" height="44" data-path="images/guides/craft/creating-apps/deploy.png" />
</Frame>

When starting the *Deploy* process, you will be prompted to select one of the 2 available templates.

Tela currently supports 2 app Templates, the simpler **[Data Extraction Tool](/en/workstation/data-extraction-tool)** and the more robust **[Workstation](/en/workstation/workstation)**. We will explain each one in details in a while.

Regardless of the selected template, clicking `Continue` will take you to the app configuration dialog, where you can add a name and a simple description of your app.

You can also select the *Document Variable* which will be populated with the input files when running your new app.

<Note>We currently support only one variable per app, but we are working on experiences with multiple variables</Note>

After configuring your app, you can copy and share your app link or click `Open Web App` to see your app in action!

Now that you have configured and opened your app's page, we can dive deeper into each one of the templates.

* [Workstation](/en/workstation/workstation)

## Updating your App

If your app is not getting the results you expect, maybe you need to [edit your prompt](/en/craft/editing-prompts) or change something in your **Canvas**.

<Tip>You can go directly to the Canvas associated with your app by clicking the `…` button in the top left corner of your App's page.</Tip>

Your app is associated with the **Published** version of your Canvas, so please remember to [publish your canvas](/en/craft/publishing) to see the changes in your app.
