# Apps

> Create an App from a notebook to automate scheduled workflow runs and track run history.

# Using an App

## Description

Apps allow you to automate the execution of workflows on a scheduled basis. If your input data changes regularly but your workflow remains consistent, an App enables you to automate re-runs while capturing results over time in a structured run history.

***

## Application

Use an App when:

* You want to **repeatedly run the same notebook** with new or updated data.
* You need a **versioned history of results** across multiple data states.
* You want to **eliminate manual runs** by scheduling workflow execution.

Each run creates a snapshot of the results, allowing you to track changes, monitor consistency, and perform time-based analysis.

***

## How to Use and Configure an App

### 1. Prepare a Notebook

Build a notebook containing your desired workflow using supported **manipulators**:

* **Import**
* **Transform**
* **Apply**

> ⚠️ **Note:**
>
> * **Do not use Model** manipulators (model training) in Apps. Apps that contain a Model step will fail to run.
> * **Explore** manipulators are partially supported—these won't appear in run history but won't break your App.

***

### 2. Create an App from a Notebook

1. Open the notebook in the editor.

2. Click **"Create App"** in the top-right corner, or press **Ctrl + P**.

3. A modal will open, allowing you to **select which manipulators to show or hide** in run history.

   * This only controls visibility, not execution.
   * Currently you cannot change these settings later via the app configuration.

4. **Enter a name** for your app.

5. Click **"Create."**

After creation:

* You'll see a confirmation message and a summary view of the manipulators you selected.

* Choose whether to **go to the App** page or return to the notebook.

***

### 3. Set Up Automation

There are two ways to access your App

* From the **confirmation screen**, click **"Go to Application"**.
* Or, navigate to **"My Content"** and open the App (it will be in the same folder as its source notebook).

To configure automation:

1. Click **"Setup Automation"** in the top-right corner of the App view.

2. In the automation modal, configure the following:

#### Automation Settings

* **Run Frequency**:
  * **Minimum frequency:** Every **30 minutes**\
    This is the shortest interval currently supported by the platform.
  * *Need more frequent runs? Contact the support team to explore custom configurations.*
  * **Recommended maximum:** Between **12 to 48 hours**\
    This range balances automation usefulness with system efficiency and reliability.
  * **Technical maximum:** There is **no enforced upper limit** — you can schedule runs at intervals of **hundreds of hours**, though this is rarely necessary in practice.
* **Start and End Times**:
  * Define when the automation should **start** (today or a future date).
  * Optionally set an **end time** (must be after the start time).
* Select the Enable Automation toggle

3. Click **"Save changes"** to apply the schedule.

***

### 4. Monitor Run History

* Your App will run based on the schedule.
* Visit the **Run History** tab after the first scheduled time (e.g., 3:00 PM today).
* A **spinner icon** will appear for runs in progress on the right-hand side of the run list.
* You'll be able to track results and compare past runs at any time.

## Supported Manipulator Types in Apps

*Use this guide to determine whether your notebook is compatible with App creation.*\
Only certain manipulator types are supported in Apps. Notebooks that include unsupported types (like Model) will fail when run as an App.

| Manipulator   | Supported in Apps | Notes                                                                                                                                                                                         |
| ------------- | ----------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Import**    | ✅ Yes             | Fully supported                                                                                                                                                                               |
| **Explore**   | ⚠️ Partial        | Will not appear in run history, but won't break the App                                                                                                                                       |
| **Transform** | ✅ Yes             | Fully supported                                                                                                                                                                               |
| **Model**     | ❌ Not Supported   | Model training cannot run inside an App. Train your model in a separate notebook, then create an App from a notebook that uses Apply manipulators to make predictions with the trained model. |
| **Apply**     | ✅ Yes             | Fully supported                                                                                                                                                                               |

## Editing an App

### How to Access and Edit an App

You can modify the **automation settings** of an App, but not the manipulators displayed in the run history.

1. Go to **"My Content"** and locate the App (in the same folder as the original notebook).

   > 📝 *Note: Apps cannot currently be moved, renamed, or deleted.*

2. Open the App.

3. Click **"Change"** in the top-right corner of the App view.

4. A modal will appear showing the current App settings:

   * **Edit run frequency, start time, or end time** as needed.

5. Click **"Save Changes"** to apply updates, or **"Cancel"** to discard them.

> ⚠️ **Note**: You cannot modify which manipulators are shown or hidden in the run history after creation. This setting is fixed during the initial setup.
