# Apps — Group CERs by Application

URL: https://docs.nexart.io/docs/dashboard/apps

Apps organise Certified Execution Records inside a project, letting teams separate services and components while keeping records filterable in the NexArt.

## Overview

Apps are organizational units within a Project. They represent the specific application, service, or workflow that produced an attestation.

- Project- Apps- CER records

Apps are used for organization and filtering. They do not change the cryptographic structure of CERs.

## Why Use Apps

- Organization. Separate CER records by application or microservice.
- Filtering. Filter the dashboard view to show attestations for a specific app.
- Audit Context. App identifiers are included in CER metadata and audit exports, helping auditors understand which system produced the execution.
- Operational Visibility. Track which services generate attestations and monitor activity per app.

## Creating an App

- Open the NexArt Dashboard
- Navigate to Projects
- Select the project where the app should belong
- Open the Apps tab
- Click Add App
- Enter an app name

Examples of app names:

- customer-chatbot
- document-summarizer
- fraud-detector
- support-assistant

## Using Apps in Attestations

When creating a CER, the app identifier may be included in the snapshot metadata:

App identifier in CER metadata

```
{
  "snapshot": {
    "metadata": {
      "appId": "customer-chatbot",
      "projectId": "proj_abc123"
    }
  }
}
```

This allows NexArt to associate the record with the correct application in the dashboard. The association is used for dashboard organization and exports.

## Apps in the Dashboard

In the dashboard, apps let you:

- Filter CER records by app
- View attestations generated by a specific service
- Export records scoped to an app
