Open an app and choose the **Settings** tab.

![The Details section of an app's settings](https://docs.fortytwo.io/screenshots/ai-universe/app-settings-tab.webp)

| Section | What you set or see |
|-|-|
| **Details** | Name, description and department, and the app's **Owner** (**Assign owner**). The owner is named in cost and vulnerability reports. |
| **Model** | Which model the app uses by default. |
| **AI agent** | The agent's settings. Most of this is easier from the [Agents](https://docs.fortytwo.io/ai-universe/apps/agents/) tab. |
| **Keys & passwords** | Secrets the app needs, such as an API key for another system. They are stored in Azure Key Vault, never in the code. |
| **Size & database** | How much computing power the app gets, and its database. |
| **Rate limit** | How many AI requests the app may make, to protect your budget. |
| **Cost** | What this app has spent on AI. |
| **Logs** | The app's own logs, for troubleshooting. |
| **Compliance** | The app's entry in the [AI system register](https://docs.fortytwo.io/ai-universe/governance/compliance/). |
| **Repository name**, **Links** | Where the code lives, and links shown with the app. |
| **Infrastructure** | The Azure resources behind the app. For IT. |
| **Remove** | Take the app out of service. |

## App size

| Size | For | Roughly, per month |
|-|-|-|
| **Lite** | Small web apps, demos and internal tools. Sleeps when nobody uses it, and wakes on the next visit in a few seconds. | $0 to $20 |
| **Standard** | Apps people use every day. Always on, so every visit is instant. | $12 to $39 |
| **Production** | Apps that must stay up through real traffic. At least two copies running, more under load. | $47 to $160 |

Prices are approximate list prices for the app's container alone. A database is priced separately. Changing size is applied through a repair and does not touch the app's code.

## Cost

## Remove an app

**Remove** revokes the app. It is paused first and kept for a retention period, so a mistake can be undone with **Keep it**. After that period the app and its cloud resources are removed.
