# Launch monitor

Use the launch monitor to track exposure and adoption, and to collect end-user feedback.

## Exposure

The Exposed chart shows the distinct count of companies that have been exposed to the flag. Exposed means they were checked for flag access in the SDK and the check returned `enabled`.

## Adoption

The Tracked chart shows the distinct count of companies that have interacted with the flagged workflow. Interactions are tracked with the `track` method.

```typescript
import { useFlag } from "@reflag/react-sdk";

function StartHuddleButton() {
  const { isLoading, isEnabled, track } = useFlag("huddle");

  if (isLoading) {
    return <Loading />;
  }

  if (!isEnabled) {
    return null;
  }

  return (
    <div>
      Huddles
      <button onClick={() => track()}>Start huddle</button>
    </div>
  );
}
```

## Feedback

You can collect end-user feedback on new flag rollouts to catch and fix issues faster.

### Static feedback button

Here's a brief example using the [Reflag React SDK](/supported-languages/browser-sdk.md) to collect feedback:

```tsx
import { useFlag } from "@reflag/react-sdk";

function StartHuddleButton() {
  const { isLoading, isEnabled, requestFeedback } = useFlag("my-flag");

  if (isLoading) {
    return <Loading />;
  }

  if (!isEnabled) {
    return null;
  }

  return (
    <>
      <button>Use huddle</button>
      <button
        onClick={() => requestFeedback({ title: "How do you like huddles?" })}
      >
        Give feedback!
      </button>
    </>
  );
}
```

### Automated feedback survey

Automated surveys let you ask for feedback at the right time after `N` interactions with the flag. [Learn more here](/product-handbook/launch-monitor/automated-feedback-surveys.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.reflag.com/product-handbook/launch-monitor.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
