## 1. Install from Google Play

CatSuite is free, with no subscription and no paywall. [Get it on Google Play](https://play.google.com/store/apps/details?id=br.com.netcattest.catsuite.app) and open the app.

## 2. First launch

On the home screen, tap **START**. On first access, the app shows the terms of use and the module selection. You can enable History, Notepad, Discoverer, SSL/TLS Analyzer and Network Proxy now or later in **Settings**.

## 3. Main navigation

The bottom bar has three entries:

| Entry | What it opens |
|---|---|
| INTERCEPTOR | Intercept, History, Site Map and module options |
| BROWSER | The lab’s technical browser |
| MENU | Additional modules: Repeater, Intruder, Discoverer, History, Notepad, Decoder, SSL/TLS Analyzer, Network Proxy, Settings and Extensions |

## 4. Capture your first request

1. Open the **Browser** and visit an authorized target.
2. Go back to the **Interceptor** and open **History**.
3. Tap a request to see headers, body and response.
4. Use **Repeater** to resend with changes or **Intruder** to test variations.

> [!TIP]
> In Intruder, add `$CAT$` to the request to mark where the wordlist will be applied.

## 5. Export evidence

History can be exported in the formats below. Exporting and sharing always depend on your action.

| Format | Content |
|---|---|
| TXT | Complete history as organized text |
| cURL .txt | Complete cURL commands, including `-X`, `-H` and `-d` |
| JSON | Structured data for analysis and automation |
| .HAR | File compatible with HTTP traffic analysis tools |

## 6. Protect the session

In **Settings** you control biometrics at launch, inactivity lock and screenshot protection.

## Next step

Once you master the modules, turn your routines into code: [CatSuite extensions](https://netcattest.com/catsuite/en/docs/extensions).
