# Test Your Ads

Preview and verify ads configured in Helix before they go live, using the Ad Tester app.

The Ad Tester app lets you preview and verify ads configured in Helix before they go live.

## Download

* **Android** — [Get it on Google Play](https://play.google.com/store/apps/details?id=io.adn.sdktestapp)
* **iOS** — Coming Soon

## Scanning an ad

You need access to the campaign's ads in Helix. Allow camera access when prompted.

In Helix, open your campaign's ads listing. Tap an ad to enlarge its QR code. Open the Ad Tester app and tap **Scan QR Code**. Point your camera at the QR code.

Once scanned, the ad appears in the **Scanned Ads** list below, showing its creative name, campaign, format (e.g. Video Playable), and the date it was scanned.

To remove an entry, tap the delete icon.

## Previewing an ad

Tap any item in the Scanned Ads list to open the ad details page. Here you can review the creative name, associated assets (HTML and video files), and the exact scan timestamp.

To test the ad, select **Interstitial** or **Rewarded**. Tap **Load Ad**, then wait for it to complete. Tap **Show Ad** to render the selected placement.

If loading fails, enable **Debug Mode** in **Settings**. Retry the load and review the device logs.

## Settings

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.helix.voodoo.io/user-acquisition/create-ads/test-your-ads.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
