Monetizing your App Inventor applications can be effectively achieved by integrating Admob advertisements. Interstitial ads, a type of pop-up advertisement, can be disruptive if displayed immediately upon app launch. To enhance user experience, it’s advisable to implement a delay before these ads appear. This tutorial will guide you on how to seamlessly integrate Admob banner and interstitial ads into your App Inventor projects.
First, you will need to retrieve your Ad Unit ID from your Admob account. If you don’t have an Admob account yet, you’ll need to create one. For the purpose of this guide, we’ll assume you already have an active Admob account and are ready to implement ads.
Pasting Admob Ad Unit ID into the AdUnitID property field for each Admob component in App Inventor.
Once you have copied your Ad Unit ID from Admob, navigate to the properties section of each Admob component within your App Inventor project. Locate the “AdUnitID” field and paste the copied ID into this field. Refer to the image above for visual guidance.

With the Ad Unit IDs in place, proceed to the Blocks editor to configure the behavior of your Admob components. Construct your code blocks as shown in the image below. Feel free to customize the timing and ad display logic to suit your app’s design and user flow.
App Inventor blocks configuration displaying banner ad after 1 second and interstitial ad after 5 seconds upon screen initialization.
The block arrangement illustrated above will result in the Admob Banner ad appearing 1 second after the application launches (Screen1 Initialize event). Subsequently, the Interstitial (pop-up) ad will be displayed after a 5-second delay. You can now build your application project or test it in real-time using a USB connection to your smartphone for live testing.
Alternatively, you can implement the following block code structure. While functionally similar, some developers have reported better ad display consistency with this alternative configuration in certain scenarios.

Finally, and importantly, to ensure proper ad display and responsiveness across different devices, you need to adjust the screen sizing property for the screen containing the Admob components. Change the “Sizing” property from the default “Fixed” to “Responsive”. Refer to the image below for a visual guide on where to find this setting.

Just like with Adsense on blogs or YouTube, it is strictly against Admob policies to click on your own ads. Avoid self-clicking to prevent policy violations. This tutorial provides a straightforward method to integrate Admob into App Inventor. We hope this guide is helpful and enables you to successfully monetize your App Inventor applications.
