Hi, Abhishek!

Go to the first page of your mobile app and select the Distribution tab. Then choose the buttons Generate Android or IOS.

Hope it helps!

Hi Abhishek,

you can easily generate and distribute mobile apps following this steps:

First, go to "distribute" section of you mobile app in service studio, you will have two options to use the application, Native Platform and Progressive Web App:

• The Native Platform option is used by phone devices, so if you wanna use the application in your mobile devices just click in "generate android app", since IOS apps can only be generated if you have the Apple Developer Program puschased. You have more information in this article: https://success.outsystems.com/documentation/11/delivering_mobile_apps/generate_and_distribute_your_mobile_app/more_information_on_generating_and_distributing_mobile_apps/
  
  Once the application is generated, just scan the QR, it will redirect you at a  similar page:
  
  Here, you will be able to install the application you generated previously.

• Also, you have the option to use this application in your desktop, just by enabling the "Progressive Web App (PWA)" option
  
  Once it is enabled, open your app in your browser and click in "View in browser" button that is above of the app preview
  
  You will see something similar like this, then just click in this button and you will have the option to install the app in your desktop:
  

Kind regards,

Sergio
