Mobile module integration with Native App

Hello Everyone 

I am creating a OS-Mobile module and i would like to call it from another mobile app written in a native platform (android or iOS). Will it be possible ?

For example, I have a running version of mobile app developed in Xamarain, i wanted to enhance this application but enhancement will be done in Outsystem , i am not willing to write any more code in Xamarin. 

Thanks In advance for your support. 

Do you wish to expand your application by creating it as an Outsystems mobile application?
I don't think you will be able to combine them..... you might have to start from scratch in Outsystems.

Or are you thinking of expanding functionality using webservices?
For this you can create the webservices in Outsystems and call them from your native app.
