Your mobile applications can be published as paid instead of free. Paid apps charge each user before download whereas free apps can be downloaded without any cost. 

In order to publish a paid mobile app, you firstly need to create your own developer accounts (in case you already haven't) and properly set them up in a way that you can receive payments. Subsequently, you will have to provide access to Looksomething so that mobile apps can be uploaded and submitted to your developer account.

Unfortunately, for the time being, we cannot undertake the development of mobile applications that include in-app purchases.
