Hey @daveambrose ,
Thank you so much for your kind words and taking the time to check us out.
The reason we decided to do desktop first is cause people are use to buying things from online and seeing a "bigger picture" or getting a better overview of an item they are interested in.
Though mobile app is in production at the moment and we believe that the biggest use our users will get from it is listing items directly from their mobile device.
Again thank you very much for your time and joining with our platform.
If you have any other questions then please let us know.
