User feedback

Been working on an application for the three days then yesterday happened to present a demo to my target client base.
Me:I need you to go through the app and tell me your experience using it.
User: Great let me see it and comment on it.
Me:I wait patiently as he goes through the app asking for clarification on some activities .
User:I love it but I think would be nice if we improve on the following.
Me:Okay go ahead all ears.
User:How about on the share feature instead of sharing the apps link then one goes and downloads it and install,how about you simply share the APK and install it instant.
Me:Okay that's a good thought and later go on to explain to him why we share links as compared to sending the APK directly .
