FWIW, I disagree this your leading statement -
I think that a lot of people generally take a service without an app
less serious. Their engagement is way lower, many times simply because
Even though I have 102 apps installed on my phone, I am very particular on which apps I install mostly because I obsessed about not sharing as much personal analytics as possible. The very nature of apps forces me to participate at that level. As an example, on my mobile, I would never use a Gmail app or Facebook. I try and access as much as possible through a browser.
In fact, if the CAKE honchos did deliver a Android app, I would not install it. I would always access via web browser.
So, not trying spew animonsity, but, I felt I needed to share my opinion as well.
