For security reasons, because of a dangerous attack vector, we decided not to allow installs outside of the Google and Apple stores. On top of that our app relies on Google and Apple services for push notifications, so it'd be a significant re-write of code to do so. I completely understand the request, and we'll consider now and in the future, but to be honest it isn't high on our priority list currently (managing expectations).

Thank you!
