Is it possible to change the look of the user login screen & favicon so it's on brand with my course?

Hey Sam and the Team, I am thinking of moving over to Skool from Kajabi, but was wondering if you guys were working on a mobile app for students/clients to go through the modules on their phone? This is one thing I love about Kajabi because you can listen to courses on the go. I imagine you will be coming out with an app sometime in the near future?
