Design is a complicated art and all my experience in building mobile apps just allows me scratch the surface. I still made an effort today to come up with some wire frames. Here are my thoughts

As a developer I think too much when I design, I am already thinking about the solution and it kinds of clutters my mind a lot
I have to keep telling myself it is just to give shape to whats in your head.
AdobeXD has been a great tool for this. The 9.99$ investment looks to be useful for now. I found this template for wireframes. Looks cool too
I have come up with 6 screens for now, the main ones are;
Landing screen - I want a background video floating on it with the registration and login options on the bottom. I will need to get some stock footage for that
Registration - keeping it simple right now with Email only option as facebook or google could be added beyond the MVP
Movie Feed - I wanted to have larger posters but, kind of sucks that no one gives you access to these in their API's. I want to keep information simple for now
