Hey @Justin Ramos I'd be a good user for the app after watching the videos and seeing the website, here's my feedback:
1. First and foremost, the beta testing app within an app thing (iOS) is a major barrier to entry for me psychologically. I think your target audience is exhausted enough by the overwhelming process of shopping and may be hindered by the inability to download directly either for the sake of time and energy or the disappointment of feeling like it's gonna be a crappy beta that won't be around a long time.
2. I disagree with the idea that the sign up screen needs more. I think it actually needs less! I would minimize the entry screen to just launch into either a new account creation or interactive styling. The account sign up should just ask for the required info and either search for existing accounts with matching info or offer a small button with the sign in link. Alternatively, letting people try out the app should be the easiest way to get people involved right away. Launching right into the what are you looking for page can get people invested up front, then when they are ready to save, buy, or upload more information, they should be prompted to create an account. Loss aversion has gotten me to create accounts for dozens of sites I don't even like or remember.
3. Assume your customers are serial shoppers. They probably have full abandoned carts at 5+ stores and tons of inspiration pins they're looking to emulate. They probably have variations of their desired outfits already picked out, but haven't pulled the trigger. Offering a fast, all in one solution could be a huge draw. If I like the boots I saw hailey Bieber wearing, I want to feel confident I've seen everything available on the internet before I commit to a purchase, especially if I'm investing more than like $20
