Consumer facing multi-platform golf app

An app for golfers to make golf reservations, reserve rooms, and buy products.

Refer to branding guide attached. App should be simple, modern, and clean - not cluttered. I prefer a darker theme and would even more prefer submissions that include both dark and light themes. Designs should be aimed at personal iOS and Android phones in portrait mode only.

Apart from the navigation widget, I would also appreciate additional icons that we can use in future phases of this project, like maybe an alert bell showing how many messages you have or an icon that allows you to change your current golf course.

Screen 1 - Login/Register, Login with Google/Facebook general form screen

Screen 2 - Tee Sheet - grid of tee times available for golfer to play, each box in grid should have something like:
3:10 PM
$55.00
2 slots available
*use space wisely here, we want to fit as many times as possible on the tee sheet without it feeling "cramped"
* I'm open to a "row" format instead of a grid if it looks better

Screen 3 - Tee Time Details - beautiful image of golf course, details about the tee time including pricing, instructions from the course, etc. Should have "add to cart" and "reserve" buttons

Screen 4 - Shopping Cart - should show a list of all items currently in shopping cart

Screen 5 - Checkout - order details, totals, choose payment method, "place your order" button

screens 2-4 should have universal navigation to "Shop", "Hit Balls", "Get a Room", and "Play Golf"

I don't like "pill" buttons, I like square buttons with a slight curve. This app will run on Android and iOS
