The most important features the project owner requested:

1. Users/employees should be able to see their sale progress in a “ring” display such as on the “Fitness+” app
2. Users/employees should be able to have easy and fast access to all screens with information besides the “ring” display
3. Users/employees should be able to see the data for each of the four sales statistics (Mc Care+, Service Revenue, 3 PP Revenue, and Total Revenue)
4. Design of simple notifications that deliver timely, high-value information and enable important actions

The watchOS app experience differs from app experiences on other platforms in two primary ways:

1. Apple Watch is designed to be worn, so the UI is attuned to wearers and gives them an experience that’s lightweight, responsive, and highly personal.
2. People frequently use a watchOS app’s related experiences — such as complications, notifications, and Siri interactions — more than they use the app itself.

Because the “users/employees should be able to have easy and fast access to all screens with information besides the “ring” display” feature was quite important, I opted for a vertical type of “Page-based navigation”. I also wanted to bypass the “parent-child item relationship” as it would have been an additional step.

Page-based navigation is a way to present a flat collection of information in which all items are peers. In page-based navigation, each item is displayed on a single page. People swipe horizontally to navigate from page to page, and dots indicate their place in the set of pages.

For the user interface, I followed Apple's human interface guidelines for watchOS.

Design Fundamentals I followed:

Target a single feature or task. When you keep your experience tightly focused on an essential task, and display only the most relevant and actionable information, you give people the content they need every time they raise their wrist.

Enable quick interactions. Interactions with Apple Watch are measured in seconds, so your app must quickly give people the information they care about the most. Aim to present critical items in quick, glanceable interfaces, such as complications and notifications.

I did not include a launch screen.
Apple Watch interactions are brief and focused, and people expect to view their content immediately.

I did not display the MCShark logo in the app. I found the best use of screen space by displaying content instead of nonfunctional branding elements.

I expressed the brand's identity through font, accent color, and icon choices. These elements and icons I used let me create a unique visual style without making the app appear busy or complicated. The colors were selected from MCSharks brand to better distill the brands visual identity into the app.

I used a plain black background. I avoided filling background areas with brand colors and applied colors to specific elements instead. A solid black background reduces visual noise and improves the legibility of text.
