A Canadian company with an established successful business in selling luxury cars on a global market.
BlackGear App should enhance and speed up trading experience amongst existing users, as well as attract new ones.


The company has a large base of vetted users, who all currently trade and conduct their business through the company’s liaisons.
In order to reduce costs, enhance the experience, speed up and modernize the process of luxury car trade, an app is needed.
The app must have a strong UX that carers to global needs and unify amenities from different markets. For example, the standard for displaying prices of luxury vehicles differs from market to market, users from various markets act, think and decide on their purchase differently, and not to mention – they like different things.
The app must successfully unify both the buying and the selling experience, including the creation of the ads and entering all the possible vehicle information without overwhelming the user; it must enable clear and coherent communication between users, display price breakdown in a way that is clear for every user type, regardless of their market; and provide all the user history and financial data possible. The vehicle ads must display all the vehicle information in a clear, organized and easy to scan through manner, while not allowing potentially low-quality, user provided photos to spoil the visual impression.
The UI must stand out from other apps, yet still look familiar.


The design process started out by thorough market research, testing out experiences on similar platforms and noting their positive and negative sides. The app requirements were thoroughly investigated, reorganized and divided into four main areas: buying, selling, communication/chat and profile information, which became bottom menu items enabling users to navigate through the app and start wanted experiences.
This was followed by designing a rough outline of various possible user flows in order to define the required app screens and their interconnectivity.
After confirming the screens scheme, a hi-fi wireframing process for each screen began. A lot of thought was given to unifying, yet differentiating buying and selling experiences, which were eventually designed to resemble each other in layout and color, but with notable differences in key screen positions – the buying experience features a search bar at the top, while the overview of sold cars shows tabs for navigating between your active, expired, sold and drafted ads.
Creating an ad was divided into 4 main steps, the first one being entering general vehicle information (with the ability to prepopulate majority of required fields if the correct VIN number is provided), the second one breaking down vehicle price in a way that is understandable to all markets, the third one allowing to determine ad details such as duration, acceptable payment methods and the ability to start an auction, while the fourth and last step was designed to attach photos to the ad.
The communication between users was based on a chat experience, which was clean enough for American and European users, but with a lot of available emoticons and stickers in order to cater to Chinese and Japanese markets.
Profile section contained the history of sales and purchases, a wishlist, a detailed financial overview of income and outcome, security settings and profile information.
The app UI was designed to give the users a premium, luxury feeling, whilst not overwhelming them visually and allowing the app data to be the focal point of the screen.
