The Hopper app: a route-planning screen headed “start planning your route” with pickup and destination fields over a city map, flanked by a HOPPER-branded phone seen edge-on, a “TAXI!” speech bubble, a map pin, and an illustration of a blue car promoting the carpool scheme.

Three onboarding screens: asking for the rider's work address, then their weekday commute times, then an account registration form. How a trip is planned: a pickup pin joined by a dashed route to a destination pin with a blue car along it, beside the destination search, the map view, and a fare screen offering Carpool or Private. Two screens for buying shared-ride passes: a bundle picker offering eight tickets for $280 or sixteen for $500, and a trip detail listing the booking time, route, duration and a $290 total above a pay button. Dozens of the app's screens tiled at an angle across a blue field, with a HOPPER-branded phone standing in the middle of them. The design system sheet: the PingFangTC typeface in Light, Regular and Semibold, buttons in default, pressing, pressed and disabled states, text fields in default, focus, filled and error states, and the four-colour palette with its hex values.
