Jimmy Brings redesigned home screen on iPhone, with horizontal category lanes and a brighter palette.
Product · 2020 · early-career

A Jimmy Brings home screen that surfaces the full range, without growing the app.

I redrew the e-commerce flow from research to final. Single-axis scrolls gave way to multi-axis browsing that lets 104 products read like a real range.

Brief

An innovative solution to the Jimmy Brings e-commerce app, shaped by quantitative and qualitative research. Modern, usable, and desirable for the user.

Problem

The original home screen used single-axis scrolling with category drop-downs, so the full catalogue stayed buried. Heavy type and dark surfaces pushed against the premium positioning. The range read as thin even though there were 104 products on offer.

My role

Sole designer on a self-directed end-to-end exercise during my UX/UI postgraduate year:

  • Quantitative and qualitative research with target users
  • Four personas drawn from interviews and questionnaires
  • Affinity mapping across Jimmy Brings and Uber Eats
  • UI flow, ideation, low-fidelity wireframes
  • Colour, typography, iconography
  • A/B testing of two home-screen architectures
  • High-fidelity final and prototype hand-off
Outcome

A premium feel, with the full range surfaced in a single scroll.

Current interface

Single-axis scroll with category drop-downs underneath. Quantity selection was simple and worked. Heavy type and dark surfaces pushed against the premium feel. The payment screen, by contrast, was efficient.

UI flow

The end-to-end app flow: age-gate, login, home, category, product, cart, payment, and live order tracking. Mapping it in one view made it clear the home screen was carrying too much of the navigation work.

Landscape review

Three e-commerce apps reviewed. Wide reading on layout types — landing and product page focus.

Uber Eats

Multi-axis scrolling — users move effortlessly between categories. An app the Jimmy Brings demographic already knows.

Affinity map

Observation, interviews, and usability testing on Jimmy Brings and Uber Eats. Three clusters carried the weight: navigation friction, perceived range, and category visibility.

Themes: navigation, range, visibility.

Insights

From interviews and the affinity-mapping process:

  • "No back button." Moving between categories meant scrolling all the way back up.
  • "Limited offerings." 104 products, but the layout made it feel thin.
  • "They could use multi-axis scrolling like Uber Eats." Show range, prompt impulse buys.
  • "That category should be highlighted from one to another." Visible variety.
  • "I like scrolling — it's what I'm used to." Keep the gesture familiar.

Personas

Four personas representing the Jimmy Brings target market — updated through the design process and revisited at every decision point.

Persona Sam, 22, Sydney: party top-up buyer happy to pay delivery to stay with mates.
Sam, 22 — pays delivery to stay at the party.
Persona Will, 26, CBD: time-poor weekday user who switches categories quickly.
Will, 26 — wants to switch categories fast.
Persona Sarah, 23, Bronte: host buyer ordering large evening rounds for the group.
Sarah, 23 — large host orders, splits the bill.
Persona David, 40, Paddington: quality-led buyer who wants premium feel and a wider range.
David, 40 — quality-led, wants the range to feel premium.

Ideation & low-fi wireframes

Two home-screen architectures came out of ideation — one vertical, one multi-axis. Both taken to low-fi so I could test them on real devices.

Variant A wireframe: vertical category list.
Variant A — vertical category list.
Variant B wireframe: horizontal chips with multi-axis product lanes.
Variant B — horizontal chips, multi-axis lanes.

Colour, typography, iconography

Brand purple as accent; surface to white. Lighter body type for legibility on long category lists. Iconography minimal — hamburger, cart, back chevron.

A/B testing

Both variants tested on target users: find a specific bottle, then browse for something for a party. Variant B (multi-axis) won on both. It carried into the final design.

Final design

Multi-axis lanes on the home, lighter typography, brighter palette, and a back-button pattern that respects how users move between categories.
