DAPPA Technologies

A virtual try-on product that started as a mobile app before pivoting to a Chrome extension after struggling with traction. I led UX/UI design across a team of 5 designers and 2 developers, shaping direction through multiple pivots before the company shut down following Google's entry into AI try-on.

Scope
Chrome extension, onboarding, design system
Problem
Online shoppers lack confidence in fit and sizing, leading to hesitation, regret, and high return rates. There was no way to visualise how clothes would look on you before buying.
Solution
I designed a Chrome extension that let users try on clothes virtually, track prices, and get sizing recommendations, all without leaving the retailer's site.

Approach

Research showed that fit uncertainty and lack of visual confidence were the biggest barriers to purchase.

Working in rapid build > measure > learn cycles, I focused the product around 3 pillars: virtual try-on for visualisation, price tracking to reduce hesitation, and social sharing to bring external validation into the buying process.

Challenge

The MVP worked but wasn't connecting with our female audience. The design was too minimal and generic, lacking the personality and polish needed to build trust and brand recognition. Initial usability testing also showed the 28-screen onboarding flow was the biggest drop-off point. I redesigned the flow around a few key changes.

Testing revealed…

Upload confusion
"So I need a full body
photo, then?"
Lost at launch
"I downloaded it but...
how do I open it?"
Discoverability
"I forgot I even had
it installed."
Created an improved sign-up flow for desktop
As we pivoted from app to Chrome extension, desktop gave us more screen space to build credibility through branding and visuals. Added a pin prompt during setup so users wouldn't lose the extension after install.

Streamlined photo upload
Users didn't know what type of photo to upload. Replaced the long and old tutorial video with inline photo guides showing exact requirements, and an auto-camera with real-time capture signals to reduce guesswork.

Shipped, tested &
pivoted

Direction shifted often as the business model evolved. These features were designed, but ultimately dropped as the business model and goals changed.

B2B dashboard

Built to win over retailers. Didn't gain traction, so we pivoted to B2C.

Wardrobe redesign

Cleaned up a cluttered wardrobe page.
Retention still struggled due to tech constraints.

Explore shop

Added in-app product search to drive affiliate revenue.
But, search relevance didn't meet the bar for useful product discovery.

Reflection

DAPPA shut down after Google entered the AI try-on market. In 1.5 years, I shaped product direction through multiple pivots, built a design system from scratch, and learned how to make fast decisions with incomplete information.

The biggest shift in my thinking was around simplicity. In a startup full of ambition, the instinct is to cram features into a product and ship fast, but I learned that slowing down to research and keeping flows lean saves more time than it costs. Towards the end, our Chrome extension was gaining real traction before the shutdown, which proved to me that this approach works.
