Research
& Analysis



User Research                            
User Interview We asked 8 different users for taking some time to use old Sundan App, ‘how do they feel while using it’?



Pain PointsCluttered Interface Disorganised content, excessive sale tags, and poor visuals hinder navigation and product discovery.

Inefficient User Flows The absence of persistent, intuitive navigation makes it difficult to access key pages, disrupting the browsing experience.
Inconsistent Design Incoherent visuals and a lack of distinctive Sundan branding weaken brand recognition and user connection.
Limited Engagement A lack of product ratings, community features, and lifestyle content reduces user interaction and feedback.



The Challenge
Competitor Audits                    
This competitor analysis provided valuable insights into market trends, strengths, and weaknesses, offering a strategic path to enhancing the Sundan app's product experience.

Note: This project was conducted in 2022, with marketing content and customer experiences based on insights from 2021.




Opportunities for SundanMust-Have Features • Familiar UX/UI standards inspired by WeChat, with subtle enhancements.
• Integrated live-stream shopping mode for dynamic product discovery.

The Challenge
Usability Study                          
Findings The Usability Study provided key insights into the Sundan app's user experience, highlighting areas for improvement. These findings were categorised and prioritised to guide design enhancements.

The Challenge
Design Systems                        
The design system builds on Sundan's brand identity with a refreshed colour palette and updated icons to suit lifestyle content. Buttons were redesigned for intuitive function recognition.The system and guidelines were handed over for future development.

The Challenge
Mockups                                      

Home Designed around Chinese user behaviours, the homepage is structured into five key sections: News (Features trending updates, promotions, and live-stream access), Popular Categories, Offers, Shop by Brands, Top Sales. This layout ensures key content is immediately accessible, aligning with the preference for continuous scrolling. Categories A refined layout with a clear hierarchy improves navigation. The new hamburger button enhances product search efficiency for a smoother user experience. Sort & Filter Default filters offer more personalised and efficient search experience. Hamburger Button Provides quick access to categories after extensive scrolling.


Product Key information is organised within dropdown menus to prevent information overload. Customisable product options reduce the need for repeated searches.Ratings & Reviews A prominent button ensures users can easily access and explore detailed reviews.                                                                                                                                            

Basket The new ‘Customise Your Products’ function allows you to adjust the product before checkout. CheckoutNew ‘Add New Address’ and ‘Find a Store’ buttons improve usability, also allowing users to label addresses for easy identification.        
         



Discover Adopts a magazine-style layout with curated imagery and content across:
Stories, Buying Guides, Community, Classes & Events.
This immersive approach inspires users with lifestyle-driven content.                                                                                  
More Button Essential services, including ‘Discover’ and ‘Live Stream,’ are housed under the pop-up ‘More’ menu. Improved interaction design ensures smoother navigation, once users select ‘Discover,’ the ‘More’ icon updates accordingly for better page recognition. Community Encourages engagement through interest-based clubs. For example, the ‘Cooking’ club allows users to share recipes and cooking tips, with content easily shareable with friends and on social media.

Project
Overview

  Introduction  
Helping people build healthy habits that feel good, not forced.
Wellio blends warm microcopy, flexible interactions, and light-touch AI insights to make daily wellness feel personal and sustainable.
My Role: UX Research · UI/Interaction · Design System · UX Writing · Strategy · Brandin
Problem Most wellness apps lose users quickly because they feel demanding, data-heavy, and impersonal.Solution A warmer, more flexible experience that supports small daily actions through:
• Empathetic tone
• Adaptive, choice-based interaction paths
• Subtle AI personalisation to surface what matters
Designed to help users build habits that last.

Goals 1. Reduce cognitive and emotional load in daily logging
2. Personalise tools and content based on evolving user needs
3. Support habit continuity through small, confidence-building wins

Challenge “What if a wellness app felt more like a supportive companion than a tracker?”


000000
 Early Signals & Strategic Value  

Early walkthroughs showed clear promise:
• Small clarity fixes boosted confidence and reduced hesitation.
• Light-touch AI surfaced what mattered without adding pressure.
• Supportive tone encouraged users to return and stay engaged.


Together, these signals point to a warmer, high-trust experience that supports long-term habit continuity.

Early Feedback SnapshotUsers completed key tasks smoothly and felt reassured by clearer labels and a more supportive tone.



How AI SupportsLightweight grading, summaries, and tailored suggestions enhanced understanding without cognitive load.


Potential Business ValueSupportive guidance strengthens habit retention, deepens trust, and opens opportunities for wellness partnerships.

  About Testing  
Overview
5 remote participants tested the low-fidelity prototype.
Key tasks: logging breakfast, adding favourites, viewing stats, and exploring content.
Findings and insights directly informed the high-fidelity iteration.


See full testing details

(Includes five tester records with observations, feedback, and recommendations.)
Key Findings

 Key Learnings  
1  Real users reveal real gaps
Early feedback surfaced blind spots: unclear icons, missing confirmations, and confusion around AI cues.


2  Micro-frictions shape confidence
Even small hesitations (e.g., “Is this saved?”) influenced trust. Clear micro-interactions mattered more than expected.

3  Personalisation needs structure
Users liked choice, but only when guided. A light framework made customisation feel supportive, not overwhelming.


4  AI tone must be human
Participants preferred insights that felt simple, friendly, and emotionally aware, especially in wellbeing contexts.



000000
 Behavioural Insights  

The following behaviour patterns were observed across testing sessions. These insights informed the design tweaks made in the next iteration:
Users needed clearer ‘way back’ paths
Several weren’t sure how to return to Well Today or switch sections smoothly.
Icons without labels caused hesitation
Participants paused at buttons like “AI” or “Favourite”, unsure what they meant.

Raw data rarely led to action
Stats alone didn’t motivate behaviour: users wanted summaries, nudges, or small suggestions.

Customisation tools went unnoticed
Personalisation existed, but wasn’t always recognised without better visibility or grouping.

Instant feedback increased confidence
Small reassurances, ticks, toasts, shadows, helped users feel more “on track”.



000000
 Final Reflection  
This self-initiated project means a lot to me, both personally and professionally. I’ve always believed wellness design should feel personal, supportive, and accessible, and through Wellio I explored how tone, structure, and careful interaction design can reduce friction and make daily wellbeing feel more human.

Coming from a visual design background, going through the full UX process: research → testing → iteration, expanded how I think about product design. It wasn’t perfect, but it pushed me to grow in both craft and mindset. I’m proud of how far I’ve come, and excited to keep building, not just better design, but more meaningful experiences that genuinely support people.
