UX / PRODUCT DESIGN CASE STUDY
DayByDay Kids
Family Wellbeing Tracker
A mobile product concept helping parents capture small daily wellbeing observations and recognise patterns over time.
UX/Product Design · Mobile App · High-Fidelity Prototype · 2026
PROJECT OVERVIEW
Supporting the Small Things Parents Notice
Parents often notice small changes in their child's mood, sleep, energy, appetite or minor symptoms throughout everyday life.
These observations can be easy to forget, especially when they happen across busy days. When parents later need to share information with a teacher, caregiver or health professional, they may have to rely largely on memory.
DayByDay Kids was developed as a simple, supportive way to capture these small daily observations and recognise patterns over time.
THE OPPORTUNITY
Create a lightweight place for everyday wellbeing tracking — without making the experience feel clinical or complicated.

Making Everyday Tracking Feel Effortless
PRODUCT DIRECTION
The concept was built around a simple idea: recording a small wellbeing observation should take seconds, not feel like another task for a busy parent.
Instead of detailed health logs or complex dashboards, DayByDay Kids focuses on lightweight daily check-ins. Parents can capture changes in mood, sleep, energy, appetite and minor symptoms through simple interactions, then use weekly summaries to recognise patterns that may otherwise be difficult to remember.
The experience was intentionally positioned as a daily companion rather than a medical tool. This influenced both the functionality and visual direction — keeping interactions simple, language supportive and information easy to understand.
THE PRODUCT PRINCIPLE
Small observations, captured consistently, can create a clearer picture over time.

FEATURE PRIORITISATION
From Possibilities to a Focused Product
FEATURE PRIORITISATION
From Possibilities to a Focused Product
DayByDay Kids had the potential to grow into a much broader family wellbeing platform, with features ranging from reminders and editable entries to multiple child profiles and more detailed tracking.
To keep the experience lightweight, I prioritised features based on how directly they supported the product’s main purpose and how frequently they would be used. The focus became the actions parents would return to regularly: daily wellbeing check-ins, symptom tracking and weekly summaries, supported by simple sign-up and personalisation.
Other functionality, including reminders, editable past entries and multiple child profiles, was kept secondary. These features could add value later, but were not essential to the core experience.
This helped keep DayByDay Kids focused on a simple idea: make it easy to capture what is happening today and turn those small observations into something meaningful over time.
INFORMATION ARCHITECTURE
How content and functionality are organised.
INFORMATION ARCHITECTURE
Turning Structure Into a Clear Journey
Once the core functionality was defined, I organised the product around the actions parents would need most often.
The information architecture separates onboarding, authentication, the main app and account management, while keeping daily check-ins, symptom tracking and weekly summaries at the centre of the experience.
From there, I mapped the user flow to understand how these areas connect in practice — from creating a profile and reaching the home dashboard to recording observations, reviewing trends and managing account settings.
Together, these helped turn the feature set into a clear structure before moving into interface design.
USER FLOW
How users move between key actions.
FROM STRUCTURE TO INTERFACE
Exploring the Experience Before Visual Design
Before moving into the high-fidelity interface, I translated the product structure into simple mobile flows.
Early sketches helped establish the placement of key actions and information, while low-fidelity wireframes allowed me to refine sign-up, navigation and everyday tracking without being distracted by visual styling.
At this stage, the focus was on clarity, hierarchy and reducing the number of steps needed to complete common actions.

FINAL EXPERIENCE
Designed for Everyday Use
The final interface brings the core experience together in a calm, lightweight product designed around everyday family routines.
Quick check-ins make it easy to capture changes as they happen, while symptom tracking and weekly summaries turn individual observations into a clearer picture over time. Soft colour, clear hierarchy and familiar interaction patterns keep the experience supportive rather than clinical.

DESIGN RATIONALE

Designing for Clarity & Comfort
DayByDay Kids deals with personal wellbeing information, but the experience was intentionally designed to feel supportive rather than clinical.
Soft colour, familiar interaction patterns and clear visual hierarchy help reduce complexity, while important information remains easy to identify and understand. The interface was designed around quick everyday interactions, allowing parents to record observations without navigating through dense screens or unfamiliar controls.
Accessibility was considered throughout the visual design, with an emphasis on readability, simple language, comfortable touch targets and visual cues that do not rely on colour alone.
READABLE CONTENT
Clear hierarchy and legible text.
SIMPLE LANGUAGE
Direct, familiar wording.
TOUCH-FRIENDLY
Controls designed for comfortable
interaction.
BEYOND COLOUR
Labels and visual cues support meaning.
REFLECTION & NEXT STEPS
Simplicity is about deciding what deserves attention.
DayByDay Kids reinforced the importance of designing around everyday routines rather than simply adding more functionality.
The challenge was to make daily observations meaningful without turning the experience into a complicated health tracker. Keeping interactions quick, information clear and the visual language supportive helped the concept stay focused on that purpose.
NEXT STEPS
The next step would be to test the prototype with parents, focusing on the daily check-in and whether weekly summaries make patterns easy to understand.
