DK / ENERTRACK02Overview
ONE PRODUCT.
MANY SIGNALS.
ONE CLEAR SYSTEM.
Enertrack brings activity, steps, calories, sleep and training into one flexible experience. I owned the full design cycle—from market and user research to product structure, high-fidelity UI and the final handoff to development.
UX direction
Information architecture, core user flows, low-fidelity wireframes and prototypes.
Product UI
Visual identity, interaction design, UI kit and reusable design system.
Delivery
Assets, documentation, specifications and component guidance for developers.

03The challenge
FITNESS PRODUCTS OFTEN GIVE PEOPLE MORE DATA THAN CLARITY.
The product had to enter a highly competitive market and serve users with very different experience levels. It needed enough depth to be useful without repeating the overload, restrictions and complexity people disliked in existing fitness apps.
Create an intuitive MVP with a clear visual structure, flexible data priorities and motivation tools grounded in real user needs—then prepare it for a smooth development handoff.
04Research
UNDERSTANDING WHAT KEEPS PEOPLE MOVING.
I benchmarked six direct and indirect competitors, then recruited participants through fitness communities on Telegram, Reddit and Instagram and conducted around 10 in-depth interviews about tracking habits, frustrations and motivation.
DK / ENERTRACKClarity beats metric depth.
Irrelevant advanced metrics, complex features and advertising made tracking feel harder than it needed to be.
Progress needs reinforcement.
Personal goals, visible progress, virtual rewards and non-intrusive reminders helped users maintain momentum.
Sharing should stay optional.
Most participants tracked progress privately, while some wanted a simple way to share results with friends or coaches.

05Process
FROM INSIGHT TO A DEVELOPER-READY PRODUCT.
Research became a clear information architecture, then low-fidelity wireframes and an interactive prototype. Each stage reduced uncertainty before the interface moved into high-fidelity design.
DK / ENERTRACK
DK / ENERTRACKDefine the product structure.
I translated research and requirements into information architecture and the core user flows.
Work in low fidelity first.
Wireframes made it possible to test hierarchy and functionality before investing in visual detail.
Prototype the critical journeys.
An interactive Figma prototype exposed usability issues early and helped refine the main flows.
Keep development in the loop.
Regular reviews, component logic and documented specifications reduced ambiguity during handoff.
Key design decisions
THE DIFFICULT PART WAS DECIDING WHAT NOT TO SHOW.
Protect beginners from overload.
The core experience stays simple, while more advanced functionality can be discovered over time.
Prioritise essential analytics.
I focused the main views on steps, calories, distance and heart rate instead of dense dashboards.
Make motivation tangible.
Achievable milestones and rewards give users a reason to return without relying on intrusive prompts.
Design with implementation in mind.
Prototype reviews and clear component documentation kept design decisions aligned with development.
06Product solution
DESIGNED AROUND THE NEXT USEFUL ACTION.
The solution prioritises the information people need now, while keeping deeper statistics and motivational tools one clear step away.
01 / DASHBOARD
A HOME SCREEN THAT ADAPTS TO THE USER.
A flexible dashboard lets people prioritise the metrics that matter to them—from activity and running to sleep or weight tracking.
- Prioritised metrics
- Personal goals
- Clear daily progress
DK / ENERTRACK02 / INSIGHTS
STATISTICS THAT EXPLAIN PROGRESS.
Customisable filters turn raw measurements into a readable story, while optional sharing supports users who want external motivation.
- Flexible date filters
- Focused key metrics
- Optional sharing
DK / ENERTRACK03 / TRAINING
GUIDANCE WITHOUT LEAVING THE PRODUCT.
Filters help users find relevant video workouts, and detailed screens keep the timer, description and preview in one clear flow.
- Workout filters
- Video preview
- Timer and guidance
DK / ENERTRACK04 / MOTIVATION
SMALL WINS BUILD A REASON TO RETURN.
A reward-based path turns long-term goals into achievable milestones and recognises progress without adding pressure.
- Achievements and milestones
- Visible progress
- Non-intrusive notifications
DK / ENERTRACK07Design system
BUILT TO GROW BEYOND THE MVP.
I defined the visual identity, typography, hierarchy, reusable components and documented states. The UI kit gave the team a consistent foundation for the MVP and future product development.

08Outcome
DESIGN CONNECTED TO PRODUCT RESULTS.
Active users in the first two months
Increase in user retention
Investment secured
Final outcome
The outcome went beyond the interface: the MVP improved engagement and retention, secured business support, and gave the team a reusable system and clearer handoff for continued product development.
