The app combines personal insights, smart tracking, and community features to create a well-rounded and motivating experience. Both light and dark UI themes were designed to adapt to different user preferences, ensuring usability and visual clarity in any context.

Blaze is a modern fitness app that helps users track physical activity, monitor heart rate, analyze sleep, and stay on top of their health goals — all in one place.

Blaze – Smart Fitness Tracking in Light & Dark Mode 🚀 1

What I Did as a UX/UI Designer

This project was created from the ground up — starting with research and ending with a fully responsive interface, design system, and interactive prototype.

Key areas of work included:

User Experience Research – Explored user needs and habits to define an intuitive and motivating app flow.

Branding & Visual Identity – Designed the logo, typography, and color palette featuring a signature orange accent to reflect energy and movement.

UI Design (Light + Dark Modes) – Developed two visual themes for maximum flexibility. Light mode keeps things bright and energetic, while dark mode offers a focused, immersive look ideal for nighttime or low-light use.

Health Dashboards & Data Visualization – Designed screens for activity tracking, heart rate zones, and sleep analytics with custom charts and clear data presentation.

Community & Personalization Features – Built out a social feed, onboarding flow, and personalized goal-setting features to keep users engaged.

Design System – Created a modular, scalable component library to maintain consistency and support future growth.

The Final Result 🎯

Blaze offers a refined, data-driven fitness experience that feels approachable and powerful at the same time. The interface balances structure with energy — from onboarding to in-depth stats — and supports users in building lasting habits through smart tracking and social motivation.

Both the light and dark modes are carefully designed to maintain clarity, accessibility, and style across all screens and user flows.

Great UI, Lika.

App looks really nice and feels pleasant to use. At first glance, the colors seem to have enough contrast in both light and dark mode, which is great.

I’m curious to learn a bit more about the “Your daily goals” module. At first, it’s not completely clear how it works or what exactly is included in it. As a user, I can see the 90%, but I’m not sure what that 90% actually represents. You might want to make this part a bit more transparent so users clearly understand what they are progressing toward.

I’m also interested in how you researched user habits. You mentioned this in your description, and I’d love to see that part documented in more detail if you have it.

Overall, the app looks really good. Congrats!


The Blaze app feels super fresh, informative, and clean, Lika! I love that you’ve converted it to dark mode, and overall it feels like a really modern, user-friendly experience. Great work!


Visually, the project looks solid. 💪 Dark mode is consistent, light mode also looks good, and the orange accent works great as an energy color. The overall aesthetic is clean and modern. Charts and data visualization are readable, which is essential for a fitness app.

The home dashboard has good information hierarchy. The progress ring draws attention as the main element, metrics are logically grouped, and the daily goals section naturally guides the user down the screen. The challenge banner nicely breaks up the data monotony.

This is a really good, complete project with a well-thought-out design system and cohesive visual identity. Professional approach and attention to detail are evident. Great job! ❤️🙌


What an incredible piece of work, Lika. The information hierarchy, color choices, and overall app structure feel very consistent. I loved it — let’s connect and exchange experiences!


This looks really great! Very clean UI, good use of color, and very professional presentation of your wireframes. I personally would have liked to see more of the process (sketches, ideation, design rationale, etc.) and have the Figma file attached so you can show off everything + how you organized your layers.

Keep up the awesome work!


Hey Lika!

I just checked out your Blaze Smart Fitness Tracking project and I think you did a great job, especially with the light and dark mode execution.

The visual consistency between both themes is really strong nothing feels like an afterthought. I like how the dark mode still maintains clarity and doesn’t sacrifice readability, which is often a common issue. The data visualization also feels clean and motivating, which fits well with a fitness product.

If I had one suggestion, it would be to push the interaction layer a bit more. For example, how do micro-interactions, progress animations, or feedback states enhance the motivation aspect? Since fitness apps rely heavily on engagement, showing that layer would make the project even more compelling.

Overall, very polished and visually cohesive work. You clearly paid attention to system consistency 👏


Beautiful project
