FitTrack is a Flutter mobile app concept for fitness and wellness, designed for Android and iOS. The app features personalized workout tracking, fitness progress analytics, nutrition and calorie tracking, user authentication, notifications, and a Firebase backend using Firebase Authentication, Cloud Firestore, and Firebase Storage. I designed the mobile UI/UX with a clean, responsive interface focused on usability, performance, and a scalable cross-platform experience.

Building PULS – A Cycling App That Makes Every Ride Worth Sharing
PULS is a dedicated cycling tracker designed for riders who want more than just numbers. It focuses on clean ride tracking, meaningful progress, and beautiful achievement cards that are ready to share.
The app lets cyclists track distance, speed, elevation, cadence, and duration in real time. After every ride, users get a clear summary and can turn their performance into a custom visual card — complete with route map, key stats, and personal highlights — then share it directly to Instagram, WhatsApp, X, and more.
How I built it:
Step 1.
I started by writing a detailed Product Requirements Document using Claude through MCP. This PRD became the foundation for the entire product.
Step 2.
I used Flowstep to generate the initial UI designs directly from the PRD. This gave me a complete starting point for the full user flow — from onboarding and live tracking to ride summaries and the achievement card editor.
Step 3.
I moved everything into Figma to refine the design system, improve visual hierarchy, polish spacing, and make every screen feel consistent and premium.
Step 4.
Once the designs were finalized, I brought them back into Flowstep to create interactive prototypes and validate the experience.
Step 5.
Finally, I used Claude via MCP again to help turn the polished designs and prototype into a working product.
The result is a focused cycling app that combines accurate tracking with a shareable, aesthetic layer that most fitness apps still lack.

Really like the focus on making each ride feel worth sharing, not just tracked. The achievement cards are a nice touch, and your workflow from PRD to Flowstep, Figma, prototype, and build feels very well thought out. Good luck
Bringing data to the deadlifts. 🏋️♂️ I just wrapped up the landing page for a brand new fitness app coming soon tailored for gym enthusiasts. The core concept is simple but powerful: giving users the ability to automatically log and save their workout sets straight into a sleek, manageable spreadsheet. Loved dialing in the design to make tracking as frictionless as possible. Check it out! 👇
