Build a Fitness Tracker with Next.js
A workout tracker with exercise logging, sets/reps, and progress charts. Using Next.js's Next.js 14+ with App Router, SSR, and shadcn/ui, LoomCode AI generates a production-ready fitness tracker with clean code structure, proper state management, and a polished user interface — all from a single text description in seconds. No prior coding experience required.

Why Build a Fitness Tracker with Next.js
A fitness tracker needs to be intuitive and responsive. Next.js's component model lets you build distinct sections (tracking, visualization, input) as isolated, reusable pieces.
What the AI Generates for This Fitness Tracker
- Responsive fitness tracker layout that adapts to desktop, tablet, and mobile
- Component-based architecture with reusable UI elements
- Client-side state management for instant user interactions
- Styled with Tailwind CSS utility classes for a polished look
- Data visualization with trend lines and goal indicators
- Privacy-conscious input forms for personal fitness tracker data

What You Get
LoomCode AI generates a fitness tracker with data input forms, trend visualizations, and goal tracking. Charts show historical data with trend lines, and progress indicators compare current values against targets. The output is properly structured Next.js code using Next.js 14, TypeScript, Tailwind CSS, shadcn/ui with typed components, responsive styling, and clean state management. The app runs immediately in a live sandbox — interact with it, test every feature, then iterate with follow-up prompts or deploy to a shareable URL.
Tips for Better Results
- Describe the data you are tracking: "weight, blood pressure, steps, calories" with input method (manual entry, slider, date picker)
- Ask for trend visualization: "line chart showing last 30 days, moving average, goal line overlay"
- Include "daily/weekly/monthly views" and "goal setting with progress percentage" for a complete tracking experience
- Consider asking for responsive design explicitly if mobile support matters for your fitness tracker

FAQ
Can AI build a Fitness Tracker with Next.js?
Yes. LoomCode AI generates a complete fitness tracker with Next.js 14, TypeScript, Tailwind CSS, shadcn/ui from a text description. The AI understands personal data tracking, visualizations, and goal monitoring and produces working code that runs immediately in a live sandbox. Next.js's component architecture handles personal data tracking, visualizations, and goal monitoring with reusable UI pieces and efficient state management. You can iterate with follow-up prompts to refine features or deploy with one click.
How long does it take to build a Fitness Tracker with AI?
A working fitness tracker typically generates in 30-60 seconds. The initial version includes personal data tracking, visualizations, and goal monitoring with a polished UI. From there, you can add features incrementally — each follow-up prompt takes another 15-30 seconds. Most users go from idea to a deployable fitness tracker in under 10 minutes, compared to hours or days of manual development.
Can I customize the generated Fitness Tracker?
Yes, in two ways. First, use natural language follow-up prompts: "add dark mode", "change the layout to tabs", or "add a search filter" — the AI modifies the existing code. Second, copy the full source code and edit it directly. The output is standard Next.js code using Next.js 14 and TypeScript that works in any React/Vue/Next.js project.
Which AI model works best for a Fitness Tracker?
For a fitness tracker, GPT-4o offers the best speed-to-quality balance for quick iterations. Claude 3.5 Sonnet produces more polished code for complex features. DeepSeek V3 is a cost-effective alternative for simpler versions. You can switch models anytime.
Is the generated fitness tracker production-ready?
For prototypes and MVPs, the generated fitness tracker is typically ready to use immediately. The code includes proper TypeScript types, component structure, and responsive design. For production deployment at scale, you may want to add automated tests, error boundaries, and monitoring.
