Joining the AI Cross-Platform Challenge: Building a Smart Fitness Companion App with Uno Platform

I’m officially participating in the AI Challenge for Cross-Platform Apps, and I’ll be building a Fitness & Wellness Companion App using Uno Platform, enhanced with AI-powered insights.

This post is just my initial announcement before I publish my full submission.

💡 What I’m Building

I’m creating a cross-platform fitness app that works on:

• Web (WebAssembly)
• Windows
• Android
• macOS (optional based on time)

The app will include:

• Daily workout routines
• Water intake tracker
• Step counter simulation
• AI-generated workout suggestions
• Mood & wellness tracker
• Clean, modern responsive UI

I’ll be using Uno Platform, .NET, and the Hot Design Agent to co-design and rapidly adjust UI in real time.

🏗️ Why a Fitness App?

Fitness apps have a lot of visual and interactive elements — perfect for showing the power of Uno Platform and AI-assisted UI design.

I want the UI to feel minimal, modern, and motivating.

🔧 Tech & Tools

• Uno Platform (Multi-platform app)
• C#
• XAML
• Hot Reload
• Hot Design Agent AI
• .NET 9

🚀 Stay Tuned

I’ll post my final submission with:

• demo
• screenshots
• Hot Design Agent usage
• code repo
• design reference very soon!
