The Solid Man® App: A Development Journey with Flutter and AI Tools

Building a Men’s Development App

I recently completed the Solid Man® app – a mobile application that digitizes Ken Curry’s 5-Pillar process for men’s personal development. The app provides structured content for men working through issues like porn addiction, anger, and relationship struggles.

What the App Does

The Solid Man® app includes:

5 Pillars with 20 chapters of content
Audio narration for all chapters
Interactive questions (text, scale, and multiple-choice)
Progress sync across iOS, Android, Mac, and Windows
Account-based note-taking and progress tracking

Technical Implementation

Development Tools

I built this app using:

Flutter for cross-platform development
Claude Code and Cursor for AI-assisted coding
Firebase for authentication and data storage

Why These Tools

Flutter made sense because:

One codebase works on all platforms
Good performance on mobile devices
Decent documentation and community support

Claude Code + Cursor helped with:

Writing boilerplate code faster
Debugging common Flutter issues
Implementing UI components

Key Features

Audio Playback

Users can listen to content while driving or exercising. This required implementing background audio support on both iOS and Android.

Question System

The app parses markdown content with embedded questions and renders appropriate input widgets:

// Simple example of question parsing
Widget buildQuestion(Question question) {
  switch (question.type) {
    case 'multiline':
      return TextFormField(maxLines: 5);
    case 'scale':
      return Slider(min: 1, max: 10);
    case 'multi-select':
      return CheckboxList(options: question.options);
  }
}

Content Management

All content is stored as markdown files, making it easy to update without rebuilding the app.

Current Access Model

The app is free to download with an introduction chapter. Full content requires an unlock code, currently available only to members of Ken Curry’s Solid Man® groups. Public access is planned for a future update.

Development Insights

Using AI tools changed my workflow:

Faster prototyping – Claude helped generate initial screen layouts
Better error handling – AI suggested edge cases I hadn’t considered
Cleaner code – Cursor’s suggestions improved code organization

Some challenges:

Managing audio playback across platforms
Implementing secure content unlocking
Handling offline/online data sync

Results

The app is now live on all major platforms. Group members are using it to work through the program at their own pace, with the flexibility to read or listen to content anywhere.

What’s Next

Planned updates include:

Improved offline support
Better progress tracking visualizations
Group discussion features

For Developers

If you’re building a content-based app, consider:

Flutter if you need multiple platforms
AI tools for faster development (but review all generated code)
Markdown for content that needs frequent updates

Try It Out

The Solid Man® app is available on iOS, Android, Mac, and Windows. Download it to see the introduction content. Group members can unlock full access with their code.
