# What You Can Build

> From simple tools to complex apps—if you can describe it, you can build it in Bloom.

Bloom can power almost anything you can imagine, from quick personal tools to full production apps shared with thousands of users. Every app you build works on iOS, Android, and the web, so you can go mobile-first, web-first, or both. The combination of Expo's cross-platform framework and Convex's real-time backend means there are virtually no limits to what you can create.

## How to choose what to build

<Steps>
  <Step title="Start with a problem" icon="lightbulb">
    The best apps solve real problems. Think about:

    * What frustrates you in daily life?
    * What do you wish existed?
    * What manual process could be automated?
    * What information is hard to access or organize?
  </Step>

  <Step title="Define your core feature" icon="bullseye">
    Every app needs one main thing it does well. Ask:

    * What's the single most important action users will take?
    * Can you describe the app in one sentence?
    * What makes this different from existing solutions?
  </Step>

  <Step title="Keep it simple at first" icon="seedling">
    Start with the minimum viable version:

    * Focus on 1-3 core features
    * Don't worry about "nice to haves" yet
    * Get something working that you can test
    * Add complexity based on feedback
  </Step>

  <Step title="Describe it to Bloom" icon="message">
    Once you know what you want, prompt Bloom:

    <Tip>
      **Good prompt example:**

      "Build a habit tracker where users can add daily habits, mark them complete, and see their streak count. Include a calendar view showing completed days."
    </Tip>
  </Step>
</Steps>
