User Experience Considerations

Onboarding

First-time user flow:

  1. Value proposition: "Track your dreams, discover patterns, achieve lucidity"
  2. Privacy assurance: "Your dreams are private and secure"
  3. Quick tutorial: 30 seconds max
  4. Optional account creation: Let users try first
  5. First dream entry: Guided experience

Don't require extensive setup before value delivery.

Notification Strategy

Be extremely careful - dream apps can annoy users quickly.

Useful notifications:

  • Morning reminder to record dreams (customizable time)
  • Reality check reminders (if lucid dreaming features enabled)
  • Weekly dream summary
  • Achievement unlocks

Never:

  • Push for engagement daily
  • Interrupt during likely sleep hours
  • Spam with features user hasn't enabled

Default: Minimal notifications, user can opt-in to more.

Performance Optimization

Speed is critical for morning dream recording:

App launch: Under 2 seconds cold start
Voice recording: Instant start
Dream save: Immediate (sync later)
Search: Sub-second results
Symbol interpretation: Instant if cached

Technical approaches:

  • Local-first architecture
  • Aggressive caching
  • Background sync
  • Lazy loading for analytics
  • Optimistic UI updates

Accessibility

Make dreams accessible to all:

Voice input: Essential for vision impairment
Screen reader support: All features navigable
Large text support: Readable in morning grogginess
Dark mode: Reduce eye strain when recording at night
Color contrast: WCAG AA minimum
Haptic feedback: Confirm actions

Technical Architecture

  personalMeaning?: string; // User's interpretation
  occurrences: number; // How often it appears
}

interface Interpretation {
  symbols: SymbolInterpretation[];
  overallThemes: string[];
  generatedAt: Date;
  source: 'api' | 'user' | 'ai';
}

Storage Strategy

Mobile (iOS/Android):

Local database: SQLite or Realm

  • Fast queries
  • Offline-first

API Integration

Dream interpretation API integration:

// Initialize SDK or direct HTTP calls
class DreamInterpretationService {
  private apiKey: string;
  private baseUrl = 'https://roxyapi.com/api/v2/dreams';
  
  async searchSymbols(query: string) {
    const response = await fetch(
      `${this.baseUrl}/symbols?search=${encodeURIComponent(query)}`,
      {
        headers: {
          'X-API-Key': this.apiKey,
          'Content-Type': 'application/json'
        }
      }
    );
    return response.json();
  }
  
  async getSymbolById(id: string) {
    const response = await fetch(
      `${this.baseUrl}/symbols/${id}`,
      {
        headers: { 'X-API-Key': this.apiKey }
      }
    );
    return response.json();
  }
  
  async getRandomSymbols(count: number = 1) {
    const response = await fetch(
      `${this.baseUrl}/symbols/random?count=${count}`,
      {
        headers: { 'X-API-Key': this.apiKey }
      }
    );
    return response.json();
  }
}

Caching strategy:

  • Cache symbol interpretations locally
  • Refresh weekly
  • Offline fallback
  • Reduce API costs

NLP for Symbol Detection

Extract symbols from dream text:

// Simple keyword matching
const detectSymbols = async (dreamText: string) => {
  const words = dreamText.toLowerCase().split(/\s+/);
  const symbols = [];
  
  for (const word of words) {
    // Check against symbol database
    const matches = await searchSymbols(word);
    if (matches.symbols.length > 0) {
      symbols.push(...matches.symbols);
    }
  }
  
  return deduplicateSymbols(symbols);
};

// Advanced: Use NLP library
import nlp from 'compromise';

const extractSymbols = (dreamText: string) => {
  const doc = nlp(dreamText);
  
  // Extract nouns (potential symbols)
  const nouns = doc.nouns().out('array');
  
  // Extract verbs (actions in dreams)
  const verbs = doc.verbs().out('array');
  
  // Extract places
  const places = doc.places().out('array');
  
  // Extract people
  const people = doc.people().out('array');
  
  return { nouns, verbs, places, people };
};
