1) The Core App Features:

Key insight: Keep it SIMPLE. Basic features done well better than complex features done poorly.

– Start with basic wireframes
• Copy "primitives" from successful apps

• Make results instantly digestible
Pro tip: Design screens thinking about how influencers will showcase them in content.
3) Growth Strategy:
Target audience = concerned parents
Best channels:
• Mom influencers
• Family content creators
• Parenting communities
Look for creators with 250k+ views/video
Budget: $4-5k per 1M views
4)Monetization Structure:
Weekly pricing model works best:
• $4-7/week
• No free trial initially
• A/B test different prices
• Optimize for repeat users
Strategy: People will delete/resubscribe when needed
5) Technical Implementation:
– Use ChatGPT API with custom prompts
• Bypass medical disclaimers creatively
• Build clear diagnosis displays
• Include danger levels (1-5)
• Add sources for credibility
6) Marketing Angles:
– Target anxious parents
• Focus on peace of mind
• Show quick diagnosis stories
• Emphasize "should I see a doctor?" use case
• Leverage influencer storytelling
7) Key Success Factors:
• Heavy disclaimers
• Accurate diagnostics
• Simple UX
• Clear value prop
• Strong retention hooks
