Subscription-Based Monetization in a Coloring Book Game for Kids

1. About the Game 

This case study focuses on a Coloring Book Game for Kids, designed for early learners and preschoolers. The game provides a wide range of digital coloring pages—animals, shapes, characters, and story scenes—encouraging creativity and motor skills development.

2. The Challenge

• COPPA Compliance Restrictions: Ads were strictly prohibited due to targeting children under 13.
  
  
• High User Acquisition Costs with no ad revenue to offset
  
  
• Weak Subscription Conversion: Less than 2% of users subscribed in the first 30 days
  
  
• Lack of Progression: Children played and left without motivation to return
  
  
• Parental Skepticism towards in-app purchases
  
  

3. Strategy / Solution

• Redesigned UI to prioritize large buttons, colorful animations, and interactive feedback
  
  
• Added narrated voice-over guidance for non-readers
  
  
• Created gentle “page flip” transitions for immersion without overstimulation
  
  

Parent-Focused Value Messaging

• Added a dedicated Parent Dashboard with session tracking, art history, and progress graphs
  
  
• Displayed learning benefits (e.g., fine motor skills, shape recognition) tied to each coloring category
  
  
• Included a transparent pricing page explaining the app is ad-free and 100% safe for kids

Engagement Loops

• Introduced daily coloring challenges with badges
  
  
• Enabled “Save to Gallery” + Print option for parents
  
  
• Added narrated bedtime coloring stories to increase nighttime usage
  
  

4. Monetization Strategy

• 
  No ads or rewarded video monetization used due to children’s data protection laws
  
  
• Focus on subscription LTV and extended free trial conversion window (30 days max)
