Visualization Types Used

  • Bar charts for direct app comparisons
  • Heatmaps for behavioral patterns across time
  • Donut charts for usage distribution
  • Scatter plots with regression for correlation analysis

Data Analysis Approach

Different chart types were selected based on analytical goals:

User Count
Measures App Reach
Total Time
Measures Attention
Avg Time
Measures Engagement

Chart selection rationale: Bar charts compare apps directly, while heatmaps and scatter plots reveal behavioral patterns across time and categories.

App Popularity & Engagement

Top Apps by Metric

N
Netflix
Largest user base
Gmail
Largest user base
Spotify
Top screen time
WhatsApp

Weekly Screen Time Patterns

Screen time increases toward the end of the week, with Saturday showing the highest usage.

Category Behavior by Day

🎬
Entertainment peaks weekends
πŸ’Ό
Productivity highest mid-week
πŸ‘₯
Social peaks Wednesday
πŸ”§
Utilities highest Saturday

Key insight: App usage follows real-life weekly routines β€” work during weekdays, entertainment on weekends.

Productive vs Non-Productive Usage

75.16%
Non-Productive
24.84%
Productive

Reality check: Entertainment and social apps dominate overall attention, highlighting the challenge of maintaining productive screen time.

Launches vs Screen Time Behavior

Scatter plot regression shows no strong relationship between app launches and screen time:

Statistical finding: Opening apps more often does not mean longer usage time. The relationship is statistically insignificant.

Behavioral Patterns Identified

⏱️ Long-Session Apps

Fewer launches but longer sessions per use

Notion YouTube Twitch

⚑ Quick-Check Apps

Frequent launches but short sessions

Gmail Slack TikTok

Notable pattern: Netflix shows binge-style behavior β€” long sessions with low launch frequency.

Key Insights

πŸ“± App Reach β‰  Engagement

High user count doesn't guarantee high engagement. Notion has fewer users but highest engagement per user.

πŸ“… Weekly Routines Matter

App usage follows predictable weekly patterns β€” productivity mid-week, entertainment on weekends.

⏱️ Two Usage Styles

Users exhibit either "long-session" or "quick-check" behavior depending on app type.

🎯 Entertainment Dominates

75% of screen time is non-productive, highlighting the attention economy's pull.
