App Active User

An active user is someone who engages with your app meaningfully within a specific time period. Rather than simply counting installations, active user metrics measure actual engagement with your application. These metrics provide critical insights into an app’s popularity, growth trajectory, and overall user engagement levels.

Primary Active User Metrics

Daily Active Users (DAU)

• Definition: The number of unique users who perform a meaningful action in your app during a 24-hour period
• Formula: Count of unique users who open the app and perform qualifying actions in a day
• Significance: Indicates app stickiness and daily engagement patterns
• Benchmark Ranges (2024):
  • Social Media: 15-25% of total user base
  • Gaming: 10-20% of total user base
  • Utility Apps: 5-15% of total user base

Weekly Active Users (WAU)

• Definition: The number of unique users who engage with your app at least once during a 7-day period
• Formula: Count of unique users who open the app and perform qualifying actions in a week
• Significance: Shows medium-term engagement trends and weekly usage patterns
• Typical Reporting: Rolling 7-day window or fixed calendar weeks

Monthly Active Users (MAU)

• Definition: The number of unique users who engage with your app at least once during a 30-day period
• Formula: Count of unique users who open the app and perform qualifying actions in a month
• Significance: Indicates the overall size of the engaged user base
• Industry Standard: Often the primary metric reported by major platforms and in investor relations

Derived Engagement Metrics

Stickiness Ratio (DAU/MAU)

• Definition: The ratio of daily active users to monthly active users
• Formula: DAU ÷ MAU × 100%
• Interpretation: Higher percentages indicate users return more frequently
• Benchmark Ranges:
  • Exceptional: >50% (users engage every other day on average)
  • Strong: 20-50%
  • Average: 10-20%
  • Concerning: <10%

Retention Rate

• Definition: Percentage of users who return to the app after their first visit within a specific timeframe
• Common Measurement Points: Day 1, Day 7, Day 30, Day 90
• Formula: (Users active on day N ÷ Users who installed on day 0) × 100%
• Industry Averages (2024):
  • Day 1 Retention: 25-40%
  • Day 7 Retention: 10-15%
  • Day 30 Retention: 4-8%

Active User Growth Rate

• Definition: Percentage increase in active users over a specific period
• Formula: [(Current period active users – Previous period active users) ÷ Previous period active users] × 100%
• Healthy Growth Indicators:
  • Mobile Games: 5-15% monthly growth
  • Utility Apps: 3-10% monthly growth
  • Established Apps: 1-5% consistent monthly growth
