The Power User Curve: The Best Way to Understand Your Most Engaged Users
DAU/MAU hides the distribution of engagement across your users. The Power User Curve reveals whether you have power users at all, what business model fits your engagement pattern, and if your product is actually getting stickier over time.

TLDR
• Plot a histogram of how many days per month users are active (1-30 days) - the shape tells you everything DAU/MAU obscures
• A "smile" curve (users clustered at both low and high frequency) indicates power users and supports ad monetization; left-weighted curves need transaction-based revenue
• Track cohorts over time to see if users are shifting right (more daily usage) - this shows if product changes are working
• Customize the metric: use 7-day windows for B2B/productivity tools, measure core actions (posts, purchases) not just logins
• Different product categories have different healthy curves - LinkedIn's left-weighted curve is fine because it monetizes infrequent high-value actions
In Detail
The Power User Curve (also called L30 or activity histogram) plots users by how many days per month they're active, creating a distribution from 1 to 30 days. Unlike DAU/MAU's single number, this reveals the variance in your user base: whether you have power users, casual users, or mostly one-time visitors. A "smile" shape - with users clustered at both low frequency and high frequency (daily usage) - indicates a healthy social product with power users who can support ad monetization. Facebook's curve would show 60%+ of MAUs on the right side, using it daily.
Left-weighted curves without a smile aren't necessarily broken - they just require different business models. Professional tools like LinkedIn or Wealthfront have users who engage 1-2 days per month, but monetize through high-value transactions rather than ad impressions. The key insight is matching your curve to your revenue model. You can also plot 7-day versions (L7) for B2B products that follow weekly cycles, or measure core actions (posts, purchases) instead of just logins to see engagement with what actually drives value.
The real power comes from tracking cohorts over time. If successive monthly cohorts show users shifting right toward daily usage, your product is getting stickier - network effects are kicking in or a feature launch worked. This lets you diagnose what's working and double down. For marketplace products, you can segment by geography to see which markets have achieved density. The framework forces you to think about what engagement pattern your product category naturally has, what that means for monetization, and whether you're improving the right metrics for your specific business.
