Truth Layer
DirectionalLeadingAI-Sensitive Truth Layer
The Truth Layer is the badge system that tells you how trustworthy, directional, or risky a measure is.
Why it matters: It helps teams separate meaningful signals from vanity, misuse, or AI distortion before they optimize the wrong thing.
Example: A metric can be Meaningful, Leading, or Vanity Risk.
DAU/WAU Ratio
The ratio of daily active users to weekly active users, indicating how many days per week the average user returns.

What it is best for
Understanding how embedded the product is in users’ workflows
What it tells you +
How frequently users come back. A high ratio means the product is part of users’ daily workflow.
What it does not tell you +
Tell you about depth of engagement or whether daily visits are meaningful.
When to use it +
- Understanding how embedded the product is in users’ workflows
- Comparing engagement trends over time
When not to use it +
- For products with naturally low-frequency use patterns
- Without normalizing for product type expectations
How leaders misuse it +
- Treating any ratio below 0.5 as bad without considering product category
- Ignoring that notifications can artificially inflate daily active counts
Anti-patterns +
- Sending excessive notifications or emails to inflate daily engagement
AI interpretation risks +
Scenario: AI sends daily digest or personalized summaries
What happens: DAU increases as users open AI-generated summaries
What it really means: Users may be clicking notifications, not engaging with the product. Engagement may reflect AI-driven prompting, not organic value.
Recommendation: Track session depth alongside DAU. If sessions triggered by AI notifications are shorter, the engagement is shallow.
Companion entries +
This entry is stronger when paired with:
Instrumentation or evaluation guidance +
Define "active" consistently — a page view, a logged action, or a session of minimum duration.
Sample events
session_start, active_action Examples +
A project management tool has a DAU/WAU of 0.71. After introducing AI daily standups, the ratio rises to 0.82 — but average session duration drops from 8 minutes to 2 minutes.
Suggested decisions +
- Ratio above 0.6: strong daily habit. Protect this with stability and performance.
- Ratio 0.3-0.6: moderate engagement. Investigate what drives daily visits for power users.
- Ratio below 0.2: low frequency is expected or the product lacks a daily value proposition.
