<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [PIVOT] Audit ad frequency during active test sessions because users report interruptions every thirty seconds → reduce churn
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Declining

The casual brain-training market is consolidating around apps that offer higher content quality and less intrusive monetization. IQ Test Brain Training Riddles is currently exposed due to its reliance on aggressive ads and unpolished content, which will continue to depress its Android rating and organic growth.

- 🔴 Aggressive ad frequency during testing sessions disrupts the user experience, which directly correlates with the negative sentiment trend in recent reviews.
- 🔴 The lack of feature expansion over the last quarter, combined with maintenance-only updates, leaves the app vulnerable to rivals with more frequent content drops.
