(Strategic Takeaway) {#so-what} Dictionary of Collocations is a reference app that is free with in-app purchases. It holds a 3.33/5 rating from 3 reviews. > **Bottom Line:** Dictionary of Collocations must pivot toward active learning features to survive the shift toward AI-driven conversation tools, as its current static reference model is losing ground to rivals with gamified retention loops. **Best for:** English language learners seeking to improve natural-sounding speech and writing through structured vocabulary practice. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship gamified quiz module because competitors like Atasözleri ve Deyimler Sözlüğü use it to drive retention → increase daily active usage ### Feature Gaps vs Competitors - Gamified Q&A exercises (available in Atasözleri ve Deyimler Sözlüğü but missing here) ### Outlook: Declining The reference market is consolidating around apps that offer active, AI-assisted learning rather than static databases.
