When fetching Play Store reviews, SENTIFY uses stratified sampling by fetching reviews across all 5 star ratings (1-5 stars) instead of just the newest reviews. This ensures:
- Balanced representation of negative, neutral, and positive reviews
- More accurate overall sentiment analysis
- True reflection of the app's actual sentiment distribution
- Helps app teams monitor user satisfaction continuously from real reviews.
- Detects post-release problems early (for example, crash complaints or UI friction) before ratings drop.
- Highlights what users love (such as easy UI or fast performance) to guide product, roadmap, and marketing decisions.
- Supports growth by improving review quality insights, protecting ratings, and helping teams prioritize high-impact fixes.
- Aligns with industry-standard review intelligence workflows used by tools like Appbot, Apptweak, and Sensor Tower.
