🧮 Innovative Ranking Algorithm

The core innovation of Search Apps is its review-based popularity ranking:

How It Works:

1. Review Count Analysis: Tracks total review counts across all versions
2. Weighted Scoring: Recent reviews weighted more heavily
3. Velocity Calculation: Measures rate of review growth
4. Cross-Reference: Compares against category peers
5. Normalization: Accounts for app age and category norms
6. Popularity Score: Generates a unified popularity metric

This approach provides a more accurate picture of actual app usage than download estimates or simple top chart positions, which can be influenced by short-term marketing campaigns.
