Proof of Usefulness Score
Industry Mainstay

Readdle is a highly established industry leader in the iOS productivity space with verifiable massive traction (175M+ downloads, 300+ team). The project demonstrates exceptional real-world utility and market dominance. However, the submission quality itself was extremely poor (vague claims, missing financial data), which significantly penalized the 'Response Quality' metric. Despite the lazy submission, the external verification of the entity validates a high score in the 400-700 range, positioning it well above smaller peers.
