Proof of Usefulness Score
Industry Mainstay

PDFTron (now Apryse) is a verified industry leader in document processing technology. The project demonstrates exceptional Real-World Utility and Audience Reach, with the Xodo app achieving over 100M+ installs globally (far exceeding the 7M claim in the description). The technical implementation of a proprietary rendering engine 'from the ground up' represents high innovation compared to wrapper-based solutions. However, the submission quality itself was poor, with lazy data entry ('most people have used my product', 'marketcap: null') and a lack of specific, up-to-date business metrics. Despite the lackluster submission effort, the undeniable scale, technical dominance, and market penetration of the actual technology warrant a high score in the 'Large Scale' calibration range.
