Proof of Usefulness Score

You're In Business

Bangl is a legitimate niche product (NFC/QR safety wearables and B2B compliance tools) operated by 'www.com ltd' (est. 1996). However, the submission contains wildly exaggerated claims ('most people have used my product', audience 'everyone') that contradict reality. While the technology has verifiable B2B utility in construction and medical sectors, the project represents a small SME, not the global phenomenon described. The input quality is poor, using confusing metrics ('marketcap: 50000') and gamer-tag identifiers.
