BeenVerified, the company behind the Antoine Dodson-endorsed Sex Offender Tracker app, is back with another offering that looks to disrupt the reverse directory space. The firm’s latest app, NumberGuru, provides users with free unlimited reverse phone number look-ups. The app is also tied to a social service where users can post comments about numbers they look up with NumberGuru, helping to identify phone spammers for future searchers. Available immediately for the iPhone, Android smartphones and on the Web, the app and service are completely free, and BeenVerified told us that the company plans to keep it that way. BeenVerified also told BGR that since the app was updated last week, NumberGuru is averaging about 10 look-ups per second, or 864,000 look-ups each day.
