I am wondering why I purchase this app. The free app.gave only location so I purchased the Pro version for $8.99 to access more information the results are the same nothing more I will cancel my account I am not getting what I paid for.

Developer Response ,

Hello Fitzdave87, thanks for the feedback. The reverse search in the free version shows all information available about the caller. The Pro version allows you to identify and block incoming calls. Please note, that this app only identifies unwanted calls that have been reported on tellows and no private numbers. Regards, Your tellows Team
