The app DOES NOT contain any sort of database of names or addresses, it merely searches the internet to find its results.
Like any other reverse lookup this app has some limitations. This app will find some registered owner of a cell phone number approx 50%-70% of the time depending on the number, location, and carrier of the number that you are trying to search.
WORKS ONLY FOR PHONE NUMBERS IN THE UNITED STATES
THE APP WORKS ON MOST ANDROID MODELS WITH ANDROID VERSION 4.1.x (Jelly Bean API 16) and HIGHER (I have not tested all models)
