Only works if app gets permission to contacts

Im glad this did not cost a dime and was free. This doesnt do what they claim. I tested it out and it didnt change the number on the receiving end as the one I typed in. So I rate it -3stars for false advertising not a one star that they force you to put just to leave a review.

Update
Finally worked but the number that you want to show up on the persons id that your calling must be already in your contacts. And you must give this app permissions to access you contacts for it to work also. This is limited and you should beable to type in any number for it to work. So now I will rate it at least 2 stars till I can type in any number instead of any from my contact list.
