I saw this app one day and checked it out and I've had it ever since. It has protected me from a Amazon scam (fake Amazon). The guy was trying to get in my ph and duck duck go would not let him. And the scammer wanted me to go down the street to CVS and use their internet. Well, I didn't go and he tried to call me back. I blocked him and reported it to the real Amazon. So I recommend Duck Duck Go!
