I would not even give this app one star, but obviously I have to. This is by far the worst app I have ever installed. I thought it would do some good but all it does is attract spammers to call your phone so the stupid app can tell you that its a spammer. The day I installed it, within minutes I had already received a spammer. A another one called not even 5 min later, 3 minutes, 2 minutes and so on. Always unknown numbers. This repeated itself for at least 15 times in less than 2 hours. Well enough of this, I deleted it. Its funny how 4 days went by and I have not received one spam call since. I really did not get a whole lot before I installed it. Maybe one or two a week. I just thought I would try it out, worst mistake ever. I will never install another spam caller app on my phone again. I just will simply not answer like I normally do. However if a spam call becomes frequent, I will infact answer, give them a piece of my mind and tell them I dont give a crap of what they want or are trying to sell me. I am not falling for their scam and hang up. No one should have to deal with these scammers and I would hope no one falls for their trick. At the same time, this app needs to be perminently removed from the app store. I like how you can block numbers that show up, however, I dont like how you can not block unknowns. There should be a way where they can not block their number and if they try to, the call simply will not go through. Thank you.
