Do not even trial this app. I did. It doesn't get rid of all spam, maybe 25%. I unsubscribed it before the trial. Since then they keep charging me $55.99 every 3 months. I've contacted them many times but they say I'm not on their system any more but the charges keep coming. Google won't help. ANZ bank say the only alternative is the cancel my card. Yay. Be careful the guy who runs Add Tranquillity is a nasty fella. Cheers
