Great app, one of the best for SMS/MMS messages! It's a bit awkward to have only some contacts listed to add to block/allow listed from the phone book, though, and then having to manually enter each one of those not listed in the very short and limited list manually. Also would like to see all messages synced with Google Messages app. Also miss the option to edit already blocked contacts/numbers/etc.

It's not bad, but there's room for improvement that hasn't been addressed for a while now. At the very least, this app should perform all functions of the preinstalled messaging app on my Samsung phone. The issue I dislike most is that there is no way to mute notifications from group messages, but the option is there for individual messages. The only solution is to stop using this app and start receiving spam again, or mute every notification sound on my phone..

Excellent app. I was getting lots of spam SMS and am now totally free from the annoyances. Though it perhaps lacks some of the customization features of more robust SMS apps, with Key you can block almost everything but the kitchen sink! LOL! If I had to pick one upgrade it would be a text-size setting so that old geezers like me can see things a bit better.
