Been using this app for years. Does great with blocking spam texts (best feature: you can block based on word content, eg "Trump", "Biden", "election", etc). But the app is buggy and often crashes. It's also slow, and sometimes fails to download a text, which can be very annoying. I wish the app didn't run so poorly.

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.

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.
