A simple but effective app that tells me what I need to know. Navigation is pretty intuitive—there's not a lot to it, but sometimes, less is more. I like that it's uncluttered, which, these days, is a definite plus. One feature I can't get to work, tho, is "Lookup any number." When I attempt to use it, the app crashes. Sure wish it worked as described—or at least, wouldn't crash the app...

Update: I deleted this app because it kept crashing and wanted too many permissions. Even after I gave it all the permissions, it still kept showing a pop-up telling me to grant permissions. Too bad, because it was starting to get better at identifying callers. So. I haven't found a decent replacement app yet. I have my phone set to do not disturb permanently. If a caller is not in my contact list, it won't ring. Oh well.

It does a good job of detecting calls, not perfect but plenty good enough. An update: the feature which allows you to block area codes does not work. I've tried un installing and reinstalling but still doesn't work. I've looked over other call-blocking apps and they seem no better. This one's free with NO ads. I'll stick with it and its imperfections.
