This app works as described by the developer. Now I am not getting disturbed by any spam call. Thanks for a great app. I highly recommend to download.

★★★★

It would be 5 stars if only the call recordings weren't so terribly hard to sort. They are in day-month-year format, so every 1st is together, which is not at all handy when you're looking for "a call that happened in January". It also needs to have an obvious way to pause the damn thing, uninstalling it to make confidential calls that require the keypad, and then reinstalling it, is cumbersome. Edit this does nor appear to record calls anymore, which makes it less than useful.

Suddenly all of my audio disappeared. No way to figure out where mp3 files are stored. If it worked, I might pay for it. Very disappointed as I needed some of those recordings.

First, I can't get recording to work. I then went to their website to contact them with my question. When you click Submit you only get "An error occurred while sending the message. Please try again later." So it seems the only thing I can do is leave this review and try another app
