Nice application! I've been testing it for some hours and I found 2 bugs. Firstly, it doesn't start after rebooting, also stated by other users. It also doesn't support Greek characters (UTF8 encoding maybe?).

This is what I did. I edited the private number phrase to a greek phrase ("Άγνωστος καλεί" in case you want to test ). It works until you close the app. then the Greek letters are changed to question marks and it refuses to read it

The problem must be the config file. I think if you change the encoding to UTF-8 it will be fine, but I'm a little bored right now
