Works very well. However, like all other encryption apps, you need to convince family and friends to use it. I do appreciate the encrypted calling or use the silent phone for a second line feature. The security is worth the price.

I think Mr Zimmerman is a genius. So I used his app from the beginning. I think a 3 star rating is harsh as SC pioneered secure voip. For most part continual improvement. The move out of Switzerland to U.S. is major concern to me. Also more information around silent world be awesome. Also being able to have more than phone number maybe 3 per user. I would also like a voice changer so if recorded by the party your talking to it sounds like some one totally different. Choose female or male and choose many accents even versions of accents. Make voice deeper. Also a way to detect Sting Ray's or close in monitoring equipment. Also potentially Add a VPN and brave style browser which auto wipes all surfing data after each use. Cheers guys ... I hope you like my wish list and get a laugh to, cause I am serious.
