Ratings and Reviews
Great app and outstanding service!
Even though I’m a fairly new customer, I have found incredible value in the service it offers. While there are many apps that offer, and likely do, provide secure encrypted communications, I haven’t found another with the phone features.
I think that many of the other apps operate under a premise that both users will have the app. But what happens when both users don’t? This is where Silent Phone offers a unique feature: a VOIP number with security built in.
I serve in the military and occasionally travel to locations outside of the US. With Silent Circle and Silent Phone as long as I have WiFi connectivity I always have one phone number to call out and receive calls. This simple feature itself is is worth every penny. The ability to call anyone, whether they’re in the Silent Circle community or not, is probably the single greatest feature for me.
Thank you, Silent Circle!

UPDATE: We removed the audio underflow tone and replaced with a visual indicator. In the next release of Silent Phone 6.1 (coming soon) you will no longer hear this tone. Again, if you are in a poor network environment you may have some delayed audio and see the Network Trouble indicator on your screen. We hope this helps your experience a bit.
Hi Oceanlite. I'm sorry that you are hearing the audio underflow tone. Its there to alert you that the connection is poor. But what you describe sounds like this is a constant occurrence. If you are connecting via wi-fi, its possible that the network isn't viable enough for VoIP traffic. I'd be happy to connect with you to trouble shoot. Thank you for taking the time to write a review. I hope we can resolve this to your satisfaction. ps we are working on a visual indicator to replace the underflow tone. Perhaps this will be a better experience for you. UPDATE: some good news. We will be working towards a solution that will allow you to control that tone. Your feedback along with others on this issue has been an integral part of our changes for future development. With that, I'd like to say "thanks" and add a few credits to your account on us. PS, let me know how things are going with the new beta.
Latest update is causing app to crash
Hi SC Dev team,
I’ve been using the app for 4.5yrs on an iPhone 5S. The most recent updates made is causing intermittent crashes when the app tries to connect to your server (red-blue- to green).
