Wanted to try it out but couldn't do it for free. The registration page, not accessible through the app but directly from the web, requires payment. Where's the free trial? All the Enterprise talk in their material should have been an indicator, anyways, so why am I even complaining here...?

The price to pay is sufficient to drop 2 stars from an anotherwise excellent and secure communication platform. Too expensive given that there are free apps like Signal that provide most of the features of Silent Phone as well as commercial ones, like Threema, BBMe, Wickr and Wire that do so at a fraction of the price.

Thanks Demetris for using Silent Phone. Regarding the price, we know charging money is a bit old-fashioned, but it makes it clear we work only for our customers. We offer a premium product, and the price you see helps us to ensure it remains the best in the market. Many of our features, e.g. our secure conferencing and PSTN calling are unique.

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.
