And then you're done; that's it. RedPhone doesn't ask for passwords, logins, or even for users to create an account. The app is designed with privacy in mind, so it requires as little from you as it can.

In Redphone you'll find all your contacts, recent calls, a recently added dial pad, and favorite contacts. The stripped-down UI is likely by design, as one of the perks of RedPhone is that it seamlessly integrates into the Android dialer. If the person you're calling has RedPhone installed, then a dialog prompt will give you the option to make a secure call, or continue with an unsecure call.

Or, choose someone to call from the Contacts panel of RedPhone, which only displays other RedPhone users. If you receive a call from an insecure line while making an encrypted call, the new caller will be dumped to voice mail but you'll receive no alerts.

For added security, both the caller and receiver will see the same random two-word passphrase. If you're concerned that someone is impersonating the person on the other line, you can speak the first word and have them speak the second. If a Wi-Fi network is unavailable, the call will use your wireless data and not your talk minutes. The downside of this nearly invisible approach is that you can't add contacts directly from RedPhone. The app could also use a good polish, as some elements don't always look clean or finished.

For example, I could not for the life of me, figure out how to add contacts to my favorites list. The recent calls section of RedPhone is likewise confusing. RedPhone in Action I wanted to keep in touch with my partner without risking someone listening in on my calls while attending the Black Hat conference.

I occasionally had a hard time getting calls to connect, and had a few calls drop after connection was established. Sometimes, it sounded like my partner's voice was sped up and compressed, as if to make up for lag time. But most of the time, phone calls sounded great with little or no latency. Back in the PC Labs, simple tests showed an average latency of 0.

That's slower than a standard cell phone call, but most of the time I didn't notice. Ghacks is a technology news blog that was founded in by Martin Brinkmann.
