Open Whisper Systems has released version 2 of its Signal secure calling app for iPhone. This is an important iteration, as it introduces secure text messaging that’s compatible with the outfit’s TextSecure app for Android — for now, Open Whisper Systems’ secure voice app for Android, RedPhone, remains separate from that, though everything will come together later this year in a Signal app that works across iOS, Android and the desktop. As secure communications operations go, Open Whisper Systems has good credibility, offering end-to-end crypto, auditable open-source code and decent identity verification. The TextSecure protocol has also found its way into WhatsApp, which is why Android-toting users of that Facebook-owned messaging app enjoy extra security these days.
Tinder is working on building itself an ad unit, according to Re/Code sources. The dating company contacted both Facebook and Twitter to discuss a potential advertising partnership. There’s no more information on what these advertising units could look like, but Re/Code speculated that local bars or restaurants might want to market themselves as date spots in the app. Tinder wouldn’t comment on Re/Code’s story.
