First of all, a very big thanks to our inaugural guest segment host, Dana Brunetti! In addition to being an awesome guy, Dana is the producer of House of Cards, Fifty Shades of Grey, and the Social Network (and is apparently a commandN.tv fan from back in the day - how cool is that?).
Dana's app pick is Voxer, a cross-platform mobile messaging app for teams that he's used for work. At its core Voxer allows for a push-to-talk walkie-talkie experience between two or more users, but it also keeps messages for you in case you miss them or want to review them again, and it lets you send text and photos as well.
Voxer is available for Android, iOS, Windows Phone 8, and desktop (browser and Windows versions).
