We don't know about you, but most of us Engadget editors live in a perpetual state of inbox insanity. Keeping on top of voicemails, text messages, emails, IMs, Twitter DMs, Facebook and Google+ messages -- to name just a few -- is a herculean yet unavoidable task. As a result, personal messages often get drowned out in a sea of work-related correspondence.
Sounder is an app that aims to ease the inbox pain a little by providing a simple and immediate way to speak with those people that matter. Pick a few important Facebook friends and the app lets you talk to them directly at the push of a button via VoIP. The goal is to keep you connected to the folks closest to you. Sounder -- which launches today for free -- supports the iPhone and iPod touch, with iPad, desktop and Android versions in the works. A $0.99 in-app upgrade enables a super slick "flip-to-talk" feature which lets you reply without waking your phone -- just turn it over and speak.
After meeting founders Nancy Broden (of Twitter fame) and Michael Fortson (former Qik Director) at SXSW, we got the chance to take an early prototype of Sounder for a spin and came away impressed with how simple yet effective it is. Since our demo in Austin, the company's been busy fine tuning the app and putting in the final touches -- like that "flip-to-talk" functionality. Want to know more? You'll find some screen shots in the gallery below and our hands-on video after the break.
