Over the past few years I’ve been a user of iOS app Voxer. CEO Tom Katis is a friend of mine, and I’ve had a great time using the app through it’s successive generations and revisions. Lately, Voxer has been accelerating in its reach, and is now hitting the prime time, moving up the Apple App Store top 10 lists, and gaining a widespread global userbase.

From Voxer’s website:

“Voxer is a Walkie Talkie application for smartphones. Voxer lets you send instant audio, text and photo messages to your friends (one or more!). Messages stream live as you talk and your friends join you live or listen later.

Voxer is available for iPhone, iPod touch, iPad and Android devices.”

Recently, CNN did a feature on Voxer, going over the product’s usage and business model.

I’ll be looking forward to using Voxer going forward, and to new versions of the app. Right now I think the actual conversation flow works well, but there’s a bit to be desired for the user list and friend discovery process.
