Since OICUR12 posted about the usefulness of Skype, an app and program that I love and use all the time when I’m overseas, I thought I’d share about an app for smartphones that I just discovered the other day through a friend of mine.
I find when I’m overseas and in port that I like to text friends and family back home rather than call. Conversations can take place over hours and it doesn’t cost nearly what a phone call would - although at .50/message (for AT&T at least), it does add up pretty quickly. But [WhatsApp](http://www.whatsapp.com/) seems to have solved that problem. You simply download the app on your phone (iPhone, Blackberry, Android), and ask the people you text to download it as well. For the iPhone it cost .99, I imagine it’s a similar price for the other phones. Then use the app to text back and forth, and the only cost is for the data usage.
Certainly a lot cheaper than $.50 a message! Anybody else out there use this?
