WhatsApp, the extremely popular multi-platform messaging app, has just announced the addition of voice messaging to the service. According to the WhatsApp blog:

We are releasing Voice Messages on all of our platforms simultaneously. We worked very hard to make sure that iPhone and Android devices have perfectly working Voice Messages functionality, and we put extra effort into making sure that BlackBerry, Nokia and Windows Phone users can enjoy the same rich and powerful Voice Messaging experience.

Extra effort? Is there something about BlackBerry or Windows Phone that made "rich and powerful" more challenging on their platforms?

Anyway, it's not voice calling like Skype or the upcoming iOS 7 FaceTime Audio, where you can talk back and forth to someone on the other end of a VoIP connection. It's just a way to record short snippets of audio and send them like an MMS. You can find instructions on how to do it on the WhatsApp FAQ.

If you're using WhatsApp and you try out the new voice messages, let me know how they work for you. If not, and you want to give it a try, grab it from the App Store now.
