Trottr
Trottr allows you to send audio messages to anybody around the world, by making a simple phone call!
Whenever you feel like it, you can let your friends, family and colleagues listen in on your life. All you have to do is register your telephone on trottr. Then start recording your audio messages and making them available to others via the trottr website. Of course you can also transfer your message to your twitter Timeline. Or send it directly via email, or post it on one of your communities.

Traffic rankings are sourced from multiple sources, if available, for the Twitter application. This includes Alexa, and Compete rankings.
