Twodio

With Twodio, You can post audio tweets to your audience in THREE simple steps:

• Click To Record
• Speak Your Tweet
• Post On Your Twitter

According to me, why I think this applications is cool:

• Minimal Design, easy to setup and function.
• Interact with your audience easily without typing out a tweet and restrict yourself with 140 characters.
• It plays audio tweets inside the Twitter Page rather than taking the user away from the website.
• Perfect for Social Media Influencers and Celebrities to interact with their fans and send them short audio messages.
• This app can be used to create Short Podcasts, Audio Vines, Radio Shows and Several other Sound pieces.

Note: You need to connect your twitter account to use this application.
