Twitwoop is a simple Twitter tool that allows you to send a voicemail to your Twitter account. Who’s the voicemail for? Why your Twitter followers of course, or you if you need to give yourself a friendly reminder of something while on the go. Using your phone, you can dial-in to one of the service’s worldwide landline numbers and leave a voice message. The service supports numerous cities in the U.S. and several across Europe. Simply log-in using OAuth for your Twitter account, enter the phone number that you’ll be calling from and you’re all set to voice record.
Twitwoop keeps a record of your past recordings for easy accessibility and supports replies of direct recordings back to the author.
