VoiceThread is a nifty free iPad/iPhone app for users of VoiceThread. A user can pretty much do the same thing they can do on the site such as uploading photos, adding comments, adding audio, and then drawing over a picture. When the digital story is done it can then be shared via an email. Also, this is a great way to manage and view VoiceThreads on a mobile device.
I highly recommend checking out the VoiceThread app by clicking here!!
