Dragon Recorder 
just released by Nuance is a new app designed specifically to record your spoken voice for playback into either Dragon NaturallySpeaking (Windows – Premium & Professional edition only) or MacSpeech Scribe (Mac), known as deferred transcription. Perfect for those who need to record their thoughts, notes and letters when they are not sitting in front of their computer.
Obviously digital voice recorders currently play a big role in the spoken voice market and also a quick look on the iTunes app store you will find hundreds of voice recording apps. Makes total sense that Nuance want to move in to this space and control it on iOS devices. Their new app called Dragon Recorder is similar to just about every other voice recording app out there, it is fairly basic and very easy to use. One key feature that is missing in this and most other voice recording apps is an insert/overwrite feature. Insert and overwrite lets you, when reviewing your audio, insert more dictation within the audio file or remove chunks of dictation from within the audio file like sentences or paragraphs.
