Anyone who is tired of ordinary key-typing might find iVoiceNote useful
It might also be helpful specifically for people with difficulties in typing. Such difficulties could be of a result of physical condition, or simply not mastering the keyboard typing technique in an early enough age.
In addition, people who type a lot as their profession or hobby might find iVoiceNote very useful as long keyboard typing might be very tyring, and even have medical implications as side effects. Needless to say, transcribers (from students to professionals) will find iVoiceNote super helpful, as they can listen to a recording and repeat the speech into the mic, to get iVoiceNote to transcribe it for them.
