Audio Memos Pro
Audio Memos pro is a professionally designed audio recorder that can be used to record sessions, interviews, home practice, and group therapy. This app is easy to use, and recordings can be compressed and sent as files, which makes storing speech samples easy and efficient. Some limitations of this app are that the recording quality is best with the addition of an external microphone, and it is not capable of recording video.
