It's free, but you get what you pay for. – Dictaphone Voice Recorder Review

It get the job done eventually, but it seems like the developer never actually used their own app. The good: 1) It's free. 2) Once recording starts, it seems to do a good job. 3) The voice activation works well (for me). 4) Deleted recordings go into a temporary delete location (so you can recover them if you accidentally delete them) and can then be permanently deleted later. The not so good: 1) You can make setting adjustments ONLY while a recording is in session. As soon as you open a new session, it starts recording immediately, so you have to start a new recording, choose your settings, stop the recording, click back to the summary page and delete the recording, then start all over with the recording you wanted in the first place. 2) With all the deleted recordings you end up with, you will need to visit the permanent delete option often. Good luck. The developer decided the only way to access this is to shake the phone. If it work most of the time, it might be acceptable, but you'll end up spending more time shaking the phone trying to delete the recordings than you did making them in the first place.
