VoiceMarker is a simple voice recorder app that lets you mark different points in the recording with simple notes for easy reference in the future. This app is great for students to record lectures or for people who are in a lot of meetings and seminars. It lets the user type in custom notes for future reference. Also in order to minimize the interaction with the phone while the recording is going on, the app provides shortcuts for built-in marks in the notification center. The user can create marks at different points in the recoding and go back to each specific mark without having the listen to the entire recoding later on.

Verdict

The call

VoiceMarker's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 17.0). On price and ads there is nothing between them.
