Priority ranking from 1 to 10 shades the audio page from green to red.

Another recorder app that focuses on organization, Voice Memo Recorder lets you create your own categories for audio notes. As a clever twist, you can rank recordings with a priority rating of 1 to 10, and they're labeled in shades from green to red according to the priority number. You can also sort recordings according to category, priority, date, and title, a scheme that other App Store hopefuls would do well to mimic.

While those features show promise, Voice Memo only has one audio quality setting, a lowly 8 kHz AIFF (CD quality is 44.1 kHz). That keeps files small, which is a virtue for some, but it renders Voice Memo poor for podcasting or field recording by sound designers or musicians. Voice Memo does however, allow you to email recordings as a way of offloading them.

While the app was reasonable to figure out, some instructions would have helped at times. However, Concrete provides no in-app or online documentation, which is rare, not to mention annoying. When you factor in semi-regular crashes, including while recording, Voice Memo disappoints.
