Mementum from AllGoritm (www.allgoritm.com) is a stylish voice reminder that lets you record vocal memos, then sort your recordings by categories. With it you can also write additional text notes.

Voice reminders — or any other sounds — can be recorded via your Mac’s mic as a new Mementum reminder. Just click the Record button.

There’s also a global hotkey. To make a new recording use Cmd+Shift+M, and Mementum will immediately start recording. Press Cmd+Shift+M and the app will save the recorded item and give you a reminder in 15 minutes by default. You can change the time period while making the reminder, if you wish.

You can use Mementum as a storage for all your reminders until you decide to erase them or to use ’em again. The entire recording list can be sorted by categories.

Mementum costs US$4.99 and requires Mac OS X 10.7 or later. It’s available at the Mac App Store (http://tinyurl.com/bm34bdf).
