This productivity/GTD app is very well worth the money. I use it as my voice recorder when I am moving or dont want to type longer notes on my iPhone. At home I can easily transcribe the recordings into OmniFocus right from the Dropbox folder.
I also like the "quick reminder" feature which will display a push notification in e.g. 15 minutes to play back your voice memo.
Once the following features will be implemented it will replace my current voice recorder app of choice (DropVox):
• enable a beep at the beginning/end of a recording
• lift the recording limit of 10 seconds
• edit the file name format (or use the ISO 8601 standard YYYY-MM-DD HH-MM-SS)
