How to delete all the recordings from the Voice Memos app on iOS? I need to delete all the tracks from Voice Memos app in iOS, in order to free up storage on my device. Deleting tracks one at a time is not an option since I have hundreds of them.

I am using an iPod touch 4G.
Open the app and you'll find a little symbol with 3 horizontal stripes in the right bottom corner.
You'll get a list and you can tap the memo and click "delete" right afterwards.

Or in iTunes you can select all voice memo's after you've synced them to your PC and delete them from there.
