The grand daddy of audio apps, nanoloop, originated on the Nintendo Gameboy but it is still seeing updates on iOS! This update adds new file management and sharing options.

What's new:

• Send and receive .nan as email attachments
  The "send" function now sends .nan files as actual attachments. Files can be handled like any other attachment, they can be saved on a PC and also be opened in the Android version and vice versa. This feature is only available on iOS 3.2 or higher. On older versions, you can still send files URL-encoded.
• Open .nan files anywhere
  Nanoloop is added to the "open in" dialog. When you open a .nan file in Safari, Mail, Dropbox or any other app that can present an "open in" dialog, nanoloop starts and imports the file.
• Share .nan files with Dropbox and others
  If file sharing apps like Dropbox are installed, there is a "share" function that allows to open .nan files in compatible apps.
• Share WAV Exports
  If compatible apps are installed, an "open in" menu will appear after WAV export, allowing to open the exported file in any app that can open WAV files.
