Spectrum analyser with ACP or Dropbox?

[Guaranath]

I have a friend who working with only an ios device (no PC or Mac) and was curious if anyone knows of any ios spectrum analyzers that support either ACP (AudioCopyPaste) or have a Dropbox functionality? Or if some other viable option exists would love to hear about that too...

Have a look at AudioView: it can plot a spectrum, and it supports ACP.
