When doing work on location, it would be nice to have my PC loaded up with aps such as Photoshop or Audition, then take the files back to my PC for editing.
Can I do this with one subscription? Also, is there an adobe CC for the Android or iPhone?
yes, and yes.
you are allowed to installed your cc desktop app and cc programs on an unlimited number of computers. the only (minor for an internet connected computer) limitation is that you can only activate on, up to, two computers at any one time.
just install the cc desktop app on each computer, https://creative.adobe.com/products/creative-cloud
