Bandcamp now has it's own iphone and android app
As ever, Bandcamp get it pretty much spot on:-
- generally seems easy to use and it all works properly
- the app itself is less than 1MB.
- it seems to be perfectly happy streaming albums over 3G. It worked fine when I was sat at my desk at work. Was even more impressed to find I could walk into town to get my lunch and go in and out of shops etc without a single glitch.
- it's really good on privacy as it only asks for network access instead of full access to everything on the phone like some apps do.
