The People's Dictionary. I am not sure how good it is for I have not used it myself. However, I am sure it is better than nothing. And it has audio samples for Swedish words. Here is a link to it: http://folkets-lexikon.csc.kth.se/folkets/folkets.en.html#lookup&dictionary&0

Maybe not what you are looking for, but I use "Tyda" an iPhone app a lot.

Tack:)

The one I am using is Tyda.se, works jolly good!
