It really depends on where you are in Sweden. Different regions have different public transport providers.

Never thought I would defend Västtrafik(public transport in south west Sweden) but here I go.

Their webpage http://www.vasttrafik.se/ is quite usable. It finds good routes and you can fiddle around with different parameters such as times for changes etc. You can say that you are willing to walk or take a bike part of the way as well. Overall pretty good as long as you are on a computer.

On a phone the default app is not so good. Instead use ResOplanerare which has a very minimal and slick interface.
