What is the best way to find bus routes in greater seattle?

I just moved to Tacoma, Washington and need to use public transportation to get around. What is the best website or free iPhone app I could use to map trips into Seattle and stuff? ThanksWhat is the best way to find bus routes in greater seattle?
Going to Seattle, you're going to be taking the Sounder (unless you want that trip to be at least 2 hrs).

If your destination is in Pioneer Square or anywhere downtown south of say...Madison and west of 3th ave, you can probably hoof it from there (east of 3rd and you're walking up some pretty brutal hills).



For the most part, buses downtown run north and south (they're also free downtown, for now anyway). The train will let you off in the king street station and there are probably a dozen or so buses that you can take through the tunnel system to just about every central location downtown. (pioneer square, business district, westlake, etc)
