Co-Founder of Embark here (letsembark.com). We have apps for 12 systems, mostly in the US (BART, Caltrain, NYC, LIRR, MNR, NJT, DC Metro, Philly, CTA, Metra, Boston & London Tube). We also integrate with iOS 6 maps, so our apps should show up for you if they're relevant. In my subjective opinion, it's a way better experience than a google maps web view.
EDIT: Looks like my co-founder David beat me to the punch
Currently we don't have an app for muni, though it's something we're working towards. There are some nice apps for Muni that have real-time arrivals but lack routing. Transporter & Routsey are probably the two best.
Not sure if Google is monitoring your posts or if their routing glitched before but doing the search just now gave me pretty much the same results on Google Maps... http://goo.gl/maps/fsfKF
Having had the beta for so long I hadn't actually expected integration with maps, I figured it'd just tell you that there were other apps available. I'll definitely be moving to embark for the time being!
