Response from developer

The destination is provided by SFMTA and sometimes specific trains terminate early at Embarcadero! Of course, that's not to say it still wasn't wrong lol

very good！

I like the app very much. It is simple very easy to use！Very straight forward！
But I found prediction for Castro Westbound and Embarcadero Westbound are the same. Please correct it.
Thank you so much for creating such amazing app！
