updated review -
The latest version on iOS 9.3 broke all my groups in bookmarks. The groups can no longer be collapsed and expanded, so you have to scroll through your list (my list is fairly long as I have several transfers & alt routes I track). This makes groups pretty much worthless.
They still need to fix the unreadable white-on-gray bus info section, which breaks the rules for accessibility. I sent this feedback many versions back but it still has not been fixed.
Still like the app, but taking away 2 stars for reduced usability/accessibility .

Ive used this all around Seattle, Redmond and Bellevue to find Metro and Sound Transit bus times. Ive used it to find out if a bus is running late and to find alternate busses when Ive missed a bus. One of my most-used apps.
