Not bad

Pros
Automatically refreshes (others dont)
Pretty accurate in my experience

Cons
Like others said doesnt remember recent stops

Randomly hangs when I click on a bus to see its location on the map

If a stop has multiple buses, it will sometimes only show the route you selected, making you select another bus for the same stop (example, if you are wanting to know if the 36 or 22 will be coming sooner, you must select each stop separately)

I agree with the others, an update is long overdue!
