Useful, constant arrival time updates
First, accept the fact that Muni bus arrival times are mostly a mystery and never totally on time. Swiftly cant be blamed for that. That said, I appreciate Swiftly constantly updating the times and showing me where the bus is on the map. The menu and navigation are a little complicated; would like a quick option just to view my favorite routes. Its probably in there somewhere but I find it hard to access. Still, for commuters, this app is better than Google Maps.
