Public transportation app Swiftly launches out of beta in San Francisco today with the aim to do for public transportation what Waze did for Google Maps – save us from commuter hell. Swiftly has been in beta but called itself Swyft. The app so far has gathered 45,000 users, according to the startup, but was a mere add-on to public transit app Nextbus. Swyft is rebranding itself as Swiftly today and is now more of a competitor to Nextbus. Here's a demo of how the app works.
