CTRL+F'd Philadelphia / Philly and no results, so:

I love this app for getting around Philly. It's spot on for planning out the best time to leave to get somewhere and I really like its UX.

I have saved so much time, hassle, and money when following its suggested routes … whereas with Google Maps or just my current knowledge of Philly transit I would have taken a worse transit option or just taken a cab.

Try it out!
