Normally I wouldn’t link to this until it’s confirmed, but this is interesting and exciting. I’ve used HopStop whenever I’ve been in New York and it is great. I really hope it finds it way into the Maps app soon and I really really hope they don’t pull it from the App Store until then.
Alternate Quip: Remember when iOS 6 shipped without native transit directions and people thought it would be a boon for third parties? Those were actually auditions.
