Citymapper

Citymapper is designed for urban transport: In other words, it helps you find the right bus ride, subway train, or other transit option that’s right for you. It also gives you options for the best trip routes, current service outages, and more. You wouldn’t think that these features are watch friendly, but somehow the app does a fantastic job of communicating exactly what you need to know, from where you are to which train/bus you need to get on next – all with just a glance.
