Good, but..

I use this as a first responder and it helps a lot, but can you look into giving directions for both northbound and southbound specifically? Right now it usually just defaults to northbound.

Thank you for the review. Dual directions is available in many states, but not all yet. Send us a message with which state and routes you need and we’ll move that along sooner.

Great for EMS

I have been using this app for about a year now working on an ambulance. It works great for interstate calls with mile markers in unfamiliar areas, easily locating the mile marker and having the directions automatically take you there on apple maps.
