Provides an extremely useful function sadly missing from Apple/Google Maps. I searched a known route and found the info to be very accurate, including cash vs toll pass options. Alternative (cheaper) routes can be accessed after a one-time upgrade fee. However, alternative routes can also be discovered (free) by using the "add Via-point" feature. All the fundamentals are there and the app will greatly benefit from future updates. The ability to export your route to Apple/Google Maps is needed to allow navigation and will take this App from 4 Stars to 5 Stars. Update : The App now supports route export to google maps BUT that function must be unlocked after purchase. This should be a standard feature and does not merit the 5th star when implemented this way.
