Works great!

We get milepost location as part of fire and accident reports. This helps exactly locate where the fire/accident is located

Response from developer

Thank you for the review! There are 2 widget styles available to choose from and add to your stacks. There is now a full CarPlay version available too. 👍

Awesome

What a great app, it’s very useful. One thing I recommend they do with the next update is add the speed limit and this app will be gold! Thanks for making my life easier.

Almost perfect

The new update to store personal markers has made the app extremely useful as an inspector. Really wish we could set default states as looking across multiple jobsites over a period the app will refresh and have you scroll through the states and route types quite a bit.

Response from developer

Thank you for the feedback. We’re looking at more options for favorites and sorting to make it easier as the lists grow.
