I am now in the process of downloading Maps Pro and will try to figure this one out too. Looks like you have to pay a small fee ($4.99) for the APP and then pay for each set of maps you download โ looks like US and/or North America is $9.99 but I am still trying to figure it out. It appears they also use Open Street Maps. Based on user comments below it sounds as though the developer is constantly working to improve this. Could be something up and coming. Here is what I have found so far.

very basic
who ever said "replacement for streets and trips", must not of have ever used S & T. no draw tool. no route optimization. can't import from excel .xle. xlms. I would like to import all my contacts from a spreadsheet, decide which area I need to go to that day, enclose THAT area ONLY with a draw tool, pick my start, pick my stop, then let the program optimize my route. Maps Pro has potential. Delorme street atlas is cumbersome. How about just buy the discontinued S & T rights from Microsoft and just continue map updates. Or just copy its functions. Thanks.

Map does nothing but from A-B. Can not use more than two locations. Also can not save map. Great for Kindergarten Kids to learn on. "WHERES MY STREETS AND TRIPS"?

Very useful Mapping App with multiple options
A bit clunky to use... but it's usefulness outweighs difficulties. I use it WITH Google Maps, thus giving me the utility of both. This program offers an extraordinary array of choices with stunning clarity, including Topo's, Hiking/Biking Trails, Useful Overlays, on and on. We are Full-Time RV's and wouldn't be without it.

Lacking basic settings
Looks to be very promising but not there yet. I used Streets and Trips for years and loved it. It let you change routes to roads I wanted to travel. This app limits that and only shows a couple different routes to travel. Please add this option for your next upgrade.

Versatile Navigation Package
This is an outstanding product. You have access to download a very inexpensive set of street maps for the whole US and Canada for use offline. You also have online access to many types of maps from multiple sources, e.g., highly detailed satellite imagery, shaded relief, topo, street, and hybrid maps from Google, Bing, Open Street, CalTopo, and more. You may also download sections of these maps for free. I'm using a combination of the base street maps, topo maps, and satellite imagery for on and off-road navigation. Works great on my Windows 10 tablet with the Dual XGPS150A GPS puck. Primary reason for 5 stars instead of 4 is the excellent support from the author. I was having trouble getting my GPS to pair with the OS and app. As usual, it was a bit of user error on my part. The author responded the very next morning to my initial email and again at the end of the day to another email from me. Support is often overlooked and yet so valuable an aspect of any application.
