Fantastic

We used this app from Texas to Taos New Mexico. While my husband drove, I would look for historical markers and read them to him. Even when they’re not close to the road, you can still read them from the app. It kept us busy and it was fun to learn his historical information on the area.

Waste of money

I was so excited for this app but I basically flushed money right down the toilet! Anytime I click on something for more information, it crashes.

Terrible

Crashes. Not worth the money.

Disappointing - crashes constantly

Crashes every single time a location historical marker is selected. Every. Single. Time.

Thanks for originally pioneering this idea;

It’s still a great idea; sorry it turned out to be unworkable to maintain. Sure was a step up from low at official state highway maps for approaching markers or worth a detour… Helpful while it worked; deleting the excess 2.5M …
Thanks for trying
3* for a good idea that worked for a while years ago
