More Money please ,


Downloaded this while driving through Texas/south towing our RV. The roadside historical markers were of interest but not practical to pull over for. Figured this app would be the answer, not so much. We've reached NV now and finally it has some roadside markers that show up for us to read while driving by. Needs additional roadside entries.

Good, but bug...

I was excited to get the app today but discovered a major flaw. Every marker I click on pulls up an almost invisible bubble outline. It took me a while to even see it and then took much longer to realize these bubbles are suppose to be text filled to allow me to see what I clicked. Clicking on the near invisible bubbles does take me to the desired page, but the process is needlessly difficult. Either clicking on the marker itself should open the page, or the bubbles should be more obvious with text. Can this please be fixed, as it is clearly a bug? Thank you.

*As a side note, I have sent this as an email to support and have since gotten 3 “failure to send” notifications over the past week. This means the email you have set on the support page does not work properly.

Developer Response ,

Hi Czilla85. Thanks for bringing this to my attention. It looks like these bugs started happening with one of the recent iOS updates. I'm working on a fix and should have it ready for release in about a week, so hopefully that will clear up both pin popup and email problems. Thanks again and I hope you can continue enjoying the app!

Fantastic App!

I'm so happy that I found this app. It's simple and works as advertised.

My wife and I use it on our road trips through the Appalachians and it's become an indespensible resource for learning about local history. I've written Dan (the author) a couple of times to report bugs and always recieved a quick response. My only suggestion would be to include the ability to upload new images of markers, but Dan tells me that feature is in the works, so fingers crossed.

It's a great app and definitely 5 out of 5 stars!
