Thank you to everyone who wrote me about the recent bug that cause the app to crash when using location services in iOS 10. Version 3.5 should solve this problem!

I've implemented the ability to favorite individual markers and a feature to help distinguish previously viewed markers, as suggested in the reviews. If you would like to share more suggestions on how to improve the app, or if you encounter a bug, please feel free to contact me at [email protected] or tweet ideas and/or comments to @MarkersApp.

Also, please note that Historical Markers aggregates data from the Historical Marker Database and the U.S. National Registry of Historic Places. If a local marker is not in either of these databases, it will not appear in the app. If you would like to add a local marker to the Historical Marker Database, please visit http://www.hmdb.org. The ability to upload marker information and pictures directly from your iOS device is coming in a future release!
