If you are planning a trip along the Chesapeake and Ohio Towpath, then don't leave without your C&O Companion.

The information found on the popular BikeWashington.org canal website is now available in an app. Simply sync and go. No data connection required when you are on the path.

While on the towpath, the C&O Companion will display your current location, and will help you find amenities along the way. It also has self-contained maps that do not require a data connection.

In the event of an emergency, the C&O Companion will help identify your location, and the quickest way to reach help.

Proceeds support the C&O Canal Trust Fund.


Troubleshooting: Less than 1-in-500 users have reported one of these problems with the application:

a) Won't report location. If your app is stuck on "Finding Location" (and you are not in airplane mode), then this generally means that you did not allow the C&O Companion access to your current location. (A dialog box will ask your permission during first launch). This is easy to fix. Just open the "Settings" application (this app came with your device; it has the gray "Gears" icon) and look for "Location Services". Ensure that Location Services is ON, and that is has been enabled for the C&O Companion application.

b) Sync never completes. Just one person reported that after pressing the Sync button, the download never completed. This is most likely due to a corrupted database. We fixed this by simply deleting the app and then using the iTunes application to reinstall the app from iCloud (no additional change is incurred for re-install). This procedure wipes out the database so you can start over fresh.

Won’t sync

Just downloaded this app. Keeps telling me to sync for first time use. I’ve done that multiple times to no avail. I have the map section but no listings for amenities. Very frustrating especially since this isn’t a free app.
Update August 4th. App now syncs. Wish it was done sooner before I completed my C & O trip but better late then never. I did enjoy the map function while on the trail

Developer Response ,

Apologies. Unfortunately, there was a server fault which prevented operation of the application. This was recently identified and corrected, and additional monitoring has been put in place to prevent a repeat of this incident.

The app should now be fully functional after performing a SYNC operation.

Great App

Just rode the C&O from Cumberland to DC for the second time, and it would have been nice to have this app 10 years ago! Stopped at Barron’s Store for ice cream and snacks, and talk with the Tyler family...it was the last day of the season as they were closing a bit early this year. I let them know about the app and they were happy to see it and the details being published for the store. Also used the app to plan exit and dinner at Buddy Lou’s in Hancock and check the trail status in a couple areas that were closed 10 years ago and one area the Tylers told me was a slight detour due to a washout of the trail. Otherwise it is a great reference and is up to date, and it does sync for me... Also used it to track down mile 0 marker that I missed 10 years ago. Great app and worth every penny!
