Both @shanekingsley and I use The largest verified route archive thanks to MyRoute-app RouteXperts to create routes and convert them to GPX files.Is there a go to app for routes and GPX files?
I have the free version and it works well for my needs.
If you pay for it there are additional features. One of the main differences, IMO is that the map interface is the Google maps version and not their own. Their own map interface comes with the Free.
You can also pay for the navigation portion which will also allow you to use the navigation map as a GPS.
I have been meaning to pay for the lifetime subscription but I'm having a hard time justifying it. Maybe because its a subscription and not a physical item like a jacket or accessory.
All your routes are saved there and you can modify them on the fly, share them with others, make them public etc.
SK wrote about it enough times in other threads.
Give it a try, free version does not expire. Be warned, you may not like the map interface that they use. We are all used to the Google interface.
I often have the Google map on once screen and this site on the other.
