hi - if you like the routes suggested by 1, try https://cyclema.ps/hello - disclaimer, i'm part of the team behind it.

Looks really nice - congrats on the app :). I can't test it since I don't use iOS. But if you ever make an android or web browser version - happy to play :)

As a cyclist, I would never plan routes on a tiny phone screen with a crappy UI. I would always plan on a computer and then use the phone to keep me on track.
