is there an app which allows you to create a route on a smartphone and use on your ride?
I bought the garmin explore, was impressed but didn't feel it gave me significant advantage over my current set up so returned it.
The one feature I liked was the routing. I currently use a garmin 800 edge as an onboard computer, a garmin vivoactive 3 watch to log the ride, using the 800 as a back up and my iPhone to help if I get lost.
I wondered if I could use an app or similar to give me the routing option I'm now missing?
I could use the 800 but it's not great for routing and needs plugging into a computer
Based on your two posts there are a couple of ways to interpret your request.
Are you looking for an app to plot a route (in advance) on your phone and send it to your edge to follow? (In other words, it saves you faffing about with a computer)
Or
Are you looking for an app that will let you plot a route mid-ride which you then follow either on your phone or your Garmin?
For what it's worth, OSmand has been my back up navigator for a few years now (touring).
It is a PITA to get used to, but once you are familiar with it, it is a brilliant piece of kit giving turn by turn (voice) directions as well as POIs and (for me) it's killer application is the fact that it will create routes on the fly with
no internet access. By the way, you can also use it in the car.
I tested Komoot and RidewithGPS locally (NL) and while RideWithGPS is handy for looking at other people's routes, I wasn't a fan of either's routing. Cycle.Travel is for me, the best routing engine - but that's only online - not an app.
