I've been off of Strava for a couple of years, and know they've made some big changes. Strava at least used to give you free route planning, but you'll need find a place to clip the smart phone to the bars.
If you get a second smart phone, you can use the Strava offline, but it doesn't do a good job at remembering maps, so you have to scroll around your map when it is online. With certain plans, you can setup a hotspot on one phone for access from a second phone.
One of my problems with Strava is they cut off support for some of the older phones... which includes mine.
