Please add turn by turn audio directions so we don’t have to always be looking at our phone while on an activity. I’d personally use this for cycling but I imagine it’s useful for many other activities as well.
If you need to save battery you could turn your phone screen off and navigate purely by the audio directions. (For activities where you may be watching the app mid-activity, like cycling)
Saves you from the disruption of pulling out your phone for directions mid-activity. Stay in your flow!
Not having to look at your phone in a busy area is safer, especially on a bike.
Completes Strava as a navigation app, meaning less need for other devices, and people are more likely to subscribe for Strava Premium.
