I don't own an iPhone, yet I own an Apple watch. Yet I can't get Strava on my watch without owning an iPhone for some reason, so I have to put in my activities manually. This means I miss out on heaps of features, and my idea is that it should be available to connect Strava straight from an Apple watch to a computer/iPad.
If this happens, heaps more people will get to record their runs and more accurately sync them to Strava, and right now there are not enough ways to sync to Strava. You can sync straight from a Garmin, so why not a smart Apple watch?
