I believe they can be used offline, at least the last time I used Garmin I was able to set it up such that I could sync it to Golden Cheetah. It took some jumping through hoops and an older watch version to get it work, as I recall. For serious runners and hikers, the hardware is better than Apple.

I'm only a casual fitness tracker so the Apple Watch fits my needs better.
