Worth Getting it?

Hello,

I found that some of the Samsung S features may fill some of my needs however I have a few questions:

1. Does it work well with Note 3?


2. I would like to use it for fitness, is it any good for that? (running, indoor exercise,)


3. is there any standalone app that can be used for running (without phone)? I know that in Android wear we can use ghostracer and endomodo. Is there anything like that?


4. Is it worth getting it now for 289 €?

Thanks :)
