    Now that Watches are trickling in, what are people's experience with the exercise app and in particular the heart rate monitor? Does the HR sensor operate continuously and if so what is the sampling rate? Also does HR drop during activities that would jostle it (ie trail running or mountain biking?

    During exercise, HR monitor is always on. The sample rate is 100 per second.

    I wish I can use the watch to monitor my heart rate for when I'm looking outside my window waiting for the UPS truck to get here with my watch.

    I found it outstanding on my first run. It seemed very accurate to me, and it was great being able to access it so easily.

    I had no idea how it was going to work until I read a few days ago the way it does actually work. It's pretty neat!

    Does anyone know if the heart rate monitor works with apps like map my fitness and strava? I read somewhere that apps don't have api access to the heart rate sensor...they can only access the data through healthkit. Is this accurate?

    I'm wondering if i'll be able to track a run or bike ride with strava using the phone and watch without having to use a separate heart rate sensor.

    Alternatively, can strava access and import the gps and heart rate log created by the fitness recording watch app?

    Just did my first stepper workout with it, while also using a Wahoo Tickr connected to my iPhone.

    Watch matched the strap readings within +/- 3 BPM until I did a wee bit of vigorous arm waving. Then it went a little nutty, showing 75-95 while I was doing 150 to 165BPM. Might have to tighten the strap, or maybe it was sweat.
