Looking for some examples for hr vs time and kcal rate targets

[StevieGUK]

Hello,

I am looking to create an app or watch face that can report the following... 

60% of my maximum heart rate for 1 hr (if this is true report it using an alert) 

70% of my maximum heart rate for 30 mins (if this is true report it using an alert)

If possible I would also like to do kcal burn rate reporting...

Example 300kcal/hr (if true report it) 

I am unsure the best approach for this so hopefully you guys/gals will have some examples or resource links I could steal! 🙂

Thanks for your time,

Steve

I don't think you'll find anything which has your exact requirements. The Moment sample demonstrates  heart-rate, heart-rate zone, and resting heart-rate. 

https://github.com/Fitbit/sdk-moment/blob/master/app/simple/hrm.js

It also demonstrates the activity data

You'll need to track this data over time yourself though.

Well I do some work with heart rate percentage with my CooperTime (StripesTime on Github) watchface. In my case I was using it to convert heart rate to "rpm" but the math is the same for you. You can then keep track of how long it stays above a specific %.

The kcal/hr would probably be web api + math.
