BangleJs2 Fitness tracking

[Neys-Code]

Hey all together

Since a few days i got my bangleJs2 and i am lacking of some functions i am really used to and which i would love to see. Maybe one of you already did smth similar.

I would love to have a constant step tracker, wich also works consistently with Gadetbridge.

Also I need a calorie calculator, estimating the output calories from heart rate steps and workout type.

In General it would be nice to have a complete workout tracking function.

Did anyone of you already turned the watch into a fitness tracker ? I would love to hear some experience.

As long as you've got the Health app and Android Integration then you should get reliable step counting. Someone did mention an issue with the sync to Gadgetbridge (if you spend time with the watch not connected to the phone) but I believe that can be fixed up by choosing Sync All under the per-device Gadgetbridge settings - the watch is storing step+movement+heartrate data every 10 minutes regardless of connection state.

There does appear to be an app for calorie counting already, but I'm not sure how it works: https://banglejs.com/apps/?id=burn

I had a quick google and there seem to be some relatively simple calculations based on heartrate available: https://www.easycalculation.com/formulas/heart-rate-calorie-burn.html

So something like that could definitely be added - you could use the health library to get all 10 min health records for the day so far
(https://github.com/espruino/BangleApps/blob/master/apps/health/lib.js#L93) and then sum up the calories burned? I wonder whether it almost makes more sense for it to be in Gagdetbridge though? The raw data (steps/hrm) is being sent and stored there and calorie counting in Gadgetbridge would then apply to any watch, not just Bangle.js

One thing we don't do right now is report activity type back to Gadgetbridge (although I have added the ability for Gadgetbridge to receive it) - Bangle.js doesn't store it at the moment, but it does at least know the difference between worn/not worn, normal use, and 'sport' (where it considers the movement threshold above a certain value). I'm not sure how we'd detect other things but we could add an option for the user to manually set the sport type.
