Surely one of the best data fields one can use for running. The graphs and additional stats one gets in the activity are very helpful. Comparing changes in running index over the time is good stat to track.

Could you please add support to new watches like forerunner 970? Thanks in advance

Is it possible to integrate Heart rate stress score also to this data field? As most devices allows only 2 data fields, I use Stryd as one of the datafields and would love to have Running index and HRSS also.

I really love this data field and have used it on my Epix Pro. I just bought the Fenix 8 and it doesn't seem to be supported yet; any chance you'll consider updating it to support the Fenix 8 at some point? Thanks for the great work!

Great app! Question.. I assume you have to manually update your heart rate setting as your data changes? I just realized, I have not been using my max up to date heart rate. My garmin 245 updates connect automatically.
