Hi Ray, after being a paid TrainingPeaks user for more than 5 years, I finally decided to switch to intervals.icu. Doing so, I've really started to like its better integration for metrics (they call it wellness data, see screenshot) into the calendar etc.

With an app like Healthfit you can sync basic data for sleep, rhr and HRV from Apple Health to intervals.icu but there is quite a bit of stuff missing which could be delivered by superset and thats where my feature suggestion comes in:

I'm not sure if you are interested and providing such integration into 3rd party platforms but I think it would be really neat to be able to sync superset data over to intervals.icu, to be able to use it in plots, graphs and the calendar view.

Obvious candidates for synced metrics would be:

API seems properly documented on first glance:

For an even deeper integration you could implement some kind of morning report that prompts the user for some subjective measures (motivation, mood, subjective stress, soreness) - those could also be synced to intervals.icu and generally those subjective metrics would be nice to have in superset as an addition to the measured ones imo.

I think such integrations could also make your app interesting to a a new set of users which may otherwise never have considered installing superset.
