Thanks for posting this. This looks promising...

I have about 3-3.5 years worth of Apple Health + Fitness data (via my Apple Watch) encompassing daily walks / workouts / runs / HIIT / weight + BMI / etc. I started collecting this religiously during pandemic.

The exported Fitness data is ~3.5GB

I'm looking to do some longitudinal analysis - for my own purposes first, to see how certain indicators have evolved.

Has anyone done something similar? Perhaps in R, Python? Would love to do some tinkering. Any pointers appreciated!

Thanks!!

It might actually be worth writing your analysis in Swift with the actual HealthKit API and visualization libraries.

Bonus: when you’re done, you’ll have an app you can sell.

FWIW, we're working on something similar (you wouldn't necessarily need to write R or Python). Feel free to email me at bmb@empirical.health and I can add you to a beta once we have it ready!

    Thanks, I'll reach out.

    I am curious to do my own analysis, for two main reasons:

    - some data is confidential (I'd hate for it to leave my devices) - wanna DIY / learn / iterate

    Will ping you in any case. Thanks
