seeing cumulative steps

Apple doesn't give a cumulative total. I'd suggest using a third party app such as StepsApp to view it on your phone.

If you click on "Y" it gives you the last 12 calendar months, not a particular year, so, it's really a moving average. There's no easy way to compare year-over-year unless you remember to check the number on January 1. And, it isn't even really the last twelve calendar months. Health its currently showing me April 2021-April 2022.

And, there is no year-to-date option, which is what the OP actually asked for (and I missed in my first answer) However, in an app such as StepsApp, I can see the number of steps I've take so far in this year.

On your iPhone tap on:

Health > Summary (at the bottom) > Steps > Y (at the top

and you will see a daily average for the year. Multiply that by 365 (or the number of days so far in the year) and you will have the cumulative steps for that year.

Looks like a nice app. What is it called?

Its called Fitness stats,been using it for a few years now.

Thanks! Will definitely add the to the toolbox.

I use this app you can enter any between dates you like;

Health app/browse/activity/steps

and at the top tap on Y for year.
