Stand hours, stand minutes, steps and exercise minutes: what each Apple Health number means
For anyone looking at the Activity section of Apple Health and wondering which number to trust for a day at a desk.
Open the Activity section of the Health app with an Apple Watch paired and you will find several numbers that all sound like they describe the same thing: whether you moved today. They do not. Each one is a different measurement with a different threshold, and mixing them up is how people end up with a closed ring and a stiff back on the same day.
Here is what each one counts, as plainly as Apple’s own pages allow.
Stand hours
The number behind the Stand ring. An hour counts when you “stood and moved for at least 1 minute” in it (Apple Support, Track daily activity), and the default ring wants twelve of them (Apple, Close Your Rings).
It is a yes or no per hour. Ten minutes of walking at 10:05 and one minute at 10:58 produce the same result: one stand hour. That makes it a good answer to “did I get up at all this hour” and no answer to “how much did I move”. The separate post on the twelve-hour goal goes through why a full ring is twelve minutes of movement, not twelve hours.
Stand minutes
Less well known, and more useful. Alongside the hourly yes or no, the Watch writes the minutes it judged you to be up and moving. Where stand hours round everything to a whole hour, stand minutes keep the amount.
In building an app that reads this data, I found it arrives in short blocks of a few minutes rather than as a running total, and well ahead of steps. A walk shows up as stand time several minutes after it ends, while the steps for the same walk can take far longer to reach the iPhone. That makes stand minutes the quickest sign in Health that you just got up, even though they say nothing about how far you went.
Steps
The most familiar number and the one with the most going on underneath. Both your iPhone and your Watch count steps, so on a normal day Health is receiving two overlapping counts. It does not add them together. Health ranks its data sources and, when several provide the same kind of data, the one at the top of the list takes priority; by default, your own iPhone and Watch rank above third-party apps, and you can reorder them under Data Sources & Access (Apple Support, Manage Health data).
Two practical consequences:
- Leave the phone on the desk and only the Watch sees the walk. That is the ordinary case at work, and it is why a step count from the phone alone looks low on desk days.
- Watch steps reach the iPhone on their own schedule. In my own testing the Watch’s steps for a short walk took anywhere from about ten minutes to half an hour to appear in Health on the phone. They always arrived; they were not instant.
Steps are the best measure of whether you actually went somewhere. They are a poor measure of when, minute by minute, unless you wait for them to settle.
Exercise minutes
The green ring. It counts minutes of “brisk activity” (Apple Support), which Apple’s ring page describes as activity “at or above a brisk walk”, with a default target of 30 minutes (Apple, Close Your Rings).
The key word is brisk. A slow walk to the kitchen and back usually earns nothing here, because it is not brisk. That is correct for what the ring is for, and it means exercise minutes say almost nothing about a sedentary working day. You can sit for eight hours, run for thirty minutes in the evening and close the green ring, and you can get up twenty times at work and earn none.
Active energy
The red Move ring measures active calories. It responds to everything, but it is a total for the day, so it cannot tell a morning spent in a chair followed by an evening walk from a day spent moving steadily.
Which one answers “have I been sitting too long?”
None of them directly, which is the honest summary. Each answers a neighbouring question:
| Number | Answers | Blind spot at a desk |
|---|---|---|
| Stand hours | Did I get up at all this hour? | One minute counts the same as forty |
| Stand minutes | How many minutes was I up? | Says nothing about distance or when I sat back down |
| Steps | How far did I go? | Watch steps arrive late; phone steps miss walks without the phone |
| Exercise minutes | Did I move briskly? | Ordinary walks around the office rarely count |
| Active energy | How active was the whole day? | A daily total, not a pattern |
The question that matters for a desk job is about time since you last got up, which is a pattern across the day rather than a total at the end of it. That is the same point the post on how often to get up from your desk makes from the other direction.
Putting them together
Office Shrimp is an iPhone app that reads two of these, step count and stand time, from Health (read-only), alongside the iPhone’s own motion history. Stand time is the fast signal: it holds the next reminder back as soon as you have been up. Steps are the slow, firm one: they are what count a walk as a break. Every walk resets the clock, so reminders follow when you last got up rather than the hour on the clock, and only during the working hours you set.
It does not write anything to Health and does not touch your rings, so the numbers above stay exactly as Apple records them.
iPhone, iOS 18 or later. Apple Watch optional. Now on the App Store.
Nothing here is medical advice. Apple’s definitions are quoted from Apple’s own pages; the timings in the stand minutes and steps sections are from my own testing on one iPhone and one Watch, not from Apple.
