Docs inform us to try to get 10,000 steps a day, however virtually nobody makes use of a pedometer to verify. As an alternative, we depend on our health smartwatches to inform us once we’ve hit our purpose. However ought to you belief your watch’s step counter accuracy?
I made a decision to check this for myself. I strapped on six smartwatches directly — an Apple Watch Collection 6, Galaxy Watch 5 Professional, Garmin Forerunner 265, COROS APEX 2 Professional, Fitbit Sense, and Amazfit T-Rex Extremely — and walked laps round my neighborhood whereas counting each single step in my head (and oh boy, was it tedious).
As soon as I hit 5,000 steps, I in contrast the real-world quantity towards what every watch stated. Then I ran an extra 1,000 steps, checking to see if it was any kind of correct if I used to be transferring at a sooner tempo with longer strides.
So, are smartwatches correct for step counting? It is determined by which model you personal.

In his new weekly column, Android Central Health Editor Michael Hicks talks in regards to the world of wearables, apps, and total health tech associated to working and well being.
I particularly subtracted any “steps” taken earlier than the take a look at began. This made the beginning circumstances equal, but additionally erased the commonest reason behind step-counter inaccuracy: watches’ accelerometers and/or gyroscopes measuring “steps” from you simply transferring your arms round as a part of each day life.
That apart, right here have been my smartwatch step counter take a look at outcomes after strolling 5,000 steps and working 1,000 steps:
- Amazfit T-Rex Extremely: 5,046 strolling, 984 working
- Apple Watch: 4,940 strolling, 1,050 working
- COROS APEX 2 Professional: 5,070 strolling, 989 working
- Fitbit Sense: 4,714 strolling, 994 working
- Garmin Forerunner 265: 5,014 strolling, 999 working
- Samsung Galaxy Watch 5 Professional: 5,074 strolling, 1,039 working
Ignoring the Fitbit Sense‘s surprisingly inaccurate strolling outcomes for a second, you’ll be able to see that the majority of those watches fall inside a ±100-step vary of the true end result — or double that for 10,000 steps. So in the event you exit for a stroll and hit 10K, you’ll be able to typically assume you are not too far off the mark.
The working outcomes solely look extra correct at first look; quintuple the distinction, and you may see how, specifically, the Apple Watch Collection 6 and Samsung Galaxy Watch 5 Professional battle to precisely rely working strides, in comparison with strolling. Devoted working watches do higher, together with Fitbit (regardless of its early step-counting struggles).
Rating them for closest accuracy, the Garmin Forerunner 265 is the clear winner, simply 15 steps off in whole and solely 1 off for working monitoring. Amazfit’s flagship watch (62 steps off) and the COROS APEX 2 Professional (81) take second and third place, each predictably doing effectively for working information. Apple (110), Samsung (113), and Fitbit (292) take up the ultimate three spots.
[Before anyone gets up in arms, I’m aware the math says Apple was only 10 steps off 6,000 because it was 60 short for walking and 50 long for running, the two inaccuracies canceling each other out. That’s not how I chose to measure accuracy, because someone either only walking or only running wouldn’t get a super-accurate result.]
As a closing level, I additionally stored an Android cellphone (the Samsung Galaxy S22+) in my pocket throughout my stroll/run, as a baseline to match and see in the event you do not even want a smartwatch for step counting. The outcomes? 5069 and 998. That final end result positively stunned me, because it did much better than Samsung’s personal top-tier watch. Usually talking, it is fairly correct, about on par with Amazfit and COROS; you simply do not get all the different health-tracking advantages {that a} smartwatch presents.
Analyzing my completely unscientific smartwatch step-counting take a look at
I had no thought how tedious it might be to discover a bunch of useless watches sitting in my closet, discover all of the proprietary charging cables, recharge and replace them one after the other, sync them to my Android cellphone or iPhone, after which squeeze three watches onto every wrist. In idea, a watch being barely greater on my arm may have affected the outcomes a bit, so I did my finest to mitigate that and stored them shut collectively.
Then I walked in 93º climate whereas all of my neighbors gave me very judgy and confused stares (aka “Why the heck is that this weirdo sporting six watches? Is he the Clock King?”), making an attempt to maintain rely in my head whereas retaining a constant strolling tempo.
So, yeah, I thought about doing the take a look at once more, presumably with different watches from the identical manufacturers, or simply to see if the winners and losers have been constant. However no manner am I doing it once more, sorry buddies! You may attempt the experiment at dwelling your self to see what outcomes you get, if you’d like.
I do not personal (or could not match) each smartwatch model; I missed numerous Put on OS watches like Pixel Watch, TicWatch, and Fossil Gen 6, in addition to different working manufacturers like Polar.
Furthermore, I haven’t got the newest variations of sure manufacturers’ flagship watches just like the Fitbit Sense 2 or Apple Watch Collection 8. However to be truthful, you virtually by no means hear something a couple of watch’s accelerometer being X% extra correct than the final technology in advertising and marketing supplies. It is not clear what number of manufacturers are literally enhancing them from yr to yr, now that they’ve hit a sure baseline of accuracy.
The purpose is, that is hardly a scientific take a look at, and also you might need very completely different outcomes relying in your top, strolling stride, cadence, and different elements. Plus, like I stated earlier than, on a regular basis false positives for steps are an actual downside.
Despite the fact that the Garmin Forerunner 265 received the battle for step accuracy, I’ve observed my step rely climbing when doing nothing however sitting at my desk. One thing so simple as stretching or pointing at one thing can set off it. And when strolling and not using a pure arm movement, comparable to once I’m holding a cellphone in my hand, the shortage of back-and-forth motion can befuddle the accelerometer.
The purpose is, in the event you do need to stroll 10,000 steps a day, or no matter step rely your watch’s well being algorithm recommends, chances are you’ll need to take false steps under consideration and stroll a pair hundred further steps, simply to be secure. Although in Fitbit’s case, you’ll be able to assume you are already effectively above 10K when you hit it.
My private step rely common during the last six months is, mockingly, 6,000 steps (give or take 100 steps, I suppose). My purpose is to try to hold elevating that quantity by the point I hit 2024, as I attempt to enhance my VO2 Max and different metrics.
So I am completely satisfied that my each day Garmin watch, the Forerunner 265, is fairly darn correct on step counting, even when they nonetheless have room for enchancment. Add to that the truth that it is additionally among the many most correct in terms of GPS monitoring, and it is no fluke that it sits on the highest of our finest working watches listing.
However for individuals with normal life-style watches just like the Apple Watch or Galaxy Watch, 200 steps off the mark after 10,000 whole is not so horrible that you need to assume significantly about switching manufacturers. It is simply one thing to concentrate on!
Why correct step counting issues
Based on a research by the Journal of American Medical Affiliation, strolling 10,000 steps a day results in diminished threat for heart problems, most cancers, or mortality typically for older sufferers. The NIH discovered that for hypertension sufferers, three months of each day strolling reduces your common systolic rating by about 10 factors.
Constant strolling can enhance cognitive operate and reminiscence, in accordance with an Alzheimer’s journal research, in addition to your temper. Your muscular tissues are strengthened, combatting pure muscle weak point and shakiness from growing old. It not solely makes contracting Kind 2 diabetes much less doubtless but additionally helps stabilize your blood sugar if in case you have diabetes.
Plus, in fact, there’s the plain profit that strolling about 5 miles will burn a whole lot of energy — doubtless someplace between 300 and 600, relying in your weight and tempo.
All of this helps clarify why so most of the finest health smartwatches incorporate step counting into their watch faces and well being snapshots. It is the one metric that offers well being advantages throughout the board, particularly for middle-aged-and-older customers going through severe illnesses.
