Run at a steady effort, start a stopwatch, and count. Thirty seconds is long enough to be stable and short enough that you will not lose your place. Counting one foot is far easier at speed than counting both, so the tool will double it for you rather than leaving you to remember.

Steps per minute, both feet, the way a watch reports it.
Speed is cadence multiplied by step length, so once you know two of the three the third is fixed. Add the pace you were running and the step length falls out of the same identity.
Raising step rate at a fixed pace shortens the step by the same proportion, because the two must still multiply to the same speed. That trade is the mechanism behind step-rate retraining: Heiderscheit, Chumanov, Michalski, Wille and Ryan, “Effects of step rate manipulation on joint mechanics during running”, Medicine & Science in Sports & Exercise 2011;43(2):296–302, cued runners to lift their step rate 5–10% above their own preferred rate and measured a shorter step and less energy absorbed at the hip and knee.
There is no correct cadence. The figure of 180 comes from Jack Daniels counting step rates at the 1984 Olympic Games and finding almost every finalist above it — a floor observed in elite athletes racing, which then travelled the world as a target for everyone else. Step rate rises with speed and falls with leg length, so a tall runner jogging easily is supposed to be well under it. The percentages above are relative to your own rate for that reason. Change one thing at a time, give it weeks rather than days, and stop if something starts hurting.
Optical and accelerometer-based step detection is good, not perfect, and it goes astray at exactly the moments you care about: on trails, in a crowded start pen, with a hand in a pocket. Counting is boring and it is exact. Settle into a steady effort, start the clock, and count for thirty seconds — long enough that the figure stabilises, short enough that you will not lose count. Counting a single foot is far easier at speed, and doubling it afterwards costs nothing.
At the 1984 Olympic Games, the coach and physiologist Jack Daniels sat in the stands and counted the step rates of the distance finalists. Of roughly forty-seven athletes, only one turned over slower than 180 steps a minute. That observation went into his book, and from there into the internet as a rule.
It was never a rule. It was a floor, observed among elite runners racing, and it says nothing about what a recreational runner should be doing on an easy Tuesday. Step rate climbs with speed and falls with leg length, so a tall runner jogging is supposed to sit well underneath it.
Speed is step rate multiplied by step length. Fix any two and the third is decided for you, which is why this tool asks for a pace as well as a count: with both in hand, the step length is not estimated, it is implied. It also means the two familiar ways of running faster — turning the legs over quicker, or reaching further with each one — are the only two there are.
Step rate is one scalar summarising a movement with dozens of moving parts. It cannot see where your foot lands relative to your hips, how hard it lands, what your knee does on contact, or whether your hips drop. Two runners at an identical 172 can look nothing alike from the side.
It has become popular because it is the one gait variable a wrist can measure, which is a fact about sensors and not about biomechanics. Useful as a dial you can turn, then, and poor as a score to be graded on.
Because the product has to stay equal to your pace, lifting step rate five per cent at a fixed speed shortens every step by very close to five per cent. That is the whole mechanism behind step-rate retraining, and it lands the foot closer underneath the hips rather than out in front of them.
Work in percentages off your own measured rate rather than towards somebody else’s number, change one thing at a time, and give it weeks. A gait pattern rehearsed over years does not move in an afternoon, and forcing it usually just makes something ache.
Whichever you can count reliably. One foot is much easier once you are moving quickly, and the tool doubles it for you, so the only thing that matters is telling it which you did.
Not on its own. Plenty of efficient runners sit in the low 160s, particularly tall ones and particularly at easy pace. It becomes interesting mainly when it comes packaged with a heel landing well ahead of the body and a history of the same injury.
Because you held the same pace. Speed is the product of the two, so if the rate goes up and the speed does not, the length has to come down by the same proportion. There is no way around that arithmetic.
Several weeks of regular, unhurried practice, usually starting with short segments inside easy runs rather than whole sessions. Expect it to feel ridiculous at first and to drift back the moment you stop paying attention.
