Tracking Your Horse to Soundness
Film ten seconds of trot on your phone. EquiLogic compares how far your horse’s head and hips move on one side against the other, tells you which leg the difference sits on, and puts a number on it from 0 to 5 — the same lameness grade your vet uses, so you can set today’s against last month’s.
$14.99 for a single analysis, and no subscription unless you want one. A screening aid, not a diagnosis.
Head height, one stride
Schematic. Not a reading of any horse.

of frame
At grade 0 the head drops the same distance on both beats. Nothing to measure.
What it is for
Let us help you find subtle lameness and determine which part of a horse’s limb may be contributing to pain.
A horse may look sound at a walk or a normal trot.
Narrow down which part of the limb may be contributing to pain, so an examination starts closer to the answer.
Regular examinations can help your vet recognize changes over time, especially in performance or older horses.
Finding a developing orthopedic issue before it becomes severe may allow for earlier treatment and potentially prevent worsening.
The measurement
Left fore lands with right hind, then right fore with left hind. The head drops as each pair takes the weight, and on a sound horse it drops the same distance both times.
Pain breaks the pattern. A horse with a sore front foot lifts its head as that leg lands and drops it harder onto the good one. Behind, a sore hind shows up as a hip that rises further on one side than the other. Grooms have read this for a very long time and gave it a name: down on sound.
The difference is usually small. In the example beside this, the head drops 4.1% further on one beat than on the other. That is measured as a share of the height of the picture, so it means the same thing whether you filmed from ten feet away or thirty. It is also a horse most people would call level, watching it trot away across a yard.
Measuring that difference is arithmetic once you have the frames. Catching it by eye, on a moving animal, from the ground, at the end of a long day, is a different job. That is the whole of what EquiLogic does for you.
What this does not do
It does not know why. A shoe that has moved, a stone bruise, a hock beginning to change and a horse that was simply fresh that morning can all produce the same number. Naming the cause is a veterinary examination, and this is not one.
From the app
Every circle sits on a point it genuinely followed through your video. If it could not pin something down on the frame, it says so in words instead of drawing a guess.
Three steps
Ten seconds of trot, in hand and from the side, on flat even ground. Nobody in the saddle, because a rider changes the very thing being measured. Pan smoothly to follow the horse. The app watches while you record: it reads the light, how steady the phone is, and how much of the horse is in frame, and tells you to fix it while the horse is still out.
One tap sends it. Before anything is charged, the clip is checked for length, steadiness, and whether you have sent this exact video before. A clip too short, too dark or too shaky to read is turned away before you pay for it, not after.
Minutes later the report opens on your phone. It leads with what to do about it, then shows the working underneath: the grade, which leg, the exact spots on your own footage it measured, and how today compares with this horse’s earlier readings.
The report
A few minutes after you send the clip, a report opens on your phone. The first line is a plain instruction: keep an eye on it, book an examination, or call your vet today. Everything below that line is the evidence for it.
A whole report, top to bottom. Example horse, example numbers.
Nobody films their horse because they want a grade. They film it because they want to know whether to pick up the phone. So the report opens with one of three answers — keep an eye on it, book an examination, or call your vet today — and sets out the reasoning directly underneath.
A number from zero to five, the same scale your vet uses, with plain words beside it so it is not left to guess at. Underneath sits every earlier reading for this horse, because a two on a horse that has always been a two and a two on a horse that was a zero last month are not the same news.
Share it, email it, or save it as a PDF. The message that goes out carries the horse’s name, the score, the date and the caveat, so it makes sense to someone who has never heard of this app.
Circles drawn on your own footage, on the points it tracked — the top of the head, the top of each hip — with how far each one rose and fell. You can check it against what you half noticed in the school. Your vet can look at it and decide whether to believe it.
The leg the difference sits on, marked on a photograph and on a simple diagram of the horse seen from above. Left and right are the horse’s own left and right, the way a vet or a farrier says them, and near side and far side are labelled on both.
Over time
A score on its own tells you very little. The same score set against this horse’s last six months tells you almost everything you wanted to know when you got the phone out.
You add each horse once, and every clip you film gets filed under it. The readings then line up in order, and the app works out which way they are heading and how fast. A horse that has slipped half a point over eight months and a horse that has slipped half a point in nine days both look worse than where they started, and only one of them is a phone call tonight.
Most of what makes a history worth having costs nothing. Adding a horse is free. Noting down how it seemed today, in a few taps, is free. Telling us what your vet found after you sent them a report is free too, and it is the most useful thing you can do, because it is the only way anybody finds out whether a reading was right.

The trend
The record
Each horse has a five-step checklist for building up a useful history: add the horse, get a first reading, get a second one weeks later, keep noting how it seems day to day, and tell us what the vet found. Only the two readings cost money, because there is no other way to get them. Nothing on the list rewards you for uploading more clips than your horse needs.
Limits
Read this part before you buy anything. If it changes your mind, it has done its job.
A horse can be sore and read as level, particularly when it hurts on both sides at once. Even lameness cancels out: the head nods equally on both diagonals and the measurement finds nothing to report.
A rough surface, a horse that is tense or fresh, a handler jogging unevenly, a camera that moved. All of them can put asymmetry into a clip that has nothing to do with pain.
The report names a limb and shows the movement it measured there. What is happening inside that limb is a question for hands, flexion tests and imaging, and none of those fit in a phone.
Filmed on a surface and in a light we did not control, of a horse we have never seen. That is worth something, and it is worth much more with three more like it.
EquiLogic is a screening aid. It is not a veterinary examination, it is not a diagnosis, and it is not a substitute for one. We do not claim veterinary accuracy, and we will never tell you your horse is fine.
For vets
Every sentence in this product was checked against one test: would a vet reading it beside an owner object to it.
What arrives is a clip, a grade, the limb, and the vertical excursion measured at each tracked landmark, with the horse’s own history attached where there is one. It is written in clinical language and it states its own confidence, including when the read leans on half a clip because the horse drifted out of frame.
Nothing in it recommends a treatment. Where the decision is anything other than keep watching, the recommendation is to book an examination, and the summary is built to be pasted into a message rather than described down the phone by an owner repeating a number they did not understand.
When an owner tells us what you found, that answer is kept against the reading. It is the only feedback that means anything, and it is free to give.
The handoff
The caveat travels with it, because a grade that arrives without one is a grade somebody will act on alone.
Price
One analysis is one credit, bought when you need it and used whenever you get round to filming. If you are keeping an eye on a horse month to month there is a plan that works out cheaper per analysis, and nothing on this page requires one.
Buy an analysis on its own, whenever you want one. It sits in your account until you use it and it never expires, so one bought tonight is still there next spring.
A lower price per analysis, refilled on the same day each month. Unused credits reset at the end of the cycle, which is what pays for the discount.
Before you spend anything: adding a horse, filming with the guide, logging check-ins and reading the example report are all free and do not need a card. A clip that is too short, too dark or too shaky to read is refused before a credit is taken, and a clip you have already analysed is recognised rather than charged for twice.
Questions
Anything not covered, or a question about the $14.99, is worth an email.
You make an account, add your horse, and film ten seconds of it trotting past you while the app talks you through the shot. You send the clip. A few minutes later a report opens on your phone telling you whether to keep an eye on the horse, book an examination, or call your vet today, with the score, the leg and the measurements behind that advice. Adding the horse and reading the example report cost nothing, so you can look around before you buy anything.
It is the standard lameness scale a vet works to. Zero is sound, one is subtle, two is mild, three is moderate, four is marked and five is severe. The report puts the word next to the number, and the number on its own is never the point: what matters is which leg it sits on and whether it is different from the last time you filmed.
Minutes, not days. Upload the clip and the app tells you when the report is ready, including if you have closed it and walked off.
The horse in hand: led on foot at a steady trot, on a loose lead, past the camera. Ten seconds or so, filmed from the side, on flat and reasonably even ground. Stand in one spot and pan smoothly with the horse so the whole horse stays in frame for the whole pass. The app checks the clip while you are recording and again before it charges you, so you find out on the spot rather than after you have paid.
No, and this is the one that catches people out. A rider changes the thing being measured: their weight and rein contact alter head carriage, stride length and rhythm, and a good rider holds a lame horse together well enough to hide it. A ridden clip still gets a score, and that score cannot be trusted. Get off, hand someone the phone, and jog the horse past them on a loose lead.
No. It reports how much a movement differs between one side and the other, and which limb that difference sits on. What is causing it is a question for a veterinary examination.
It is the opposite. Most of what it produces is designed to be handed to a vet, and where the reading is anything other than keep watching, what it tells you to do is book an examination.
It sometimes will be. The report states its own confidence and says when it could only read part of a clip. If a vet examines the horse afterwards, telling us what they found is free and takes a moment, and it is the only way anyone finds out how often we are right.
Credits you buy outright do not. Credits that come with a monthly plan reset at the end of each cycle, which is why a plan costs less per analysis than the same number bought outright.

Tracking Your Horse to Soundness
Ten seconds of trot, and a reading you can put in front of somebody qualified. $14.99 for the first one.
A lameness score does not automatically mean anything is majorly wrong. These results are most useful when interpreted by a veterinarian rather than as a standalone test.
