Key takeaways
- Clean and dry the coat before fitting any adhesive or strap-mounted sensor; mud and sweat cause drift.
- Check strap tension after the first trot-up; girth and saddle-mounted units settle once the horse moves.
- Record gait, speed, and surface in the app notes every session; without context, asymmetry numbers are hard to interpret.
- Recharge after every use if the device uses a small internal battery—sensor batteries degrade faster than phone batteries and a flat unit mid-exam wastes a vet visit.
Quick Comparison: Best Wearable Lameness Sensors for Horses
There is no single “best” wearable lameness sensor for every yard. The right choice depends mainly on where the sensor sits (poll, withers, back, or all four limbs), whether you need real-time stride data or a periodic clinic-style report, and how easily you can keep the hardware charged and clean. Horse owners and veterinarians are increasingly adopting systems such as Equinosis Q with Lameness Locator, the Sleip app, Alogo Move, and Equimetrics Sensalert, but these tools are decision aids only—they quantify asymmetry and stride data to support, not replace, a veterinarian’s clinical examination.
| Product / class | Sensor placement | Gait data captured | Reporting style | Typical battery life | Approx. price range |
|---|---|---|---|---|---|
| Equinosis Q with Lameness Locator | One sensor on poll, one on sacrum, one on right forelimb (three inertial sensors) | Vertical head and pelvic movement asymmetry, stride timing, +/- values by limb | Veterinary software report, real-time and post-exam; proprietary analysis | Handheld unit runs several hours per charge | Clinic-level equipment; typically several thousand dollars per system (quote-based) |
| Sleip app (iPhone/Android with motion sensors) | Phone/armband carried by handler; no horse-mounted sensor | Handler gait symmetry and speed trends via phone motion data | App trends, graphs, and notifications; training and recovery monitoring | Depends on phone battery; all-day use usually needs a top-up | Consumer subscription app, roughly $10–$30 per month |
| Alogo Move (AlogoMove) | Single sensor integrated into a girth or saddle attachment, depending on configuration | Stride length, symmetry, jump/landing metrics, locomotion asymmetry | App dashboard with symmetry scores and session history | Multi-hour to multi-day depending on configuration; USB rechargeable | Sensor plus subscription; roughly $100s for hardware plus monthly fee |
| Equimetrics Sensalert | Sensor unit on the horse (commonly back / saddle area) | Motion and gait-adjacent data used for monitoring and alerts | App alerts and reports aimed at owners and yard managers | Days to weeks depending on reporting interval; rechargeable | Entry to mid-range, roughly $100s–low $1,000s |
| Camera / marker-based gait analysis (e.g., Equine Gait Analysis in clinics) | Markers on horse plus calibrated cameras; no wearable on the horse during recording | High-speed video digitisation of stride, limb angles, and movement symmetry | Software reports with frame-by-frame metrics; usually vet-supervised | N/A (mains-powered or laptop-based) | Clinic service; per-session fee or equipment purchase in the $1,000s |
The Best Overall: Equinosis Q with Lameness Locator
Who it suits
The Equinosis Q system is the closest thing to a reference standard among veterinary lameness sensors. It uses three inertial sensors—one on the poll, one over the sacrum, and one on the right forelimb—to measure vertical head and pelvic movement asymmetry. Because it references the horse’s own movement rather than a fixed camera, it can be used in a straight line, on a lunge, or under saddle, which matches how veterinarians actually examine a horse. It suits clinics, referral practices, and performance yards that need objective, repeatable asymmetry values.
Our top picks

Main trade-off
The trade-off is cost and workflow. The hardware is clinic-grade and priced accordingly, the analysis is proprietary, and it is designed to be operated by a trained professional. It is not a consumer gadget you clip on and forget; it requires correct sensor placement and a consistent examination protocol. Per the manufacturer’s documentation, the system is intended to augment, not replace, the veterinarian’s visual assessment.
Best Budget and Everyday Option: The Sleip App
Who it suits
The Sleip app turns a smartphone into a motion sensor: the handler carries the phone while trotting the horse, and the app analyses the handler’s own gait symmetry as a proxy for the horse’s movement. It is the cheapest way to start collecting objective trends, and it suits owners who want to monitor a horse through rehab or a training block without buying dedicated hardware. It is also the easiest option to use with no fitting or charging of horse-mounted sensors.
Main trade-off
The trade-off is that the sensor is on the human, not the horse. That introduces handler variability—how you hold the phone, how tired you are, how fast you trot—so the data is best read as a trend over many sessions rather than a single precise measurement. It is a monitoring tool, not a diagnostic device, and it should not be used to self-diagnose lameness.
Best for Saddle-Based Monitoring: Alogo Move
Who it suits
Alogo Move is a horse-mounted sensor that attaches at the girth or saddle, depending on configuration, and records stride length, symmetry, and jump/landing metrics. It suits riders and trainers who want feedback during ridden work, where a poll-and-sacrum clinical setup is impractical. The app dashboard gives symmetry scores and session history, making it useful for tracking a horse across a season.
Main trade-off
The trade-off is placement sensitivity. A girth-mounted sensor can shift with saddle fit and girth tension, so readings can drift if the setup changes between sessions. Riders also need to be consistent about gait, speed, and surface. It is a training and monitoring aid, and any persistent asymmetry it flags should be followed up with a veterinarian.
Best for Yard-Level Alerts: Equimetrics Sensalert
Who it suits
Equimetrics Sensalert is aimed at owners and yard managers who want motion-based monitoring with app alerts and reports rather than clinical metrics. It suits larger yards where staff cannot visually assess every horse every day and want an early flag when a horse’s movement pattern changes.
Main trade-off
The trade-off is resolution. Alert-style systems prioritise detecting change over quantifying it. They can tell you something has shifted, but they will not give the limb-by-limb asymmetry values a veterinarian needs. Treat the alert as a prompt to book a professional assessment, not as a diagnosis.
How to Choose: A Decision Matrix
Use the table below to match your situation to a system class. Prices are general market ranges and vary by region, subscription terms, and whether hardware is bundled.

| Single horse in rehab, budget under ~$50/month | Sleip app | No hardware, instant trends, easy daily use | Roughly $10–$30 per month |
| Performance yard tracking ridden work | Alogo Move | Saddle/girth-mounted, ridden gait metrics, session history | Hardware plus monthly subscription |
| Large yard needing early alerts | Equimetrics Sensalert | App alerts and reports for many horses at once | Per-horse or per-yard subscription tiers |
| One-off detailed gait investigation | Clinic-based camera/marker gait analysis | Highest spatial detail; vet-supervised interpretation | Per-session fee, no hardware to maintain |
Sensor Placement: What Changes and Why It Matters
Placement is the single biggest factor in data quality. A poll sensor captures head nod, which is the classic indicator of forelimb lameness. A sacrum sensor captures pelvic hike, which flags hindlimb lameness. A limb-mounted or saddle-mounted sensor captures stride-level data but is more exposed to slipping, rubbing, and dirt. Camera-based systems avoid on-horse hardware entirely but require a controlled track and markers. Whichever system you use, keep placement identical between sessions; moving a sensor by even a few centimetres changes the readings and makes trends unreliable.
- Clean and dry the coat before fitting any adhesive or strap-mounted sensor; mud and sweat cause drift.
- Check strap tension after the first trot-up; girth and saddle-mounted units settle once the horse moves.
- Record gait, speed, and surface in the app notes every session; without context, asymmetry numbers are hard to interpret.
- Recharge after every use if the device uses a small internal battery—sensor batteries degrade faster than phone batteries and a flat unit mid-exam wastes a vet visit.
What Wears Out First: Durability and Ownership Realities
Across wearable sensor systems, the consumable that fails first is usually the attachment hardware: elastic straps lose tension, hook-and-loop fasteners clog with hair, and adhesive pads stop sticking after repeated sweat exposure. The second most common failure is the battery. Small lithium cells in horse-mounted units typically deliver a few hundred charge cycles before capacity drops noticeably; treating the unit as a “charge after every session, store at half charge” device extends its life. The third issue is software drift—app updates can change how metrics are calculated, so export and save reports rather than relying on the app to show historical values. A practical maintenance routine is: rinse straps in plain water (no detergent residue, which can irritate skin), air-dry fully, wipe sensor housings with a damp cloth only, and check firmware before each vet visit. Common mistakes include leaving sensors on overnight, using them in heavy rain without checking the IP rating, and comparing readings taken at different speeds or on different surfaces.
What the Data Can and Cannot Tell You
Wearable sensors quantify movement asymmetry and stride characteristics. They cannot tell you the cause—foot pain, joint disease, muscle soreness, or a poorly fitted saddle can all produce similar asymmetry patterns. A veterinarian combines sensor output with palpation, flexion tests, nerve blocks, and imaging to reach a diagnosis. Use sensors to establish a baseline when the horse is sound, to track response to treatment, and to decide when to call a professional. Do not use them to delay that call. If a horse shows sudden, severe, or worsening lameness, contact a veterinarian promptly regardless of what the app reports.
Frequently Asked Questions
Can a wearable lameness sensor diagnose my horse?
No. These devices measure movement asymmetry, stride timing, and gait metrics, but they do not identify the cause of lameness. Diagnosis requires a veterinary examination that may include palpation, flexion tests, nerve blocks, and imaging. Use sensor data as supporting information for your veterinarian, not as a substitute for their assessment.
How many sensors does a typical system use?
Clinical systems such as Equinosis Q use three inertial sensors—poll, sacrum, and one forelimb. Consumer systems often use a single horse-mounted sensor at the girth or saddle, or no horse-mounted sensor at all if the phone is carried by the handler. More sensors generally mean more spatial detail but also longer setup time.
How long do the batteries last?
It varies widely. Clinic handheld units typically run for several hours per charge, enough for a day of examinations. Horse-mounted consumer sensors often last from several hours to multiple days depending on reporting interval and configuration. Phone-based apps are limited by the phone battery, so all-day use usually requires a top-up.
Do I need a subscription?
Most consumer systems combine hardware with a monthly or annual subscription, typically in the range of roughly $10–$30 per month for app-based services, with higher tiers for multi-horse yards. Clinic-grade systems are usually a larger one-off purchase with no consumer subscription. Always check what happens to your data if you stop paying.
Where should the sensor be placed?
Follow the manufacturer’s instructions exactly, and keep placement identical between sessions. Poll and sacrum placement captures head and pelvic movement asymmetry, while girth or saddle placement captures stride-level data. Moving a sensor even a few centimetres changes the readings and undermines trend comparisons.
Can I use a sensor without a veterinarian?
You can use consumer monitoring systems on your own to track trends over time, and many owners do. However, any persistent, sudden, or worsening asymmetry should prompt a veterinary assessment. These tools support professional evaluation; they do not replace it.
