You can use either a single sensor or a pair:

Even with just 1 tracker, all of your general physical metrics are fully measured across the entire session—including your top sprint speed, total distance covered, accelerations, stamina curves, and overall work rate. However, foot-specific technical metrics—such as shot speed (km/h), ball touches, kick power, and passing volume—are only recorded for the specific foot the tracker is worn on.

Using 2 trackers (one on each ankle) captures data across both feet simultaneously, allowing the companion app to analyze your weak-foot vs. strong-foot touch ratio, two-footed passing balance, and dual-leg shooting power.

Chest vests and smartwatches only track general body movement via satellite GPS and optical heart rate, completely missing foot-to-ball interaction. By mounting high-rate 3D motion sensors directly on your ankle, our tracker records micro-level technical ball metrics—including exact strike velocity, ball impacts, release speed, foot rotational speed, and turning angles—while still logging all physical locomotion metrics.

No. The tracker has built-in high-speed onboard memory that records and stores your entire session locally. Leave your smartphone in your kit bag or locker; once you finish your match or drill, open the companion app and all your data syncs automatically via Bluetooth in seconds.

Yes. Weighing only 25 grams and encased in a low-profile, flexible neoprene wrap, the module sits comfortably under your match socks or grip socks. It contains zero sharp edges, complies with standard match safety gear rules, and causes no interference during tackles, sprints, or strikes.

We recommend strapping it to your dominant striking foot. This ensures you capture the vast majority of your passes, shot velocity measurements, and primary technical touches, while the internal IMU continues tracking your overall speed and work rate regardless.

The sensor provides up to 8 hours of continuous, high-frequency active recording and up to 30 days of standby time. It snaps cleanly into the included magnetic charging cradle and charges to 100% in roughly 90 minutes.

No mandatory monthly subscriptions. Purchasing the hardware gives you permanent lifetime access to the mobile companion app, including session storage, 6D multi-dimensional score sheets, trend analytics, and radar charts at no extra charge.

The companion app connects seamlessly via Bluetooth Low Energy (BLE 5.0). It fully supports iOS 12.4+ (iPhone) and Android OS 9.0+ smartphones and tablets.

Yes. The module is engineered with an IP66 waterproof and dust-tight rating. Paired with our quick-drying, washable neoprene sleeve, it operates flawlessly through torrential rain, mud, artificial turf rubber pellets, and heavy sweat.

Simply slide the sensor out of its slot before washing. The neoprene strap can be hand-washed in cold water with mild detergent and air-dried. The tracker unit itself can be wiped clean with a damp microfiber cloth.
