Strap it to your ankle and play. Every kick, sprint and jump is tracked, scored and turned into a player card you'll actually want to show off.
You finish a session sweating and satisfied. But did you sprint more than last week? Hit the ball harder? Favour your right foot the whole match? Nobody knows, so you keep repeating the same session and calling it progress.
Ask any player how many kicks they took in a match. The honest answer is "no idea." The real answer, from one prototype session, was 42.
"Tough session" usually means tired legs, not high output. Only one of those actually makes you better.
Most amateurs massively over-use their strong foot and never notice, because nothing is counting.
The sensor sits in a soft band around your ankle, above the sock line. It doesn't touch your boot, so it works with every pair you own, and you stop feeling it after about a minute.
A 6-axis IMU samples your motion continuously and logs the whole session on board. No phone in your pocket, no signal needed, nothing to press while you're on the pitch.
Afterwards it syncs over Bluetooth and the app breaks the session down: kicks, jumps, sprints, intensity zones, fatigue. Then it stacks that against everything you've played before.
Everything below is an actual training session recorded on the prototype: 48 minutes of finishing drills, 19 July.
We show our error bars. Ball speed is estimated from foot rotation, not measured directly, so we print ±10-15% next to it instead of hiding it. Every number on this page comes from a real recorded session.
Kilometres, kicks and jumps all convert into XP. Your card levels up, your skill ratings shift, badges unlock. One tap and your mates can see it.
We're building the first batch now. Join the waitlist and you'll be first to know the moment it's ready — no payment, no commitment, just an early spot.
No payment, ever, to join. One email when the waitlist opens for real. Leave any time in one click.
No. The sensor records the whole session on board and syncs over Bluetooth afterwards. Leave your phone in your bag.
It's an estimate, not a direct measurement. We derive it from the rotation of your foot at contact (ω·r), which lands within roughly ±10-15%. That's good enough to track your own progress session to session, and we print the margin next to the number rather than hiding it. If you need lab-grade ball speed, you need a radar gun, not a wearable.
Yes, all of them. The sensor sits on an ankle band above the sock and never touches your footwear, so grass boots, turf shoes and futsal trainers all work with zero setup change.
The strap adjusts down to youth sizes and there's nothing sharp or heavy in the design. Most of our prototype testers are adult amateurs, so that's who we've tuned it for so far.
Nothing. You've paid nothing and promised nothing — you're on a list. When the first batch is ready we email you once, and you decide then. We'd rather tell you late than ship you something half-finished.
Yes. CSV export of every session, including the raw metrics. It's your training, it's your data.
