3-IN-1

Your swing, your putting and your body. One sensor, one app.

Three tools usually mean three devices and three apps. Axion puts all of them in one sensor and your phone. iPhone and Samsung.

01 3D SWING

See your swing in 3D

Every swing replayed in 3D, takeaway to finish. Tempo and release through the swing, then face, path and speed at impact.

02 PUTTING

Dial in your putting stroke

Same sensor, on your putter. Stroke speed, tempo, face and path on every putt, so you know whether your stroke repeats.

03 AXION BODY

See what your body did

Prop up your phone and the camera tracks shoulder tilt, spine tilt and head sway. Body and club, on the same swing.

WHY IT'S DIFFERENT

Most misses start before impact.

Takeaway, top, transition, release. By the time the ball is in the air, the cause is already over. Axion measures the club through all of it, so you see why the ball did what it did.

A launch monitor shows the ball

It tracks the ball after impact: speed, spin and carry. Great for what happened, but it can't show how your club got there.

A camera shows your body

Video shows posture and positions, not what the club is doing. You can't read face angle or path from a camera alone.

Axion shows the club

Face, path and speed, takeaway to finish. The cause behind every result. On its own, or next to a launch monitor.

HOW THE APP WORKS

See it. Understand it. Fix it.

A thousand times a second, Axion tracks the club in 3D. The app turns that into four screens: what happened, and what to do about it.

Axion AX1 app, Swing Motion screen: a 3D render of the swing with the club path drawn from takeaway to finish

01 · SEE IT

Watch every swing back in 3D.

Every swing, rendered from the sensor's own data. Scrub through it, switch between down-the-line, face-on and top views, and see where your path left the plane before the ball ever moved.

Axion AX1 app, Shot Result screen: a plain-English verdict above a grid of all 12 swing metrics, with the metric to work on highlighted

02 · UNDERSTAND IT

The verdict first. Then all 12 numbers.

One plain sentence says what the shot did and why: "your face was open to your path, so the ball started left and curved right." Under it, all 12 metrics, with the one that needs work flagged.

Axion AX1 app, metric detail sheet for Face to path: a plain-English explanation, this swing against the target range, and a top-down view of the clubface at impact

03 · DIG IN

Tap any number and it explains itself.

Every metric opens a card in plain English: what it means, what it does to your ball flight, this swing against your target range, and the clubface at impact from above.

Axion AX1 app, AI coach report: your swing type, a session summary and two numbered fixes with a drill to try

04 · FIX IT

Your AI coach tells you what to work on first.

After a session, the coach reads your swing type, sums up every ball you hit, and puts the fixes in order. Work on the first one. Next session, see if the number moved.

Ball flight, spin and distance are calculated from the measured club data, not tracked by radar or camera. Head speed, club path and face angle correlate closely with a commercial-grade multi-camera launch monitor system in driver and 7 iron testing. Axion is not a launch monitor and isn't trying to be one. It shows you the part of the swing a launch monitor can't see. App screens show a sample session.

PROVEN IN JAPAN. BUILT FOR THE US.

Millions of swings in Japan. Now built for American golfers.

This isn't a first attempt. Epson engineered the sensor in Japan and refined it over three generations before bringing it to the US.

Epson built the sensor on its gyroscope technology and refined it over three generations in Japan. Flightpath Golf and Pilesout built the US version together, with swing algorithms made for golf.

It reads how your club moves a thousand times a second, and only records when it feels the club strike a ball. In testing, head speed, club path and face angle correlated closely with a commercial-grade multi-camera launch monitor system on driver and 7 iron.

HOW IT WORKS

Screw it in and swing.

A 12-gram sensor that threads into the end of your grip. No tripod, no camera, nothing to set down behind you. Indoors or out, it records every ball you hit.

IMAGE: Axion AX1 sensor threading into the butt end of a grip

STEP 1

Thread it into your grip

Screw the attachment into the grip, click the sensor on and line up the white mark. Three attachments come in the box, so one can live in each club you work on.

STEP 2

Pair it and pick your club

Open the app, pair over Bluetooth and pick the club in your hands. The numbers calibrate to that club's loft, lie and length.

STEP 3

Hit balls. Every one is recorded.

Range, net, garage or course. It only records when the club strikes a ball, so practice swings don't clutter your history. The battery lasts about six months.

FREQUENTLY ASKED QUESTIONS

Questions, answered.

What does founding member mean?

You get one of the first 200 US units at the founding price and the Axion AX1 app free for life. You also get early access to every app update and a say in what we build next. The US app is new, so we'll ask what you think now and then as it grows. Feedback is optional. You keep the sensor and the lifetime app either way.

Is the hardware finished, or is this a prototype?

Finished. The sensor is made by Epson and is on its third generation in Japan, with millions of swings recorded. What's new is the US app, which works today and will keep improving. Founding members help shape it.

Which clubs does it work with?

At launch, Axion is tuned for your driver, 7 iron and putter, and putting analysis is in the app when units ship in January. More clubs are coming in future app updates. One sensor covers all of them: move it to the club you're working on.

Why am I paying now for something that ships in January?

Your $299 is charged when you order. That holds your sensor in the first US production run, which ships in January 2027, and locks in the founding price and your free lifetime app. After launch, the sensor is $399 and the app is $149.99 a year. Change your mind before it ships and you get every dollar back.

Can I get a refund?

Yes. Get a full refund any time before it ships. If the January date moves, we'll email you the new date first. Your refund stays open until it ships. After delivery, you have 30 days to return it. You pay return shipping.

Is this a launch monitor? Do I still need one?

No, and no. A launch monitor measures the ball after impact. Axion measures the club through the whole swing, so it shows you why the ball did what it did. Ball flight and distance are calculated from that club data. If you already use a launch monitor, Axion fills in the part it can't see. If you don't, Axion stands on its own.

Will it fit my grips?

The included attachment threads into the butt end of a standard rubber grip, and three attachments come in the box so one can live in each club you work on. We're finishing fit tests on midsize, oversize and counterweighted putter grips and will publish the full list before units ship. If yours turns out not to fit, your pre-ship refund covers you.

Is the distance measured or calculated?

Calculated. The sensor measures your head speed, face angle and club path. Carry is worked out from those. It isn't radar or a camera, so think of it as a solid read on your swing, not an exact yardage. If you want measured ball data, use Axion alongside a launch monitor.

Which phones does it work with?

The Axion AX1 app runs on iPhone and Samsung phones. The sensor pairs over Bluetooth 5.0 with about 13 feet of range, so your phone can sit in your bag or on the mat beside you.

Can I use it during a round?

Yes. Leave it on and it records every swing with the club it's on. Under the Rules of Golf you can leave it running and review the data after the round, as long as you don't use it to analyze your swing while you play. Check your club's local rules before competition.

Does it work indoors or into a net?

Yes. Axion senses the club, not the ball, so it works into a net, in a garage or at an indoor range exactly as it does outdoors. There's nothing to set up behind you and no camera to align.

What's in the box?

The Axion AX1 sensor, three club attachments, a case opener tool, a CR2032 battery, and the user manual and warranty card.

Can I buy it as a gift?

Yes. Units ship in January 2027. The lifetime app membership is tied to the account that activates the sensor, so the person who receives it gets the membership. Email us after you order and we'll send a printable gift card you can give now, with the sensor following in January.
