AXIS43 · the softball pitch lab
Scout the pitcher your team faces on Saturday and let your hitters and catchers read her pitches at real speed, on their phones. Or dial in speed, spin, axis and wind and watch any pitch fly, spin and break in 3D.
€4.99 for a full season
A riseball, dropball and changeup in 3D, from the catcher's view.
Spin is invisible at 65 mph. AXIS43 slows it down, draws the axis and shows the force it creates.
Hitters and catchers train against real-speed pitches until they read them before the ball arrives.
Every number is physics you can check: scores per pitch for coaches, exports and a versioned model for research.
Pitch IQ · face any pitcher
Scout her once: which pitches, how often, how hard, and what she throws with two strikes. Pitch IQ throws exactly that arsenal at real speed, from the catcher's or hitter's eyes, and makes the ball vanish at the decision point.
The questions coaches and players ask first, answered.
Yes. Scout her once: which pitches, how often, how hard, and what she throws with two strikes. Then your hitters and catchers face her in Pitch IQ, at real speed, as often as they like.
Yes. Pitch IQ throws pitches at real speed from the catcher's or hitter's eyes. The ball vanishes at the decision point, and you answer before it arrives.
Catch it is made for catchers: tap where the ball will cross the plate before it gets there. You score by how many inches your glove was off.
That is what it is built for. Your licence covers your own lessons, team practices, camps and clinics.
Every Season Pass comes with a cloud pitch library: up to 250 pitches that follow you to your laptop, tablet and phone.
Wind is part of the physics, in any direction and speed, and you can watch the air move through the 3D scene.
Yes. The model is documented, versioned and calibratable, and every export carries its inputs and model version.
It runs in any modern browser, on a phone, tablet, laptop or the TV in the clubhouse. No headset, nothing to install and no account to make.
Prepare your hitters for the pitcher they face this weekend.
Train your eyes between practices, on your phone.
Understand your own pitches before you throw them.
From "how does a riseball work?" to a thesis with real numbers.
Wind, visualised
Outdoor softball is never played in still air. Here the same fastball is thrown with the same release, once in calm air (grey) and once through a 15 mph crosswind blowing towards third base (yellow).
A fastball drifting in a 15 mph crosswind, next to the same pitch in calm air.
Spin-tracking hardware costs hundreds to thousands and needs a pitcher in front of it. AXIS43 works with any pitcher, before anyone throws.
Pick a built-in archetype or scout your own: her pitches, her mix, her speed, her out pitch. Pitch IQ throws exactly that arsenal.
Gravity, drag and the Magnus force from spin, solved 2,000 times per second with air density from temperature, altitude and humidity.
Spin rate, break direction on a clock face, gyro angle and seams with 88 stitches, spinning around the real axis in slow motion.
Catcher's eyes at real speed, batter, side, top, pitcher or follow-the-ball. Orbit, zoom and scrub frame by frame.
Wind from any direction moves the ball and the air around it. A compass shows where it blows; a metric shows how far it moved the pitch.
Cloud pitch library, overlays, fullscreen coach mode, printable pitch cards, parameter sweeps and reproducible exports.
These are the equations AXIS43 solves for every pitch. The model is versioned, so results stay reproducible.
m·a = m·g + F_drag + F_Magnus
Integrated with a fourth-order Runge–Kutta solver in 0.5 ms steps, from release to the catcher's glove.
F_drag = −½·ρ·A·C_D·|v−w|·(v−w)
Forces act on the velocity relative to the air: v − w, with w the wind. Air density ρ follows from temperature, altitude and humidity.
F_M = ½·ρ·A·C_L·|v−w|²·(ω̂ × v̂)
C_L depends on the spin factor S = r·ω⊥/|v−w|, from the bilinear fit of Sawicki, Hubbard & Stronge (2003) or a saturating curve, scalable to your own data.
efficiency = |ω⊥| / |ω|
The axis stays fixed in space while the path curves, so spin efficiency changes during flight, just like real pitches with gyro spin.
One payment of €4.99 / $4.99 for twelve months. No subscription: it never renews by itself.
€3.27 per player
Scout Saturday's pitcher once and send her to your team in one link. Anyone can face her for five pitches free; with a pass, every player trains against her all season. The Team Pack covers the whole roster in one payment.

Both, with different jobs. Coaches scout pitchers, run the team on it and present on the dugout TV. Hitters and catchers train their eyes in Pitch IQ on their own phones. Pitchers use the lab to understand their spin.
AXIS43 solves the equations of motion for a 12-inch (or 11-inch youth) softball with drag and Magnus lift, using published lift and drag fits for seamed balls. Trends and magnitudes match softball tracking data well, but no model captures every seam, ball and release. Treat results as a physics-based estimate, not a radar reading.
No. The archetypes are fictional pitchers with speeds and spin inside public high school to college ranges. Your own scouted pitchers are yours and stay with your licence.
Every pitch is decided by its spin axis, and fastpitch is pitched from 43 feet. AXIS43 is where those two meet: the axis that bends the ball, over the distance a hitter has to read it.
No subscription. One payment of €4.99 unlocks twelve months of every pitch type, full spin-axis, release and air controls, Catch it and all Pitch IQ levels, every archetype, your own scouted pitchers, the cloud library and the research toolkit.
A pass is personal: one coach or athlete, on all of their own devices. Use it freely in the sessions you run. To train the whole team, every player gets their own pass of €4.99, and your share link puts your scouted pitcher on all their phones.
Nothing is charged. Two weeks before, we e-mail you a link to add another season. If you do not, the free lab and Pitch IQ on Rookie stay open, and your pitches and pitchers wait for you.
Use "Restore access" above. We e-mail a one-hour link to the address you paid with; your library and pitchers come back with it.
