Make the flight visible

A pitching session,
with more context.

Set the camera once. Capture the pitch. Review what the camera saw, alongside the flight model.

  • 01
    Camera follows the ball

    High-speed frames and measured camera placement support a physics-based flight fit.

  • 02
    Optional radar adds reported speed

    Radar is off by default. Enable it in Advanced settings to add a compatible Bluetooth radar’s speed reading.

  • 03
    Spin keeps its evidence

    Surface tracking and movement-based inference are presented as separate methods.

From the field to the screen

Built for a
measured setup.

The geometry matters. A fixed phone, a clear view and a few real measurements give the analysis its starting point.

01 / PLACE

Choose your angle.

Mount the iPhone at release height, behind the pitcher or catcher, with enough sideways offset to see the ball.

02 / CALIBRATE

Measure the field.

Enter the camera placement and follow the calibration points before recording.

03 / REVIEW

Keep the evidence.

Review release and flight frames. Save footage and available analysis in the local pitch library.

Two ways to examine spin

What moves.
What rotates.

Movement can inform a spin estimate. Visible surface features can provide rotation evidence. Flight43 keeps that distinction visible.

SURFACE TRACKING

Follow the ball’s features.

Track visible seams or optional asymmetric marks across frames to estimate surface rotation when the images support it.

PHYSICS INFERENCE

Use the shape of the flight.

A gravity, drag and Magnus model estimates transverse spin from fitted movement. It does not establish total spin or gyrospin.

These methods are under development and have not yet been field validated. Lighting, blur, visible detail and calibration affect whether a result can be produced.

Planned launch offer

Your first 50 pitches.
On us.

Start with 50 successfully analyzed pitches free. Continue analyzing with an App Store subscription after that.

Flight43 is in development. This is the planned launch offer; subscription billing and the free-pitch allowance are being added separately. Planned U.S. pricing is $5/month or $50/year. Local plans and prices will be shown before purchase. The 50-pitch allowance is a one-time starting allowance, not a monthly reset.
