Free Or Good Ball Flight Algorithm Modeler (Click for Photos)

Free, easy to install, see carry distance in an instant. The program was made about 10 years ago so the carry algorithm needs an update and as a result it tends to read carry a bit shorter than other algorithm. I recommend just inputting the ball data under Launch Parameter. And Horizontal Launch Angle (ie Launch Direction) and Side Spin values are flipped in recent terms (ie negative for right side, whereas now is left side). So just be aware of that.

Probably the most popular one due to Flightscope branding, this doesn’t require any program installation. It used to have an inflated carry algorithm issue and that seems to be fixed from this year. But it seems like it’s now actually reading slightly shorter carry than other algorithm.

OptimalFlight

$9.95/year for 1 PC, while it’s not free this algorithm is considered a ‘gold standard’ for accurately outputting carry numbers. Trajectoware referred the data from OptimalFlight, and it looked like a few companies referred as well. OptimalFlight is so far the closest carry distance you see vs Trackman outdoor with full ball tracking. The only downside is you can only input 4 ball data at once and too much information in one page that can be overwhelming for people who are not familiar with data.
