BatApp is a simple yet powerful tool for collecting batting speed data without expensive and cumbersome radar equipment. This app provides ball Exit Velocity (EV) and Launch Angle (LA), which is very useful for batting skill development. The innovative user interface allows using the app anywhere - all you need is a line of sight to home plate and the field.
Calculate the Exit Velocity and Launch Angle
The location button finds the diamond map with ease. After pinning the home plate location you're ready for the first hit! Simply press and hold the timer button when the bat makes contact with the ball and release it when the ball lands or is caught. Pinning the location where the ball dropped allows calculating the Exit Velocity and Launch Angle.
Works for baseballs and softballs
The aerodynamic model of BatApp is calibrated for a standard baseball, but it can be used for a softball as well. The exit velocity error for softball usage is less than 1 mph for a 12” circumference softball and less than 0.5 mph for an 11” ball.
Accuracy
While the data model is accurate within ±2 mph and ±2 degrees in over 80% of the time, some conditions such as wind or ball spin may cause deviations beyond these limits. Timing error of 0.2 s translates to about 3 mph and 3 degrees of error and ball drop location error of 10 ft translates to about 3 mph and 1 degrees of error on a typical 200 ft hit.
Pro Tips
The best way to reduce the distance error is to watch the game in the outfield where you can estimate the landing spot most accurately. The best way to reduce the timing error is to... work on your reaction time!
