Features
Physics, not guesswork..
No AI estimates, no cloud magic. Baseball Radar measures distance over time, using your bat's real length as the on-screen ruler.
Your bat is the ruler
Tee-ball, youth, BBCOR, wood, softball or fungo — pick your bat and its real length calibrates the scene. Fine-tune it to match your own.
Record or import
Shoot with the built-in high-framerate camera, or import any slow-mo pitch or swing already in your gallery.
Slow-motion aware
Slow-mo metadata is detected automatically, or set the factor yourself — 1×, 1/2×, 1/4×, 1/8×, 1/16× — so the math always stays true.
Pinch-to-zoom precision
Zoom deep into the frame to drop calibration and tracking dots with pixel accuracy.
Offline & private

FAQ
Baseball ball speed questions..
Common questions about measuring pitch speed and exit velocity with just an iPhone.
How does Baseball Radar measure ball speed without a radar gun?
Baseball Radar analyses a pitch or swing video frame by frame. You mark the top and knob of your bat — its real length becomes the on-screen ruler — then tap the ball across two or three frames after release or contact. The app converts pixels per frame into real-world ball speed using your device's recorded frame rate. Pure geometry and physics, no AI guesswork.
Is Baseball Radar free on iPhone and Android?
Yes. Baseball Radar is free to download on the App Store for iPhone and iPad, and on Google Play for Android. It works with slow-motion videos you already have in your gallery.
Which iPhone or Android phone do I need for accurate readings?
Any iPhone, iPad or Android phone able to record slow-motion video works. For fastballs above 80 mph, 240 fps slow-mo (iPhone 8 and newer, recent Android flagships) gives the sharpest, most accurate readings.
Can I import an existing slow-motion video into Baseball Radar?
Yes. Record inside Baseball Radar or import any slow-mo clip from your gallery. The app reads the embedded slow-motion factor automatically, or you can set the multiplier yourself — 1×, 1/2×, 1/4×, 1/8× or 1/16× — so the reading stays true to real-world speed.
How accurate is Baseball Radar compared with a real radar gun?
With a stable phone, a side-on camera angle and at least 120 fps, Baseball Radar is typically within a few percent of a hardware radar gun — accurate enough to track progress, compare pitches and benchmark your swing.
Is Baseball Radar available on Android?
Yes. Baseball Radar is available on Google Play for Android, alongside the App Store for iPhone and iPad.
