Made for softball
Made for the videos you actually take.
TrueVelo is built for softball and for the phone already in your hand. Film from behind the catcher, beside the field, or wherever you can see the pitch. Record something new or use a clip that is already in your camera roll.
Use any angle
If you can see the ball leave the hand and either hear the mitt pop or see the catch, TrueVelo has the two moments it needs.
Standard or slow-motion
Regular iPhone video works. Slow-motion gives you more frames when you want to fine-tune the measurement.
Import what you filmed
Measure a new pitch or start with a clip someone already sent you.
How it works
Two moments. One clear number.
Set your distances once. Then TrueVelo measures every pitch the same way: flight distance divided by flight time.

Why it works
Trust the number because you can see how it was made.
TrueVelo does not hide the measurement behind a mystery score. It shows the release, the catch, the elapsed time, the distance, and the calculation. If you want to change either moment, you can—and the answer updates with it.
THE PHYSICS40 ft÷0.467 s=58.4 mph
Distance divided by time. The same visible calculation for every pitch.
Every frame is timed.
Apple’s video system attaches timing information to recorded video frames. TrueVelo reads those timestamps between release and catch.
How Apple represents video timing →Video catches what the eye misses.
Pitching happens too quickly to judge moment by moment. High-speed video turns motion into evidence you can replay and inspect.
How professional pitchers use high-speed video →The physics stays simple.
Once flight distance and time are known, speed is distance divided by time. Slow-motion adds finer control; standard 30 fps video is fully supported.

Straight answers.
Everything you need to know before the first pitch.
Do I need a tripod?
No. TrueVelo is designed for the phone in your hand. Hold it steady when you can, but no mount, stand, or fixed camera position is required.
Can I film from any angle?
Yes. The measurement needs two moments: the ball leaving the pitcher’s hand and the catch. Keep the release visible and the mitt pop audible for the clearest automatic detection. If you can see the catch but the sound is unclear, mark it yourself. Behind the catcher is a helpful filming tip—not a requirement.
What if TrueVelo does not detect the pitch automatically?
Set the release and catch yourself, frame by frame. The app shows both moments and updates the speed immediately. Manual adjustment uses the same distance-over-time calculation as automatic detection.
Does slow-motion footage work?
Yes. Standard and slow-motion iPhone video both work. Slow-motion gives you more frames to choose from when you want the finest timing control.
How does TrueVelo calculate speed?
TrueVelo measures the time between release and catch using the timestamps in the video, then divides the pitch’s flight distance by that time. You can see the distance, elapsed time, release, catch, and resulting MPH in the app.
Can I use a video I already have?
Yes. Import a clip from your camera roll and measure it just like a pitch you record in TrueVelo.
Where do my videos go?
Your videos and measurements stay on your iPhone unless you choose to share them. TrueVelo does not upload them to a TrueVelo account or cloud service.
Is TrueVelo made specifically for softball?
Yes. TrueVelo is designed around fastpitch softball: the windmill delivery, the mitt pop, and the 35 ft, 40 ft, and 43 ft pitching distances used across age groups.
Is TrueVelo accurate?
TrueVelo is designed to give you a consistent, inspectable measurement. It uses the timestamps attached to your video frames and a visible distance-over-time calculation. Results depend on entering the correct distance and identifying release and catch; both moments can be checked and adjusted in the app.
