Please include your iPhone model and iOS version — it makes problems much faster to track down.
PitchOverlay lays two pitching clips on top of one another and draws the flight path of the ball in each, so you can see how two pitches differ out of the hand. Everything runs on your iPhone — clips are never uploaded.
Ball detection and clip alignment are automatic, and they will not always be right — that is why the app lets you correct them by hand. PitchOverlay is a training and presentation aid, not a measurement instrument. Please don't rely on it for officiating, scouting decisions, or anything that needs measured accuracy.
Your clips are yours. They never leave your device, and we never receive a copy of them. You are responsible for having the right to record and share the footage you use, including the consent of anyone identifiable in it — which matters particularly when you are filming minors.
Two things are requirements, not preferences — clips that break either of them will not track:
Beyond that: shoot both pitches from the same spot and keep the phone roughly still through the pitch. That is what lets the two clips line up.
Ball detection is automatic but not perfect — a ball that blends into the background or gets lost in motion blur can be missed. You can fix it by hand: open the overlay from the main screen, choose Edit Overlay, tap a video, then Edit Ball Positions. Step through frames and tap where the ball is. Your corrections are saved and used when you re-process.
The clips are aligned by matching the background between them, so they need to be shot from roughly the same position. Two pitches filmed from opposite sides of the mound can't be stacked. If the alignment drifts, filming from a more consistent spot usually fixes it — a tripod helps but isn't required.
The two clips are synced at the moment the ball is first detected, and the overlay runs as long as the shorter clip allows on both sides of that moment. Recording a little extra before and after each pitch gives you a longer result.
Use the Playback Speed slider on the overlay screen before tapping Process. It ranges from 0.5× (half speed) to 2×, and the estimated length of the finished video is shown next to it.
Tap it on the main screen and choose Delete. This removes the overlay and the clips it was made from, and can't be undone.
PitchOverlay is free to use with no limit on how many overlays you create. Free exports carry a small PitchOverlay watermark. Pro removes it.
Open Account (the icon at the top right of the main screen) and tap Restore Purchases. Make sure you're signed in with the same Apple Account you subscribed with. Overlays created before subscribing keep their watermark — re-process them from Edit Overlay to get a clean copy.
Subscriptions are billed by Apple, not by us. Open Account → Manage Subscription in the app, or go to Settings → your name → Subscriptions on your iPhone. Cancelling at least 24 hours before the period ends stops the next charge; you keep Pro until the current period is over.
Refunds are handled by Apple. Request one at reportaproblem.apple.com.
PitchOverlay collects nothing. Your clips, the ball positions in them, and the overlays you create stay on your device and are never uploaded. Deleting the app removes everything it stored.
