It is a simple, powerful, and completely private tool built to just work - one-time purchase, no subscriptions, no ads. RECORD OR IMPORT Capture practice straight from the camera, or import existing videos from your photo library. Even large videos come in with clear progress so you always know what is happening. ORGANIZE YOUR LIBRARY Keep source videos, trimmed clips, and saved comparisons together in one place. Tag anything, search your whole library in seconds, and favorite the clips you use most. ANALYZE WITH PRECISION Scrub frame by frame, slow footage down to 0.1x, speed it up to 16x, and step one frame at a time to catch the exact moment. Draw freehand, lines, arrows, rectangles, and circles, and add text directly on the video to explain technique. Crop, zoom, and rotate to focus on what matters most. MEASURE BALL SPEED Use the built-in Ball Speed Calculator to mark start and end points on a clip and estimate speed for tennis serves, baseball pitches, or custom distances. Save the measured result back onto the video as an annotation for easy review and sharing. COMPARE TWO CLIPS Study two clips side by side, top and bottom, or in a transparent overlay so you can line up form and timing frame by frame. Each clip keeps its own playback speed and scrub control. EXPORT & SHARE Save annotated snapshots and export comparison snapshots or videos when you are ready to share feedback with an athlete or team. PRIVATE BY DESIGN Your library stays entirely on your device. No account, no sign-up, nothing uploaded. Available in English, Simplified Chinese, Japanese, Korean, French, German, and Spanish.
