1. Give your iPhone a clear side view
Place the iPhone securely outside the sideline, level with the area where you will hit. Keep your head, feet, racket, and the full swing in frame. The phone does the recording; an Apple Watch is optional.
The camera setup guide covers framing, distance, light, and common placement problems.
2. Hit one focused block
Choose forehands, backhands, or serves and follow that drill’s rep target. Dropshot counts repetitions and stops at the target, or you can end early and review usable strokes from the attempt.
A steady feed gives you more useful comparisons than a random mix of balls. This is focused practice, not match scoring or line calling.
3. Let the phone find each stroke
Dropshot identifies the movement, measures what it can see, and runs individual technique checks on your iPhone. The result comes from defined rules, not an unexplained guess from the video.
Clear framing matters more than cinematic video. If the phone cannot see enough of the swing, there may not be enough information for a useful check.
4. Review the swings that made up the session
Move from clip to clip, play, pause, scrub, slow the video down, and read the checks beside each stroke. Overview then zooms out to the totals for the whole practice.
5. Learn the cue, then try it again
The best feedback makes the next practice simpler. Look for what repeats, choose one adjustment, and open a related video lesson when you want to see the idea explained. Then try another round under similar conditions.
