• Keep the phone still and level. Use a tripod, or lean the phone against your bag, at about the height of your hands at address.
• Get your whole body in the frame, from head to feet, for the whole swing. Leave some space around you, but don’t stand so far away that you look tiny.
• One golfer, one swing. Keep other people out of the shot, and trim the clip to a single swing.
• Use good light and a high frame rate. Film in daylight or a bright room, at 60 frames per second or more if your phone offers it, so your hands don’t blur in the downswing.
• Set your handedness in your profile, so the analysis reads your lead and trail side correctly.

Two views:

• Face-on: the camera square to your chest, level with the ball.
• Down-the-line: the camera behind your hands, looking along the target line.

Each view measures different things, so choose the view you filmed. The app warns you if the video looks like the other view. Plane lines only work down-the-line.

Because it can’t measure them honestly. Swing Smarter measures your body from a single phone camera. The club head moves too fast and too thin for that, and the ball leaves the frame, so club path, club face, ball flight, speed, distance and launch data would be guesses. Measuring those takes a launch monitor.

Plane lines in the down-the-line view show where your hands travel against lines drawn from the ball. They track your hands, not the club.

The analysis checks each video before measuring it. Common reasons for a warning: your head or feet leave the frame, the camera moved, the light was low, the frame rate was low, more than one swing is in the clip, or the video doesn’t match the view you chose. Fix the cause and record again; the tips above cover each one.

Measurements from one camera are estimates of your body positions, and their quality depends on the video. That is why every finding has a confidence level: give high-confidence findings more weight than low-confidence ones. The coaching is written by AI from those measurements and can be wrong. Treat it as guidance, not instruction from a certified professional.

• Put your phone on a tripod at about the height of your hands at address, facing you for face-on or behind you for down-the-line.
• Make sure your whole body stays in the frame for the whole swing.
• Turn the volume up so you can hear the feedback after each swing.
• Between swings, tap Ask and say your question.

Body tracking runs on your phone, and camera frames never leave it. The free plan includes a 5-minute Live Coach taster each month.

New Pro subscribers get 7 days free. During the trial, limits are lower than full Pro: 5 video analyses, 30 minutes of Live Coach, 3 coach messages a day and 2 practice plans a week. The trial turns into a paid Pro subscription unless you cancel at least 24 hours before it ends.

Subscriptions are managed by Apple, so you cancel in your Apple ID settings:

1. On your iPhone, open Settings and tap your name.
2. Tap Subscriptions, then Swing Smarter.
3. Tap Cancel Subscription.

Cancel at least 24 hours before your trial or current period ends to avoid the next charge. You keep Pro until the end of the period you have paid for. Deleting the app or your account does not cancel a subscription.

1. Make sure your iPhone is signed in to the App Store with the Apple ID you subscribed with.
2. Sign in to Swing Smarter with the same account you used before.
3. Open the Pro upgrade screen (from the plan card on the Profile tab) and tap Restore purchases.

If Pro still doesn’t show, email us from the address you sign in with.

In the app, go to Settings → Privacy & data → Export my data. You get a file with your profile, swings, analyses and lessons, with download links to your media that work for 1 hour.

In the app, go to Settings → Privacy & data → Delete account and confirm. Deletion happens immediately and can’t be undone, so export your data first if you want a copy. If you can’t use the app, see deleting your account without the app.

Deleting your account does not cancel an App Store subscription. Cancel it in your Apple ID settings first.

For a video analysis, up to four still frames from your video, the measurements and a summary of your golfer profile are sent to our AI provider, Anthropic. Live Coach and coach chat send measurements and the text of your questions. Your full video and Live Coach camera frames are never sent.

You can turn AI processing off in Settings → Privacy & data; features that need AI then stop working until you turn it back on. More in the Privacy Policy.
