Above: a real rep, filmed on an iPhone. The see-through outline is the ghost, matched to the player at contact.

How it works

Film. Pick. See.

  1. The clip check in FormWatch: 60 fps, 11 seconds, side view, one player, with the shot picker below.

    Film

    Set the phone on a tripod, side-on, and film a set. Or import a clip from Photos. We check the clip first: frame rate, length and view.

    The clip check, before anything runs.

  2. FormWatch analyzing a forehand drive clip: 3 reps found, 2 of 3 tracked, with a thumbnail of each rep.

    Pick

    Pick the shot, and power or control on a drive. We find your reps and track your body, all on the phone.

    Tracking your body, offline too.

  3. The FormWatch Result screen paused at contact on a dink, with the reps in a strip and the replay bar.

    See

    Your rep stops at contact, with the ghost on your body. Up to three dots and one cue: the thing to fix first.

Questions

Good to know.

Which iPhone do I need?

An iPhone 12 or newer, on iOS 26. Everything runs on the phone, so a newer phone finishes sooner.

How should I film?

Put the phone on a tripod at hip height, 3–4 m (10–13 ft) away, side-on to you. Keep your whole body and the paddle in the picture for the whole set.

Film in the app, or import a clip you already have from Photos. 60 fps helps on drives.

What happens to my videos?

They stay on your phone, in Photos. Tracking and scoring run on the phone, offline too. No video is uploaded.

Only body points and your results back up to your account, so a new phone keeps your history. The privacy policy has the details.

Whose swing is the ghost?

Your own best rep, once you’ve filmed a few. Until then, a reference rep from an interim player, and the app says so on screen. A coach’s reference comes later, as an update.

Will it tell me my rating?

No. FormWatch looks at form, not results, and it doesn’t estimate a rating. It shows what your swing does and the one thing to fix first.

When can I get it?

FormWatch comes to the App Store for iPhone in December. Join the waitlist and we’ll write when it’s out. Android comes later.
