Know what to do. See if it’s working.
SeamSight runs your practice in your ear, so you can keep your eyes on the ball, and tells you afterwards what moved.
No clipboard, no clock-watching.
- Each drill is announced, counted in with 3-2-1, timed, and followed by the next.
- Halfway and 10-second calls, on iPhone or Apple Watch.
- Your coach’s tip for the drill, on screen and spoken once as it starts.
- Music keeps playing; the calls dip it. On iOS 26 or later the phone can stay locked in your bag; on earlier versions a notification sounds at each drill change.
- The Lock Screen card shows the drill, its time, Pause and Skip.
Your week, pointed at your next tournament.
My Plan shows today’s practice, the next seven days and how many days to your next tournament, with the week of the build-up you’re in. Can’t make it? Cancel with a reason, and your coach sees why. Adjust a practice before you start it, and your coach sees that too.
What changes, practice to practice.
Shot accuracy
Film with SwingVision and every drill is scored on four levels: In, Direction, Depth and Target. Plus shots, Out and Net counts, and ball speed.
Heart rate and recovery
Heart rate across the practice with each drill marked, time in each of five zones, and how fast you recover in every rest.
How hard it felt
Rate each practice on the 0–10 effort scale coaches use. Results show the rating and the session load.
Practice together, in sync.
Each of you on your own iPhone or Watch. Schedule it ahead and connect at the court; a pause or skip on either moves both. One SwingVision file scores both of you.
Be your own coach.
Pick from the Practice Library, build your own workout, or let the Workout Generator put one together. The same week planner and reports a coach uses are yours. When you want help, Find a Coach lists coaches with their area and who they coach.
Just hitting? Track it anyway.
Free Play times a match or a hit with heart rate, no drills. Rate it after, like any practice.
Questions
Can I use SwingVision on the same iPhone?
Yes. Start SeamSight first, then SwingVision; the voice calls come through. SwingVision blacks out its screen while it records, so on that phone you get voice only. The best setup is to run the practice on your Apple Watch and let the phone film.
What if I don’t have an Apple Watch?
The iPhone runs the whole practice, and the Lock Screen shows the drill, its time, Pause and Skip. For heart rate, a Bluetooth chest strap or a watch that saves to Apple Health works.
Is there an Android version?
Not yet. SeamSight is for iPhone, with an optional Apple Watch app.
Does my partner need the app too?
To run the practice together, yes: each of you on your own iPhone or Watch, in sync. A pause or skip on either moves both.
