How can we help?

Beta support · Usually within two business days

Email us: support@courtmuse.com. Include your iPhone model, iOS version, and what happened. A screen recording is the fastest way to show a problem.

Set up your first match

  1. Mount the phone. Fence mount or tripod behind the baseline, 5–8 feet high, both baselines and sidelines in frame. Do not zoom.
  2. Record or import. Use the app’s camera or import a video from Photos. A 1080p, 60 fps clip is ideal.
  3. Calibrate. Tap the four outer court corners in order: far left, far right, near right, near left. Use the numbered guide on screen.
  4. Analyze. Keep the app open while it runs. About 18 minutes for a 50-minute match.
  5. Review. Start with the rally list, then the court map and coaching cards. Export a reel if you want to post.

Common questions

Why does the analysis take so long?

CourtMuse runs on the iPhone’s own chip, with no cloud GPU. It processes about 0.36× the video length: roughly 4 minutes for a 10-minute set and 18 minutes for a 50-minute match. Keeping the app open and the phone cool helps.

Why is my video rotated or cropped?

Check that the phone is in portrait and mounted upright. If the video was recorded elsewhere, use the rotate control in the match toolbar before analysis. Recalibrate after rotating.

Why are the speeds different from a radar gun?

CourtMuse estimates speed from the video and shows the uncertainty. It is best for comparing your own sessions, not for absolute radar parity. Camera height, frame rate, and court calibration all affect the estimate.

Why does it say “close call”?

When the ball lands within the confidence band around a line, we show “close call” instead of a definitive call. CourtMuse is not an officiating system and should not be used to settle a dispute.

Does it upload my video?

No cloud upload. The analysis runs on the iPhone. Optional Mac sync sends the video to a Mac on your local network at an address you enter. See the privacy policy.

Can I use it on Android or Apple Watch?

Not in v1.0. CourtMuse is iPhone-only for now. Android is on the roadmap; there is no Watch app yet.

How do I delete a match?

Swipe the session in the Matches list and confirm. This removes the video and analysis from the app’s local storage. You can also delete all sessions in Settings.

Known limitations in the beta

  • The app must stay in the foreground while analysis runs in v1.0.
  • Stroke names and spin labels are best guesses on some footage.
  • Speeds and line calls are estimates, not radar or official line calling.
  • No Android, iPad-specific, or Apple Watch app.
  • Analysis quality depends on a stable mount, full court in frame, and good light.
