The 90-minute problem
You film the match.
Then you spend an hour editing it.
Scrubbing a two-hour video to find eight points is not practice. It is homework. CourtMuse does the first pass for you.
The usual way
- Scrub the timeline to find the rallies
- Guess the speed from the video
- Lose the line calls you wanted to check
- Export, crop, caption, post
45–90 minutes per match
With CourtMuse
- Every rally cut automatically
- Estimated shot speeds and placement
- A bounce map and close-call chips
- A reel ready for Reels, TikTok, or Shorts
About 18 minutes for a 50-minute match
Three things you get
Watchable. Measurable. Private.
See what you actually did
Estimated shot speed, landing position, IN/OUT with a close-call band, and a bounce map. Not a guess from the eye — a measured estimate with the uncertainty shown.
Speeds · bounce map · close calls
On your phone. Not the cloud.
The analysis runs on the iPhone. Your video is not uploaded to a CourtMuse server, and there is no minutes meter. Optional Mac sync stays on your local network.
On-device · no credits · your footage
How it works
Mount. Play. Review.
01
Mount your phone
Fence mount or tripod, behind the baseline, five to eight feet up. Both baselines and sidelines in frame. No zoom.
02
Record or import
Film live from the app, or import a video you already shot. Tap the four court corners once and CourtMuse remembers the setup.
03
Analyze while you cool down
About 18 minutes for a 50-minute match. Then review the rallies, speeds, court map, and coaching cards — and post the points worth posting.
What you need: an iPhone on iOS 17 or later, a fence mount or tripod, and a full court in frame. No subscription, no cloud account, no upload.
A closer look
The match. The map. The coaching.
A preview of the three screens you will use most. Illustrative UI; real screenshots arrive with the beta.
Every rally, ranked
No scrubbing. The points are already cut, ordered, and ready to review.
See your court
Every bounce, mapped. Tap a landing point to jump straight to the shot.
Know what to fix
One clear read and one drill, based on what actually happened in your match.
Product preview — illustrative. Real screenshots will use owner-filmed footage, not broadcast or watermarked clips.
The honest details
What CourtMuse is — and what it is not.
Tennis data is easy to over-claim. Here is the line we hold.
Speed
Estimated, not radar. CourtMuse measures from the video and shows the uncertainty. Use it to compare your own sessions, not to win a bar bet.
Line calls
A close-call chip, not an official call. When the margin is inside the confidence band, we say “close call” instead of pretending to be Hawk-Eye.
Analysis time
About 0.36× the video length. A 10-minute set takes about 4 minutes; a 50-minute match takes about 18. The app needs to stay open while it runs in v1.0.
Coaching
A coach’s read, not a replacement. CourtMuse surfaces patterns and drills from your match. It does not see your grip, your fitness, or your opponent’s tendencies.
Privacy
On-device by default. No cloud upload, no credits, no account. Optional Mac sync sends the video to a Mac on your local network, at an address you enter.
Availability
iPhone first. iOS 17+, portrait. Android is on the roadmap; there is no Apple Watch app in v1.0.
December beta
Be first on court.
Join the beta list for early access, setup tips, and the launch date. We will only email you about CourtMuse.
Free during the beta. Pro is planned as a one-time purchase — not a subscription.
Questions
Before you ask.
Do I need a special camera or mount?
No. Any recent iPhone works. A fence mount or tripod behind the baseline is enough. The app includes an alignment guide and a four-corner calibration.
Does CourtMuse upload my video?
No cloud upload. The analysis runs on the iPhone. If you choose Mac sync, the video goes to a Mac on your local network at an address you enter. We do not receive it.
How accurate are the speeds and line calls?
They are estimates from the video, with uncertainty shown. Speeds are best for comparing your own sessions. Line calls use a close-call band; they are not official officiating and should not be used to settle a dispute.
How long does analysis take?
About 0.36× the video length: roughly 4 minutes for a 10-minute set and 18 minutes for a 50-minute match. The app needs to stay open while it runs in v1.0.
Is there an Android or Apple Watch app?
Not in v1.0. CourtMuse is iPhone-only for now. Android is on the roadmap; there is no Watch app yet.
What will it cost?
Free during the beta. Pro is planned as a one-time purchase, not a subscription. There are no per-match credits.
