How it works
Three steps to a cleaner serve.
1
Film your serve
Record right in the app with the guided recorder, or import a clip from your camera roll — from the side or from behind.
2
Apexa reads it
On-device pose tracking finds each phase and measures your angles, tempo and contact — in seconds, without uploading a thing.
3
Fix one thing
Get your single highest-priority fault with a drill to practice it, then track the trend as it improves.
The one fix, first
See every phase. Get one thing to work on.
Every phase, detected automatically
Setup, toss, trophy, contact and follow-through — scored clean or fault.
Real numbers, not vibes
Tempo, reach and the joint angles behind each phase — plus an estimated racket-head speed to track over time.
One prioritized fix, plus a drill
We surface the single fault to fix next — with a drill to practice it.

Questions
Good to know.
Does my video leave my phone?+
No. Analysis runs entirely on your phone. Your clips are never uploaded and stay in your camera roll.
What does it actually measure?+
It detects each phase of the motion and reports the joint angles behind it — knee bend, shoulder tilt, trunk lean, arm extension at contact — plus your tempo, reach and an estimated racket-head speed.
What do I need to film a serve?+
Just your phone. Record right in the app with the guided recorder, or import a clip — filmed from the side or from behind. A single serve from one angle is enough to read. Imported clips need to be 60 fps or faster; the in-app recorder always is.
How accurate is it?+
It reads your body pose frame by frame to spot patterns and trends. Angles and tempo are measured; racket-head speed is a relative estimate — best for tracking your own progress, not a radar-accurate number. It's a practice tool, not a line-calling system.
What's free versus Pro?+
Free gives you 3 full analyses a month, keeps your last 10 serves, and includes every fault and drill — plus 14 days of Pro to start. Pro unlocks unlimited analyses, unlimited history and trends, reference-serve comparison, 120 fps slow-mo capture, watermark-free sharing, and removes ads.
Can I cancel anytime?+
Yes. Manage or cancel in the App Store — your free 14 days of Pro end on their own with no charge.
