Apex Sports Coach
Measure your swing vs the pros
Free · Designed for iPad. Not verified for macOS.
They measure the ball. Apex measures your body. Upload one swing and get your Modern Tennis Score: five dimensions of technique, measured against pro reference data.
Every tennis app tells you what the ball did. Apex tells you what your body did — and exactly what to fix.
Apex is a technique measurement tool built on a real biomechanics engine. Record one swing with your phone, and Apex analyzes your body's movement frame by frame, then scores your mechanics against reference data from professional players.
THE MODERN TENNIS SCORE
One number out of 100 for your forehand, backhand, or serve — built from five measured dimensions of your technique:
- Preparation: unit turn and take-back timing
- Rotation: hip and shoulder drive through the swing
- Contact: where and how you meet the ball
- Balance: posture and stability through the stroke
- Recovery: how you reset for the next ball
It's a technique number the way a handicap is a golf number: portable, comparable, and trackable. Re-score the same stroke next month and see exactly which dimension moved.
SEE WHAT TO CHANGE
Apex analyzes your biomechanics frame by frame and shows you how to improve: where your body was at contact, which dimension cost you the most, and what a better version of that movement looks like, drawn over your own video.
COACHING THAT POINTS AT ONE THING
After each analysis, Apex identifies the highest-impact issue in your stroke and explains it in plain language — grounded in your measured numbers, not generic tips. Choose the coaching voice that suits you, from technical to encouraging.
TRACK YOUR CLIMB
Every analysis is saved. Watch your score trend by stroke and by dimension, climb the levels from Beginner to Elite, and earn badges for real mechanical milestones like Early Unit Turn and ATP Rotation.
SHARE THE NUMBER
Export a score card or a short clip and send it to your hitting partner, your coach, or the group chat — with your coach's one-line read on the swing attached. "My forehand: 72" starts a better conversation than "I think it's getting better."
WHAT APEX IS NOT
Apex is not a match tracker, a line caller, or a shot counter — other apps do that well. Apex is for practice: it measures your technique, shows you the gap, and tells you what to work on. It's the measurement layer between lessons, not a replacement for your coach.
HOW IT WORKS
1. Set up your phone with the guided capture wizard — any court, no extra hardware
2. Record a few swings
3. Get your Modern Tennis Score in minutes, with subscores and coaching
PRICING
Apex starts with 5 free credits. After that it is pay as you go: 1 credit analyzes a session and returns your five best strokes, 5 credits unlocks every stroke in that session, and 1 credit runs a premium AI analysis. Buy credits in packs of 5, 10 or 100, or take an unlimited pass for 30 days, 90 days or a year. Nothing auto-renews, and sharing is always free.
