Great ideas — for a body that isn't yours. They've never seen you play, and they never check back.

It's a loop.

EVERY WAY PLAYERS TRY TO IMPROVE
Each one gives you a piece. Apex gives you the loop.
Stats & shot maps
Your matches, beautifully counted. But stats are the outcome — they can't show you the stroke that produces them.
Clinics & repetition
Reps build habits — including the ones you already have. Practice without measurement grooves today's stroke, whatever it is.
A coach, alone
Real judgment and a trained eye — for one hour a week, with feel and memory carrying the other six days.
BETTER THAN A COACH ALONE
The best coach in the world sees one hour of your week.
Your habits form unwatched
Lessons are one hour. Your forehand is built in the other five sessions, with nobody watching. Apex is on court every time you are.
"Better" isn't a number
Human feedback runs on feel and memory. Apex turns every cue into a measurement that moves or doesn't — the same yardstick, every session.
Did the fix actually stick?
The hardest question in coaching, answered with a re-measurement instead of a shrug. When it sticks, you move on. When it doesn't, you know that too.
This is not an argument against coaches — it's the argument coaches win with. Your coach brings judgment. Apex brings measurement. Together, the loop closes every session instead of once a week.
THE LOOP, IN PRACTICE
Record. Analyze. Practice. Reanalyze.
Record using the Apex app
Set up your phone, hit record, and play. The Apex app captures your whole session in high-speed video — nothing to buy, nothing to wear, nothing to remember mid-rally.
Detailed video stroke analysis
Every stroke measured frame by frame. Apex shows you your biggest opportunity to improve — an earlier unit turn, contact out in front — in plain words, with an explainer, on your own footage. Not a guess. A picture.
Practice the improvement
Drills matched to that improvement and to your plan — your time, your body, your goals. Never a laundry list. The one change worth making first.
Reanalyze, and move on
Record your next session and Apex reads the same thing with the same versioned yardstick — a straight answer on whether the change stuck. When it does, the goal retires and your next opportunity takes its place.
NO VIBES
Every claim comes with a number attached.

ILLUSTRATIVE UI — YOUR NUMBERS COME FROM YOUR VIDEO.
Your body, measured against reference bands from actual ATP/WTA strokes — and honest by construction. Advice only ever comes from what the video shows. Bad footage gets flagged, not graded, and costs you nothing. If we can't see it, we won't say it.
OPTIONAL, BY DESIGN
Already have a coach? Bring them.
Your coach sees the same measurements you do, and can deliver lessons and feedback right through the app — so what they teach on Tuesday gets measured on Thursday. Apex between lessons, your coach on top of it. Their judgment finally gets instruments.
Your skeleton over Alcaraz's
Frame-aligned on your own video. When your coach says your unit turn is late, watch exactly what "on time" looks like — in your own points. More pros over time.
Uploaded once, understood forever
Apex keeps the full motion data from every session. As the engine improves, your entire history re-measures automatically — your record gets sharper over time without re-uploading a thing.
It knows who's who
Record the whole hit. Apex spots which swings are your partner's, and — with your say-so — sends them their swings by text. They join free. Recognition is opt-in for everyone, private to your account.
PAY FOR TENNIS, NOT FOR MONTHS
Credits, not a subscription.
A subscription bills you for the weeks it rained. Apex charges for what it analyzes — nothing else.
One credit, one session
A full hitting session analyzed — stroke analysis, score, drills, reassessment. All of it.
Packs, not plans
Buy more at once, pay less per session. No tiers to decode.
Credits never spoil
Take December off. They'll be there in March, worth exactly what you paid.
Unscoreable costs nothing
If we can't find tennis in your footage, you're not charged — automatically.
Not a coach replacement. Not match stats. Apex is the loop between your lessons — the way runners own their pace and golfers own their handicap, you own your technique.
STRAIGHT ANSWERS
What you're probably wondering.
Do I need special gear?
No. A phone and somewhere to lean it. A cheap tripod helps; nothing else required.
What level is it for?
The reference bands are professional; the coaching meets you where you are. The measurement shows the gap — your coach picks the part of it you can close this month.
Is this a chatbot?
It talks, but it doesn't improvise. Every piece of advice traces to a measurement from your own video — if the data isn't there, it says so instead of guessing.
Can my coach use it?
Yes — that's the point. Coaches see your measurements and deliver lessons and feedback through the app. Apex makes their coaching measurable, not replaceable.
Your coach should know you first.
Tell it your goals, your time, your body — then film a session and take your first trip around the loop.
