Hole 10 · 428 yds · Par 4

It knows your game

Theory knows your game. And it goes where you go.

Every round you log teaches Theory more about you: what you do well, where your strokes go, and the clubs in your bag. That knowledge comes with you to every course you play.

Around your game
Most common miss off the tee Over draw — 48% of your misses The over draw is your #1 miss off the tee — 48% of your shape misses, usually finishing left, rough.
Most common miss into greens Over draw — 19% of measured approaches The over draw is your #1 miss into greens — 19% of measured approaches, −0.35 a shot.
Up and down 31% of 48 chances A chip that finishes 10+ ft away sits on 39% of your bogey-or-worse holes but only 8% of your pars — and your conversion collapses from 58% inside 10 feet to 12% beyond it. Pick the landing spot that gets the ball inside 10 feet — not the one that chases the pin.
The putting drain 6–10 ft: 26% made, −0.31 a putt 6–10 ft is your biggest putting drain: 26% made across 27 putts, −0.31 a putt. That range is where putting practice actually pays you.
The bogey maker A penalty — on 26% of bogeys vs 0% of pars The single biggest difference between your pars and your bogeys: a penalty — it shows up almost never on a par hole.

Your strengths

What you can lean on when it counts.

“You don't spiral after a double — you bounce back.”

Your weaknesses

Where your strokes actually go, ranked, so you know what's worth the work and what isn't.

Any course

Open a course you've never played and every hole is planned for your clubs, before you get there.

Measured against your tour

Women are compared with LPGA Tour players and with women at the same handicap. Men with PGA Tour players and with men at the same handicap. Same app, the right yardstick for your game.

Theory shows you what's holding you back.

After a few rounds, Theory shows you everything holding your game back and everything that's working for you, in the order it matters, in plain English, with the shots that prove it. Then ask it anything about your game and get an answer from your own rounds.

How it works

One loop. Every round feeds the next.

You play, Theory watches, and you always know what's worth your practice time.

Why golfers trust it

A coach that knows what it doesn't know.

Only your rounds

Every read comes from shots you played. Nothing generic, nothing borrowed from someone else's game.

Says when it's too soon

With only a round or two in, Theory tells you it's still counting, rather than inventing a verdict.

In the order it matters

Everything holding you back, ranked by what it costs you, so your practice time goes where the strokes are.

For tournament golfers

Playing for something? Bring it to the event.

Club championships, qualifiers, high school and college events. Your competition rounds belong in the same plan as every other round.

Plan the course before

Walk every hole the night before: three ways to play each one, priced from your own clubs.

Play within the rules

Turn on tournament mode and, during the round, the app shows only what the Rules of Golf allow.

Learn from it after

When you finish, the round gets the same full breakdown as any other, and it counts toward your goal.
