Stroke Gains

Leave the phone in the bag.

Track your shots on paper the way you always have. Photograph the card afterward and see the full strokes-gained breakdown, every category, every hole.

From a pencil line to a permanent record.

Three steps, in three places. Only pencil and paper come onto the course.

  1. On the course

    Track your shots the way you always have. Lie and distance in pencil, one line per shot. Nothing new to learn, nothing to carry.

  2. After the round

    Take one photo of the card. That’s the only thing the app ever asks of you.

    The scanner crops and straightens the card. This is the first time the phone comes out.

    Round results with the full scorecard, strokes gained per hole, and the category breakdown

    In the clubhouse

    Confirm anything the read wasn’t sure about, then see exactly where your strokes went, category by category, hole by hole.

Everything about your game. Nothing in the way of it.

Rich golf data has always asked for something in return: a sensor to wear, a screen to carry, or an evening spent typing in shots. Comprehensive meant intrusive. Stroke Gains splits that pair. Every finalized card becomes structured performance history, rounds, shots, outcomes, strokes gained, and trends, kept for as long as you play.

This is the system of record for your game. It organizes the evidence and leaves the conclusions to you.

The Insights approach view: strokes gained by distance and by starting lie across the last twenty rounds
Insights, the approach view. Strokes gained by distance and by starting lie, and a value is withheld whenever the sample is too thin to trust.

Then ask more of it.

The record is yours to question. Connect Stroke Gains to the assistant you already use, ChatGPT, Claude, or whatever earns your trust next, and put your own questions to your own shots. Your data drives the narrative, on a schedule you set.

No canned coaching, no diagnosis you didn’t ask for. The record answers when you ask.

Your assistant Monday, 7:02 AM

Every Monday morning, pull my Stroke Gains record and show me where I’m losing strokes and where this week’s practice time should go.

Read 20 rounds, 1,634 shots, strokes gained by category

Your biggest leak is approach play: −1.6 strokes per round over your last twenty, worst from 150 to 175 yards. Off the tee you’re gaining +0.3, so keep the driver plan.

Spend two of this week’s sessions on mid-iron distance control and keep one for lag putting. I’ll check the trend again next Monday.

Your assistant reads the record straight from Stroke Gains over MCP. None of this happens on the course.
Your assistant Tuesday, 6:45 AM

Every morning, check my calendar and pull each student’s Stroke Gains record before their lesson. Give me the state of their game since I last saw them, and what to dig into.

3 lessons today: Ben 10:00, Elena 2:00, Marcus 4:30

Read 5 new rounds across 3 shared records

Ben, 10:00. Two rounds since his last lesson, per round:

Off the tee +0.4 · Approach −2.1 · Around the green +0.2 · Putting −0.3

The approach slide is the story, worst from the rough. Start with iron contact.

Elena, 2:00. One round since her last lesson:

Off the tee +0.1 · Approach +0.3 · Around the green 0.0 · Putting +1.1

Putting is carrying her. Reinforce it, don’t rebuild it.

Marcus, 4:30, hasn’t logged a round since you last saw him.

Your calendar and the records your students choose to share, read together before the first lesson of the day.

For coaches

Walk into every lesson current.

Stroke Gains is built for the golfer first, but a record is made to be shared. When a student shares theirs with you, your assistant can prepare your day: who you’re seeing, what changed since the last lesson, where to look first.

No sensors on your students. No homework for them either. The rounds they already play become the notes you walk in with.

From the founder

I’ve spent my life trying to shoot lower scores, and the best players I know keep an honest record of their game. But I never wanted a sensor in my glove, a watch buzzing over a putt, or an hour of data entry waiting after the round. So I built the tool I wanted: a complete performance record from the paper card I already keep. The round stays the way it should be. The data is there when I want to ask more of it.
