Better data always means better golf.
Feel lies. The golf ball is a big fat liar. So we built the honest version: a family of tools that tell you what your round actually said, what the tour data actually shows, and what to do about it on Saturday.

Golfers spend fortunes rehearsing swings and zero minutes rehearsing decisions.
Never a bare number. Every stat gets a fraction, a comparison, or a "here's what that actually means." The tour average is the honest yardstick, and it's kinder than you think.
DataGolf, Slash Golf, the USGA Stimpmeter booklet, Penner, Pelz, Holmes, Broadie's ShotLink research. No invented statistics anywhere in the family: if a number changes, we find the source first.
We grade the decision, never the luck. Stats exist to give you permission to commit, not to judge you for a Saturday.
Five apps. One idea.
Each one takes a different piece of the game: your rounds, the pros, your strategy, your putting, and your nerve, and hands it back to you as something you can actually use.
Log a round in a few taps, then get your gaps ranked by strokes actually lost, in-round caddie nudges built from your own miss patterns, tee advice anchored to pro data, and a "Prove It" loop that checks whether the practice worked.
Tour statistics turned into plain-English stories. Game Shape profiles, head-to-head compares, and cards worth screenshotting.
A decision range. You never swing: you read the hole, pick a line blind, and get graded on the choice.
Slope, stimp, moisture, grain, wind, capture speed: on a 3D green you can experiment on. Every constant traces to a citation.
Arcade golf where you sprint after every shot and a visible storm wall chases you down the hole. The fun one, and the one that trains your nerve.
Your round, translated into your next practice session.
Most apps tell you what you shot. This one tells you where the strokes went, which gap is costing you the most, and exactly which drill closes it, then checks back in to see if it worked.
- 01Gaps ranked by strokes lost, quantified, never "leaks"
- 02Caddie pass: in-round nudges from your own miss patterns
- 03Tee Reality: tee advice anchored to real pro approach distances
- 04A 30-drill library and a session builder that targets your worst gap
- 05Course memory, personal par, and a game plan that remembers
Free to use. Data Action Pro is an optional subscription that unlocks the guided practice and deeper insight layer. Your rounds stay on your device.




Golf has one of the richest statistical records in sport. Fans mostly meet it as a stale table.
Golf Matters is explanation as entertainment: tour statistics turned into stories a golf fan actually wants to read. Fast, visual, and built to settle an argument.
A five-axis signature: distance, fairways, approach, short game, putting, built from strokes-gained percentiles.
Every number arrives with a percentile, a delta, or a tier. The "so what" is the point.
A multi-year read on what this week's venue has actually rewarded. Usually not the thing on TV.
The tour pro whose game most resembles yours. It's more flattering than you'd think.
No betting framing anywhere: "The Call" is a plain winner's pick for bragging rights. Data credited to DataGolf and Slash Golf on every card.
A driving range for decisions.
You never swing a club in Course IQ. Every hole gives you two to four real options; the engine knows each one's true expected value from your own landing area and the hole's geometry. You read the hole and pick blind, then the reveal shows the odds each line really carried, and grades the decision, never the luck.
- →The Daily Hole: one fresh hole a day, the same hole for everyone
- →Scenario drills: protect a lead, chase a number, play the pressure
- →Wind is a visible variable, never hidden randomness
- →Imports your real distances and miss pattern from Data Action Golf




The science behind why a putt moves the way it does, not just that it did.
An interactive physics lab with a green you can experiment on. Change the stimp. Add moisture. Turn the grain. Watch what actually happens, then earn a grade on your read, because the roll here is deterministic, so there's no luck to blame.
Every physics constant traces to a cited source: Penner (2002), the USGA Stimpmeter booklet, Pelz (2000), Holmes (1991). Seven short lessons in The Physics of Putting, plus graded drills and a certified course. Runs entirely on your phone: no network, no accounts.
The storm is the pressure, and this is the only range where you can practice it.
Arcade golf with Mario Kart energy: you sprint after every shot while a visible storm wall chases you down the hole. Time your strike, manage stamina, spend a Stormgrip, and get to the ball before the weather gets to you. It's the third leg of the trilogy: Course IQ trains the decision, Putting IQ trains the physics, Tempest trains the nerve.
- →Daily Hazard event with a real reward loop and a countdown
- →Two venues, Tempest Ridge and Coastal Fury, across five difficulty tiers
- →Locker with gear, a trail caddy, and three upgrade tracks
- →A Pressure Profile that scores how you swing calm versus clutch

185 episodes of asking the golf question nobody asks.
It launched as Data Axis Golf, and nobody knew what axis meant. Same show, same host, clearer name: Data Action Golf. A stat, a fraction, a comparison, and permission to relax about your own game. Then: let's tee it up.
The full 185-episode archive from the original run is up now. The show is coming back as Data Monday: a weekly look at how the winner actually won, and what it adds to our understanding of what matters most in golf. The research behind it is already on the blog, one article per tournament.

How the winner actually won.
One article per PGA TOUR tournament, built from the Data Monday research: the four strokes-gained categories, the scorecard, the winning formula, and what it means for your Saturday. Every number sourced to DataGolf.
Your best round, on the wall.
Everybody remembers the day it all worked. Data Action Golf hands the round you already logged straight to Best Day Prints: the card, the hole-by-hole, the one shot you'll describe for the next decade, and turns it into something framed.
The round itself: scorecard, hole-by-hole, and the story of the day, laid out to be looked at.
Routing art for the course you played, drawn from open map data and printed clean.
Two owner-approved designs, Heritage and Gallery, for events, clubs and one-off days.
Partnerships, press, or a stat you want us to settle.
Courses, coaches, data partners, podcast guests, and listeners with a good argument: all welcome. Tell us what you've got.
