Data Action Golf
Data Action 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.
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.
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.
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.
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 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.
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 dispersion cone 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.
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.
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.
Built for iPhone and Android from a shared gameplay contract. Fully offline — no network required.
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.
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.
Courses, coaches, data partners, podcast guests, and listeners with a good argument — all welcome. Tell us what you've got.
