Why it works
The four things that make Coach by ATX different.
Every stats app can tell you what happened. These four pieces are what turn a log into a coaching relationship.
Voice-first, fully offline
Talk your round in. Never touch your screen.
Tap the mic, describe the shot the way you'd tell your buddy — club, lie, distance, where it missed. It fills in the scorecard. Works in a dead zone, syncs when you're back on Wi-Fi.
Real Strokes Gained
The same math the pros use — against the benchmark you pick.
Full Strokes Gained across Driving, Approach, Short Game, and Putting, measured against the level you're chasing: 10 handicap, 5, scratch, ladies scratch, men's tour, or ladies tour. Per round and per shot, color-coded so you can see where the strokes went.
One coach, always with you
A voice coach that remembers every round and actually talks to you.
Coach by ATX keeps a running memory of your game — your patterns, your last process goal, whether you followed through — and has it open during a real back-and-forth voice conversation. Set your next reminder before you hang up.
WHS-formula handicap + granular putting
The exact WHS math, plus putting stats that actually diagnose three-putts.
Same formula as an official index — 8-of-20, score differentials, net double bogey cap, all of it. Not an official GHIN number (that requires club membership), but the math is identical. Plus first-putt proximity, three-putt rate by distance, and lag-pressure trends most apps never surface.
Round Recording
Voice-first, offline, and forgiving
Logging a round should not pull you out of it. Coach by ATX runs completely offline, captures shots by voice in seconds, and lets you fix your own mistakes after the fact.
- Describe the shot in plain English — club, lie, distance, miss — and it fills in the card
- Works with no signal on the course; everything syncs when you're back on Wi-Fi
- Pick how much you want to track: Quick, More, or All — only the fields you care about
- Add voice notes to any shot — record, trim, delete, play back later
- Glance at your lock screen for live round progress
- 40,000+ courses loaded automatically with pars, yardages, tee ratings, and slope
- Front or back tee selection with correct course rating and slope
- Shotgun starts and partial rounds — start on any hole
- If the shot count doesn't match what you said, it asks — instead of guessing
- "Actually on hole 5 I meant…" — it fixes earlier holes for you
- One voice note can fill multiple missing shots at once
- Full penalty handling: OB, lost ball, penalty area, unplayable — no math on your part
Round Review & Editing
Fix anything, in seconds
Every shot lands in a visual review screen. Green cards are complete, amber need a detail, red need another look. Edit anything by hand, or have the app re-read your voice note.
- Per-shot cards that flag exactly what's missing (green / amber / red)
- Change lie, distance, club, or miss direction on any shot
- Add or delete shots with a simple position picker
- Add an entire missing hole by voice
- Missing-field warnings you can fix in one tap
- Catches obviously wrong distances so you don't post a 380-yard 9-iron
Rounds History
Every round, filterable, permanent
In-progress and completed rounds side by side, filterable by format, date, course, or tournament.
- Chronological list with in-progress and completed sections
- Filter 9 / 18 / other with one tap
- Advanced filters: date range, course, tournament
- Round detail view with a hole-by-hole breakdown
- Delete with a confirmation — no accidental loss
Strokes Gained
The same framework the tour uses
Four SG categories, six benchmarks, per round and per shot. Includes recovery shots, which most apps skip entirely.
- Driving, Approach, Short Game, and Putting — all four
- Compare against 10 hcp, 5 hcp, scratch, ladies scratch, men's tour, or ladies tour
- Per round and per shot, color-coded green (gained) and red (lost)
- Recovery-shot category so a punch-out isn't scored like an approach
- Switch benchmarks or units and every number recalculates instantly
- Reference numbers for every lie type and distance so you can trust the math
Stats Dashboard
The numbers that change what you practice
Not just totals — dispersion, heatmaps, distance bands, and the specific putting patterns that cause three-putts.
- Overview: overall SG, scoring breakdown, best and worst shots of the round
- Driving: top-75% drive distance, fairways hit, club dispersion
- Approach: GIR %, par-3 GIR, par-5 hit-in-two, proximity by distance band
- Short Game: scrambling %, proximity from around the green, sand-save %
- Putting: putts per GIR, three-putt rate, make % by distance, directional-miss grid, Green Zone heatmaps
- Scoring and SG trends over time
- Club distance chart showing your real gaps
- Filter by last round, last 3 / 5 / 10, or all-time — plus format, date, course, tournament
WHS Handicap Estimate
Your handicap, calculated the WHS way — not an official GHIN index
Coach by ATX runs the same formula an official index uses. It's not a GHIN number (that requires club membership), but it's WHS-accurate and it updates automatically after every round you log.
- Adjusted gross score with net double bogey cap
- Score differential with the sliding scale for 3–20 rounds
- Soft cap and hard cap applied automatically
- See exactly which rounds are counting toward your index
- Starts with a realistic sample so you're not staring at a blank number
- In-app explainer that walks through the formula in plain English

Pattern Analysis
The parts of your game we can measure exactly
Some patterns aren't a guess — they're just math on the shots you logged. Coach by ATX works those out ahead of time so every coaching conversation is grounded in what actually happened.
- Round-to-round patterns computed from your real shots
- A shared vocabulary for shot causes so "pull hook" always means the same thing
- Front-6 / mid-6 / back-6 splits — where do you fall apart?
- Practice plans generated from the patterns we found
Reminders & Emails
The follow-through most apps forget
The process goal only works if you remember it before the next round. Coach by ATX pushes it to your phone, and sends you a real round summary you'll actually read.
- Schedule process-goal reminders before your next round
- The coach can set a reminder for you live during a voice conversation
- Push notifications at the date and time you pick
- Upcoming and past reminders — reschedule or delete anytime
- Round-summary email: scorecard, SG stats, and top 5 best/worst shots, sent ~10 minutes after the round so you can still tweak it
- Getting-started welcome email so you're not lost on day one
- Optional weekly digest of how your game is trending

Frequently asked
Is Coach by ATX iPhone-only?+
Yes. Coach by ATX is iPhone-only right now. The voice logging, offline play, live coaching, and background sync are all built natively for iOS — Android is not on the near-term roadmap.
Does it really work with no signal on the course?+
Yes. Play a full round in a dead zone and lose nothing. Everything you need is already on your phone, and every shot you log queues up locally. The moment you're back on Wi-Fi, it syncs — no duplicates, no lost holes.
Is the WHS handicap calculation official?+
No — official WHS indexes require membership at a USGA-affiliated club or course. Coach by ATX uses the exact same formula (adjusted gross score with net double bogey cap, score differentials, 8-of-20 rule, soft and hard caps), so the math is identical, but the number is not usable in sanctioned competition.
Does the live voice coach actually help, or is it a gimmick?+
It has your Strokes Gained and your patterns open in front of it while you talk. So it talks about your game, not golf in general. Ask why you keep missing greens right, and it will tell you — from your own numbers. The Root Cause Session mode is built specifically around your worst shots.
Can I cancel and delete my data whenever I want?+
Yes. Cancel any time from iPhone subscription settings — cancellation takes effect at the end of the current billing period. From inside the app, Delete Account removes all of your data.
How long does logging a shot actually take?+
About ten seconds per hole in total. Tap the mic, describe the shots the way you'd tell a friend, and Coach by ATX handles the rest. If you don't want the full detail on a given hole, switch to a lighter tracking tier (Quick / More / All) and capture less.

14 days free. No card required. iPhone only. If Coach by ATX doesn't help you find the one thing to work on, walk away — nothing renews.
We'll email you at launch.
