Swing Sensei
AI Golf Swing Analyzer & Coach
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Drop strokes without expensive lessons. Swing Sensei scores your swing out of 10 and shows you exactly what to fix — in seconds, on your iPhone.
And with Live Range Mode, put your phone on a tripod at the driving range and get spoken feedback after every single swing — like having a coach standing behind you, for the price of a sleeve of balls.
Developed with Matt Montecucco, PGA — Junior Program Coordinator at Chambers Bay, host of the 2015 U.S. Open. Used by 60,000+ golfers. 100% on-device. No uploads. No internet required.
WHAT YOU GET
- Sensei Score out of 10, with detailed feedback on 11 checkpoints — from hip hinge at address to posture at impact
- Live Range Mode: real-time voice coaching at the range, every swing scored and saved automatically
- Cause-and-effect coaching that explains what's wrong, why it matters, and how to fix it
- A PGA-pro drill video for every major fault, filmed by Matt at Chambers Bay
- Your Week in Review every Sunday: your trend, your best swing, and the #1 thing to work on
- Per-checkpoint trend charts, slow-motion playback (0.25x / 0.5x / 1x), and still frames at all 6 swing phases
- Weekly streaks built for real golf schedules — one session a week keeps it alive
- Friends, leaderboards, and shareable score cards
- Full support for left-handed golfers
HOW IT WORKS

2. Sensei analyzes every checkpoint in seconds
3. Get your score and a personalized fix for your weakest area
WHY SWING SENSEI IS DIFFERENT
Most AI golf apps upload your video to a cloud server. Swing Sensei does everything on your phone with on-device AI:
- No uploads, ever — your video never leaves your device
- Works at the range, on the course, anywhere — no signal required
- Results in seconds
- Privacy by design: we never see your swings, your scores, or your data. We can't.
PRICING
Free: 3 swing analyses per month. Subscription and lifetime options in the app.
Stop guessing what's wrong with your swing. Start fixing it.

more Terrible app. Positions are totally wrong, not accurate in the slightest. Get advice from a real coach not this rubbish. People with horrible swings have scored far higher than pros and it’s generally just a terrible analysis
Developer Response Appreciate the feedback. The app scores a single swing on technical checkpoints, not overall ability — even pros get inconsistent scores on bad reps. We're constantly tuning the scoring. Would love to see your swing if you'd share it.

Swing Sensei also tells you exactly what it'll send before asking for notifications: one drill the day after your swing, and a reminder to film your next one. A cleaner start for new golfers, too. Bug fixes.

1.18 12 Aug
LIVE RANGE MODE IS HERE. Prop up your phone at the range and just swing — the app detects every swing automatically, scores it in seconds, and coaches you out loud between shots. No buttons, no tapping, no taking off your glove. Pick one thing to work on and hear yourself get better, swing by swing. Free users get one full teaser session; Premium unlocks unlimited range time.
Also in this release: grading got tougher. Yellow checkpoints now cost real points, so scores separate skill levels honestly — a tour swing still grades 9+, but "needs work" now reads like it. Your score may drop from previous versions; your swing didn't get worse, the grader got stricter. Plus smarter swing detection, more natural coach voice, and replay timing fixes.
1.17 10 Aug
Improved scoring accuracy, smarter coaching priorities, and plan improvements.
1.16.1 25 July
THE BIGGEST UPDATE WE'VE EVER SHIPPED. Every one of our 10 swing checks has been recalibrated against hundreds of TOUR-quality swings — and our new club detection reads your shaft position at every checkpoint of your swing, including mid-backswing positions we couldn't see before. Plus: cleaner coaching cards, more honest feedback when something can't be measured, and dozens of accuracy fixes throughout.
1.16 16 July
Your Sensei just got a memory
• Coaching that knows you — feedback now references YOUR history: improvements celebrated, recurring faults called out, and advice tied to the goal you picked.
• Weekly streaks — golf is a weekly game, so your streak now counts weeks of practice, not days. Every Saturday range session keeps it alive.
• Analyzing a friend's swing? Flip the new "someone else's swing" toggle and it won't touch your stats.
• Smarter notifications — max one per day, at the time you actually use the app, with a Sunday week-in-review. You can tune the frequency in Profile.
• A cleaner first-time experience and bug fixes throughout.
1.15 4 July

What's new in 1.4
Smarter scoring
Your Sensei Score is now smoother and fairer. Borderline checkpoints
no longer drag your number down by 2 points — the score reflects
exactly how close to ideal each part of your swing actually was.
Head Sway detection
New checkpoint: catches lateral head movement (the "sliding through
impact" fault) — a top amateur fault that vertical-only tracking misses.
Coaching panel on every drill
Watch a drill video and see exactly why it fixes your specific issue:
cause → consequence → fix, written by Matt Montecucco, PGA.
"How is this calculated?"
Tap the new pill under your score to see every checkpoint, color, and
weight that built your number. No more magic numbers.
Share your score
Tap Share Your Score to generate a beautiful animated video card with
your number, club, and swing breakdown — perfect for posting to
Instagram, TikTok, or sending to your coach.
Replay any swing
Open any swing from your Library and tap Replay Analysis to re-watch
it with the full overlay, frame-by-frame controls, and all your
checkpoints — exactly as it was the first time.
Faster + smoother
Quicker startup, smoother analysis on older iPhones, and several
edge-case crashes fixed.
Also in 1.4
• Tighter, more accurate head movement detection
• More forgiving lead knee scoring (no more wrong red flags for long hitters)
• Removed tempo from scoring (wasn't reliable enough at 30fps — drill moved to Extras)
• Library no longer shows blank for some users

Bug fixes.
