SwingDiff vs JaMaGolf

See what's off in your swing — through your own skeleton. SwingDiff analyzes your golf swing video on-device, then overlays your skeleton against a reference swing or one of your past swings so you can diff (compare) your way to a more repeatable swing. ON-DEVICE SKELETON ANALYSIS Skeleton extraction with Vision Framework. Address, Top, Impact, and Follow-through are auto-detected as the four key phases — no manual frame scrubbing. 15-POINT AUTO DIAGNOSIS Spine tilt, axis lean at the top, hand position at impact — 15 repeatability-critical points are graded pass / fail with a clear overall score, so you know exactly what to work on next. DIFF (COMPARE) VS. REFERENCE OR PAST SELF Overlay your skeleton on a built-in reference swing, or on a previously analyzed swing of your own. Phase by phase you can see where you drift — and that's where repeatability comes from. PROGRESS TRACKING Every analysis is saved to your history. Watch your score trend over time to see whether your practice is paying off. iPhone Slo-Mo videos (120fps / 240fps) are fully supported. PRIVACY-FIRST Videos, images, and skeleton data never leave your iPhone. No account, no sign-in. Every feature works offline. SWINGDIFF PRO • Monthly / Yearly / Lifetime tiers • Ad-free — no ad before each analysis • No home-screen banner ads Subscriptions are charged to your Apple ID at confirmation of purchase and auto-renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel from iOS Settings ＞ your Apple ID ＞ Subscriptions. HOW TO SHOOT Record Down-the-Line (DTL) — directly behind your ball flight line — with your phone held vertically. Position the camera so you appear on the left and the ball on the right of the frame. Bright outdoor light, a simple background, and enough distance to capture your full body all help detection accuracy. LEFT-HANDED SUPPORT Right- and left-handed swings are both supported. Choose your dominant hand during onboarding or in Settings, and left-handed swings are analyzed and compared just like right-handed ones.

JaMaGolf is your personal golf coach – with you on the range and at home. VIDEO SWING ANALYSIS Record a swing or import a video. JaMaGolf detects your body pose on-device, segments the swing into phases (setup, backswing, top, downswing, impact, follow-through) and measures tempo, spine tilt, head movement and more. An AI coach explains clearly what worked and what to practice next – with concrete drills. LIVE COACHING ON THE RANGE Prop your iPhone up 3–4 meters away and just hit balls. The app detects every swing automatically, analyzes it and speaks a short tip right away – like a real coach standing next to you. The coach remembers your recent swings and never repeats itself. YOUR PROGRESS Every swing lands in your history – with video or skeleton playback, phase timeline and swing metrics. Progress charts show whether you are improving: today, this week, this month. YOUR DATA STAYS YOURS Videos never leave your iPhone. For coaching tips, only derived metrics and a few downscaled frames are sent encrypted to our EU server and never stored. No accounts, no tracking, no ads. FEATURES • Video swing analysis with skeleton overlay • Live range mode with spoken tips (English & German) • Club selection – the coach judges a driver differently from a wedge • Phase timeline & swing metrics (tempo, head movement and more) • Progress charts across days, weeks and months • Weekly tour news • Fully localized in English and German THE FOCUS LOOP After three swings the coach picks exactly ONE thing for the session — quiet head, tempo, long lead arm or posture — and only speaks when it matters. You get a concrete drill to go with it. Next visit, the first swings re-measure whether it stuck: "4 of 5 in the green, before 2 of 6."
