You've hit thousands of balls. But are you actually getting better?

Sound familiar?
Every ball you hit without feedback might be making your swing worse. You can't feel what you can't see.
That last swing felt different. Better, maybe? But you have no idea what you actually did. The feel fades before you can repeat it.
You leave the lesson confident. A week later, the cues are gone. Your pro isn't at the range with you. You're back to guessing.
Arc watches every swing and tells you exactly what to focus on next.
Other apps drown you in data. Launch angles. Spin rates. Club paths. Numbers that mean nothing when you're standing over the ball.
"Focus on keeping your lead shoulder down through impact."
Arc speaks your cue before you hit the next ball. No stopping to check your phone. No scrubbing through video. Stay in the zone.
"That's better. Now try the same thing with a 7-iron."
Arc tracks which cues actually work for YOUR swing across sessions. It knows that "shorter backswing" improved your contact 23% last month.
"This cue worked for you before. Let's try it again."
Old habits creeping back? Arc notices before you do. It'll flag regressions and suggest the fix that worked last time.
"Early extension is back. Remember: sit into impact."
No sensors. No extra gear. Just your iPhone.
Use a simple tripod, lean it against your bag, or set it on a bench. Arc will tell you if the angle needs adjusting.
Arc detects each swing automatically. No buttons to press. No recordings to start. Just practice.
Between swings, Arc tells you what to focus on. One clear thought. Then swing again.
Everything runs on your iPhone. No cloud. No lag. No subscriptions to forget.
Arc uses audio, motion, and camera together to detect real swings. No buttons. No false triggers.
Sub-second feedback with no internet required. Works at any range, indoor or outdoor.
Scrub through your swing with pose overlay. See exactly what your body did at impact.
Start and stop sessions hands-free. Add notes to swings without touching your phone.
Track tempo, consistency, and contact quality across sessions. See what's actually improving.
AI-powered summaries after each session. Key insights and recommended focus areas.
Arc notices when your swing breaks down from tiredness. Quality over quantity.
Separate insights for each club in your bag. See where your game really needs work.
Arc uses ARKit to measure what radar misses: your body, your setup, and your intent.
Ball position relative to stance, shoulder alignment, shaft lean, spine tilt. TrackMan measures the ball. Arc measures you before impact.
Tap the flag to set your target. Arc measures face alignment, body alignment, and launch direction relative to your intent—not just an arbitrary axis.
Not just "push" or "pull." Get start line bias, lateral dispersion in yards, ellipse confidence area, and club-specific heatmaps. Track improvement: "Your 7-iron dispersion tightened 22%."
Combine club path, face orientation, and start direction to infer heel/toe strike patterns. Different signal source than radar's signature inference.
For chipping: detect landing zones, build dispersion ellipses, gamify improvement. "Land 5 balls inside 1m circle." TrackMan shows numbers. Arc creates games.
Stance width consistency, ball position drift, shoulder alignment trends. You're not analyzing swings—you're analyzing patterns of intent over time.
Build real shot dispersion maps in world space. Detect aim drift, stance creeping, left/right patterns relative to the flag. Radar can't see stance creep.
Map swings chronologically. Does dispersion widen after 35 balls? Does launch angle drop? "You fade more when tired." No single-swing app can tell that.
Group shots into patterns: push fades, pull hooks, straight clusters. "You have two swing patterns competing." That's high-level coaching insight.
From launch yaw, angle, and estimated carry, model start direction, predicted apex, and landing ellipse. "Likely slight fade" without full ball tracking.
Define 10-yard corridors, 5-yard dispersion goals, randomized targets. Gamify practice: "Hit 5 shots within 8 yards of target." That's addictive improvement.
Track median carry by club, distance overlap, gap compression. "Your 6i and 7i overlap by 11 yards." Pro-level insight from a phone.
LiDAR detects green slope, uphill/downhill lies, ball above/below feet. TrackMan ignores lie geometry. Arc measures it and adjusts coaching.
Radar needs range space. Arc works indoors, backyard, garage net. Simulate carry from launch vector + club model. Pocket launch monitor with spatial coaching.
Overlay previous swings in the same space. Compare address positions in meters. TrackMan gives numbers. Arc gives spatial comparison you can see.
Not "Your swing was steep." Instead: "Your dispersion moved right after you widened stance. When you narrowed it, dispersion tightened and start line improved." That's storytelling.
"I've tried every swing app. They all give me 47 metrics I don't understand. Arc just tells me what to do next. Finally."
"My coach gave me 3 things to work on. I forgot them all by Tuesday. Now Arc reminds me, every swing, exactly what to focus on."
"I used to hit 100 balls and hope for the best. Now I hit 50 and actually improve. Arc told me when I was getting tired and my swing was breaking down."
One lesson costs $150. Arc costs less than one range session per month.
Try it out. See if it clicks.
For golfers who practice weekly.
For serious improvement.
Most apps give you data: launch angle, swing speed, club path. Great for Tour pros with coaches to interpret it. Arc gives you one actionable cue you can use immediately. No analysis paralysis.
Just your iPhone (iPhone 12 or newer). No sensors, no wearables, no launch monitor. A simple tripod helps but isn't required.
Arc works anywhere: outdoor ranges, indoor simulators, even your backyard. It runs on-device so you don't need WiFi or cell service.
Nope. Arc reinforces what your coach teaches. It's like having your coach whisper a reminder before each swing. You can also customize the cues to match your coach's terminology.
