Strike Lab Golf Swing Analyzer vs Strobe

You're not short on practice. You're practicing the wrong thing. Strike Lab measures your ball with your phone, finds the one thing behind your miss, and gives you one drill. Then it checks in, and you film again to see what moved. LAUNCH DATA, INCLUDED Film 10 shots from behind the ball. Your phone measures each ball's start line, launch angle and ball speed, and estimates the carry. No launch monitor needed. Then Strike Lab compares your worst swings with your straightest, so the fix comes from your own misses. ONE THING, NOT TEN No dashboard. One decision. When your swings share one fault, Strike Lab names it, shows you the frame where it happens, and gives you one drill. Each drill has a ball test to pass next time. When your swings share no fault, it says so. IT REMEMBERS Your swings stay in your history until you delete them. After you start a drill, Strike Lab checks in on days 3, 7 and 12: Did it, Not yet, or Show me again. After three drill sessions, film 10 more shots and see what moved. NO RANGE TODAY? Pick a swing already on your phone and get a quick read now. Film 10 shots at your next practice. WHAT YOU NEED An iPhone with iOS 18 or later. For 10 shots, add a tripod, daylight, and a net or a range. Setup takes four steps on one screen. The app checks the light, the sun, whether your phone is level, the ball and the target, and tells you what to fix. WE SAY WHEN WE CAN'T SEE If Strike Lab can't see your swing or your ball, it says so and shows you how to film again. It measures start line, launch and ball speed. It does not measure spin, club path or curve, and a net hides the curve. We have no accuracy number yet, so the app replays each shot and draws where the ball started, on your own footage. Check it yourself. IS IT A COACH? No. It is the read between lessons, and the check-in when your coach has gone home. Bring your fix to your next lesson. WHAT IT COSTS Nothing right now. Strike Lab is free during early access, and there is nothing to buy in the app. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.strikelabhq.com/privacy.html

Record your swing at up to 240 frames per second, then step through it one frame at a time. CAPTURE • Up to 240fps on supported iPhones — a driver swing spread across hundreds of frames • Start and stop from your Apple Watch, so the phone can stay on the bag • Instant replay the moment a swing lands • Import swings you already shot at original quality — no re-compression, no lost frames — and trim a long clip down on the way in ANALYZE • Automatic body tracking — the skeleton follows you through the whole swing, with nothing to place by hand • Show only the parts you're looking at: head, spine, shoulders, arms, hands, hips, legs • Nine checkpoints found for you — address, takeaway, backswing, top, downswing, delivery, impact, follow-through, finish — on a phase bar under the scrubber. Tap one to jump to it; drag one if the app got it wrong and everything recomputes • The club's own path through the swing, tracked while the clip is analysed and drawn the moment you ask • Plane lines for down-the-line swings: two lines from the ball, through your trail hip and trail shoulder, fixed at address and held there. The wedge between them is the slot • Frame-by-frame stepping, 1x / 0.5x / 0.25x / 0.125x playback, and an A/B loop • Pinch to zoom; every overlay stays pixel-locked to you at any scale MEASURE, HONESTLY Tempo ratio. Spine angle at address and at impact, and how much of it you kept. Head drop. Hip sway and slide. Lead knee flex. Early extension. Shaft angle at address, and how far the shaft moved off it coming down. Lengths are in centimetres when the app can measure the scale of the picture, and in percent of your own height when it can't — inches from an uncalibrated camera would be invented. Every number names the frames it came from, and when tracking isn't good enough it says so instead of printing something. What one camera genuinely cannot see, the app refuses to guess at. COMPARE Two swings side by side, synced at impact — or one laid over the other as a ghost you can scale and drag into place. DRAW Angle tools, reference lines and freehand markup. EXPORT Burn the overlays in and share the clip — slow motion, annotations, skeleton, swing path, plane lines, phase markers. STROBE PRO One purchase, no subscription. It adds the coach with no account to set up, comparing two swings, and export with the overlays burned in. Everything else — capture, tracking, the checkpoints, every measurement and the drawing tools — is free and stays free. A COACH THAT POINTS AT THE FRAME (OPTIONAL) Off until you ask for it. It sends your swing measurements and a handful of key frames for a written read. What comes back is not a wall of prose. Every finding is anchored to one checkpoint: tap it and the player goes to that frame and marks it — the head, the line of the spine, the shaft — with the rest of the body dimmed. Walk the review a stop at a time, or ask a follow-up about any finding. Two ways to have a coach. Strobe Pro is one purchase, no subscription, with a monthly allowance of reviews and nothing to set up. Or connect your own Anthropic, OpenAI or Google account with your own API key: it is kept in your device's Keychain, the provider bills you directly, and we take no cut. YOUR VIDEO STAYS ON YOUR PHONE Recording, tracking, checkpoints, metrics, drawing and export all run on-device. A coaching review sends only measurements and a few still frames — to Strobe's coach server, or straight to your own provider account — unless you switch on Send the clip to the coach. NOT INSTRUCTION This is an analysis tool, not a substitute for a qualified golf instructor, and not medical advice. Metrics are estimates from a single camera and can be wrong. Work within your own physical limits, and see a professional for coaching or a clinician for pain or injury. WHAT YOU NEED iPhone running iOS 26 or later. 240fps capture depends on your iPhone model — the app falls back to 120fps or 60fps and says which it's using.
